Given a factual murder case students are to read information about the crime scene and evidence and apply logic and reasoning skills to determine the best procedures to use to solve the murder case.
As you work through the case you will be asked a series of questions that will help you progress through 10 experience levels to the head of the CSI Dept.
If you select the most appropriate answer you will move up a level.
Answers that are not the best decision will take you down an experience level.
You are a newly hired crime scene investigator and your first job is to investigate a thirteen year-old paperboy who was murder while delivering his papers. You will collect and analyze evidence from a crime scene. You must use logical thought processes and scientific inquiry skills as you trace the steps of the crime and determine whether or not the science accurately explains the crime.
6 The Paperboy
It was early on a fall morning in Bellevue Nebraska a few miles south of Omaha on Sunday September 18 1983. Thirteen-year-old Danny Joe Eberle had arisen early around six and was delivering the Omaha World Herald newspaper to seventy of his neighbors. Hed left his home on Valley Drive on his bike with the intent of getting done and getting back as quickly as possible. So when he failed to come home from his job his parents began to worry. It wasnt like him to not let them know if he was going somewhere. And there was an added concern The route supervisor had roused Mr. Eberle from sleep to let him know that Danny Joe had not finished the job. People were complaining.
7 The Paperboy Contd
The Eberles called around to people who knew him but no one had seen him. That made them apprehensive so they went outside to see if he was around and just hadnt told them. But Danny Joe was nowhere to be found and his brother who also had a paper route had not seen him although he recalled having been followed recently by a white man in a tan car. He had no idea if that was connected.
The events of that morning would rock the small town of just over 30000 residents. They would soon learn that there was a killer in their midst who could strike during the day without anyone noticing.
Danny Joe Eberle 8 The Search
Danny Joe had gone out without his shoes which was his preferred way to travel and had picked up his papers at a convenience store and rolled them there in a parking lot to place into his delivery bag. He had then set off to start his route but made just three stops that morning. When Danny Joes absence was investigated his bicycle was located at his fourth stop inside the gate of the cyclone fence around a dentists home. Folded newspapers undelivered were there as well in his bag. But not Danny Joe. It appeared that hed arrived been distracted and then abducted. But there was no sign of a struggle.
9 The Search Contd
The Eberles notified police and instigated a manhunt around the immediate area going to each person on Danny Joes route and to other areas that may have attracted him but nothing turned up that day. They continued with the search going from building to building house to house but no one had seen Danny Joe with anyone. He had simply vanished. In all Pettit says some 130 officials made up the search team. Despite this impressive response no clues were found and day became evening so when darkness fell the search was called off.
10 In such a situation when the initial search produces no results the police should Regroup and consider a strategic search. End the immediate search and wait to see if the boy showed up. Keep searching no matter how long it took. 1 2 4 Request federal assistance. 3 Click on one of the figures to select your answer. 11 Correct you have gained an experience level!
The best answer is 2). Searching at night may cause the searchers to miss something or risk contaminating a crime scene. Once the all-out search of the immediate area fails its better to come up with a plan. The police may call the FBI but not until its clear that theres been a kidnapping or murder. In addition since Danny Joe had not shown up the entire day its unlikely that hed just come wandering home the next day so a search should continue but with a clear plan.
The next day the police went over a large area in town and fanned out into the fields around town. Monday went by and then Tuesday with no progress. No one came forward to say theyd seen something and nothing else belonging to Danny Joe had been found. They could only hope he hadnt been killed and tossed into the river for then they might never find him. On Wednesday they finally had a break. One of the searchers called out that hed found the package a code word to investigators.
Arial view of where body was found. 13 Found Contd
Danny Joes body was located off a gravel road about four miles from where hed left his bike. He was clad only in his underwear. Hed been stripped killed and dumped into some weeds that were tall enough to have barely hidden him. He had been stabbed nine times front and back and his ankles were bound with rope. There was reason to believe that before hed died he had been tortured. He had likely been alert for several minutes before he bled to death and knew that he was being killed.
Because there were impressions from pebbles on the body but not many where it had been dumped it seemed that Danny Joe had been moved from one spot to another. Police officers got busy with the crime scene.
14 What is the first thing investigators should do 2 Look for potential witnesses. Search for Danny Joes missing clothing. 1 Remove the bindings. 4 Take photographs of everything. 3 Click on one of the figures to select your answer. 15 Correct you have gained an experience level!
The best answer is 3). The first order of business once its clear that a victim is dead is to photograph everything for documentation. If the team is large enough others may be sent to seek witnesses or look for evidence but the crime scene must be preserved on film before any alterations occur.
16 Profiler Clothes of victim discovered.
The investigators documented the scene looked for evidence in the surrounding area and searched for Dannys clothing. That this child had come to such a terrible end depressed them and they were determined to find the perpetrator.
Because the murder involved a child and because President Reagan had recently put murders and the kidnapping of children under federal jurisdiction the local police called the FBI office in nearby Omaha. They responded by sending Special Agent John Evans to the scene. He also referred the case to the FBIs newly formed Behavioral Sciences Unit. The unit had known some success with assisting local jurisdictions with multiple murders including providing some ideas that helped to close the case on the Atlanta child murders in 1980. But they were largely an unknown to police departments and behavioral science was itself suspicious to hardened cops.
17 Profiler Contd
Special Agent Robert Ressler traveled to Nebraska to talk with the authorities there. Hed been on his way to a homicide seminar when he got the call and went immediately to Omaha. From the few details he heard about a missing newsboy he was reminded of another case a missing newsboy in Des Moines from the year before who had never been found. He wondered if there was a connection.
18 Profiler Contd
Its always important to understand the town demographics when such incidents occur. Bellevue was a Midwestern small town largely reliant on employment from the nearby Offutt Air Force Base where the Strategic Air Command was situated. Danny Joes father had once been in the Air Force. It was a tight-knit community where people normally felt safe.
What Ressler particularly liked about being involved in the investigation from the start was getting to see things firsthand. That way he could decide which items were important and which items might just complicate the process. When he arrived in Omaha he went to see the site where Danny Joes body had been found. He was looking for specific clues.
19 What about the crime scene might give Ressler clues about the perpetrator The out-of-the-way location. 2 The long grass. The proximity to a major city. 1 4 A crossroads that led to a river. 3 Click on one of the figures to select your answer. 20 That is not the best answer. You have lost an experience level.
The best answer is 3). The first two are too general to be of much use but the fact that the perpetrator did not take advantage of using the river as a means of disposal indicated that he was not strong enough to carry the body and/or he did not realize there was a river that close to the crime scene. Because Ressler believed that the perpetrator was familiar with the area he must have therefore been slight of build.
21 Initial Impressions
There were a number of signals that the killer was not overly concerned with concealment which indicated compulsive behavior or something he could not easily control. Ressler thought it was significant that the perpetrator had left Danny Joes body in a place where he might have been seen. It was a dead-end road but not far from an area where people would have been driving. In addition the offender had picked Danny Joe up during the early daylight hours and he hadnt bothered to take his prey further down the road to dump him in the river. To the offender the body could be found fairly quickly and his behavior indicated that he did not care. Even if it had still been dark when he left the body there someone passing by could easily have spotted him or his vehicle in that spot. It was high-risk behavior.
22 Initial Impressions Contd Rope used to tie victims hands.
The news reports the next day indicated that Danny Joe had been stabbed but Ressler said it was worse than that. He lay face-down in the weeds his hands and feet bound behind his back with a rope. His mouth had been closed with surgical tape which was also used around his ankles and wrists. His clothing except for his undershorts had been removed and hed been stabbed multiple times. Hed also been hit in the face and his neck was slashed. Under the tape over his mouth according to the medical examiners report a pebble had been found. That indicated that the boy had been a captive for a short time somewhere other than where he was found rather than killed quickly at this site. In that case it seemed most likely that hed been murdered shortly before he was found. While it appeared to have been a sexual crime there was no evidence of outright sexual assault before or after death.
23 Initial Impressions Contd
Other boys including Danny Joes brother reported that a man in a tan car had followed them in the days before the abduction. Hed never approached them but in light of these circumstances it now appeared to be suspicious. He might have been scoping out the area and making his selection.
Investigators got busy trying to find the source of the pebble found in Dannys mouth. If they could identify an area that contained such pebbles they might be able to find more evidence and possibly the missing clothing. They did locate a potential source but around the same time the ME admitted that hed made a mistake in his report. He had mixed up Danny Joes case with another one and no pebble had been found in Danny Joes mouth. That was both disappointing and frustrating for investigators. They had thought they were closing in on a potential lead.
24 Such a mistake has serious consequences for investigators. Why It wastes investigators limited time and resources which could be applied to something more productive for the investigation. 2 1 It routes resources toward a specific type of investigation. 4 It undermines the autopsy report. It erodes confidence in the investigative process. 3 Click on one of the figures to select your answer. 25 That is not the best answer. You have lost an experience level.
The best answer is 2). The most serious consequence is that the pebble appeared to be a clue and the police spent a week looking for similar pebbles when they could have been doing something more productive for the investigation. It doesnt undermine the autopsy report since the documentation of wounds did not yet provide leads and would not undermine confidence in most of the task force members. Mistakes are made which does not indicate that the person making them is inept or corrupt. If the ME had a good record its just a mistake but in this case it cost precious time. Decisions about the type of investigation to use does not rest with the MEs findings but with task force leaders and they would likely not just select one lead and follow only that.
26 FBI Report
Given all the information what little there was Ressler put together a preliminary report of his impressions. The Behavioral Sciences Unit had an approach that had not often been tested but Ressler felt confident that from his long experience with the Armys Counter Intelligence Department and his investigative years with the FBI he could give a fairly accurate idea of the type of offender the task force composed of the local and county police and the FBI might be looking for.
27 FBI Report Contd
Given the witness reports from the boys Ressler knew that he ought to be on the lookout for a white man in a tan car. He added based on his knowledge of sexual predators that the man was probably young in his late teens to early twenties. Danny Joe had been abducted from a white neighborhood and no one had reported a suspicious stranger which seemed unlikely if a black Asian or Hispanic male had been hanging around. Ressler believed that the lack of a report confirmed his instincts that this had been a white man. It seemed possible since there was no sign of resistance or a struggle that the man was either friendly and non-threatening or that Danny Joe had known him and felt safe.
28 FBI Report Contd
There was also reason to believe that the perpetrator was not experienced with killing. In fact Ressler ventured to say this was his first time I thought it had to be his first murder. It might also be the case that there had been more than one male operating together one to lure the boy one to hold him down during an assault. The method of dumping suggested panic rather than experience but the perpetrator was more than likely familiar with the area because he knew abut the dead-end road. Ressler did not believe that Danny Joe had been bound while held captive.
29 Why might Ressler believe the perpetrator was familiar with the area His behavior while apparently high-risk could also indicate that he believed the area was isolated and lightly traveled. The crime bore the signs of a quick hit opportunity such as a transient passing through town might commit. 2 He knew how to get out of town. 1 3 4 He realized that the state line was only a few miles away. Click on one of the figures to select your answer. 30 Correct you have gained an experience level!
The best response is 2). The area was a dead-end road which meant the perpetrator believed he could bring a victim there and kill him without much chance of getting caught. No one knows if he got out of town or went right back in and the crime bore the signs of someone who had spent some time with the body so he was not in a hurry. The crime also looked somewhat planned rather than a crime of opportunity. The state line seemed irrelevant to the behavioral analysis because it would have been better to have committed the crime over the state line to confuse the jurisdiction.
31 FBI Report Pt. II Final Score
Besides being local the perpetrator was thought to be in possession of no more than a high school education. He was likely employed in a job that required few skills. While the crime had likely been preplanned it seemed to lack follow-through as if only one part of the fantasy had been worked out which showed a lack of intelligence and experience. Because it seemed to have been a sexual crime without penetration it seemed likely that the perpetrator was driven by fantasies but not by experience except for some forced molestation of younger children when he was a child. He was probably single and likely had a mental imbalance or emotional problem that had long been part of his life. He was deviant to be sure but it was not altogether clear in what manner.
32 FBI Report Pt. II Contd
In terms of what to look for Ressler thought that given the possibility that Danny Joe was held captive somewhere for a couple of days the perpetrator might have missed some time at his job if he was employed. This last characteristic I suggested because of my interviews with murderers Ressler wrote. Many such as David Berkowtiz had told me that the right time around the murder was quite important to them so that they had absented themselves from their usual routine before and after it. In addition the perpetrator might try to inject himself into the investigation ostensibly to assist but actually seeking information. In that case if a drawing was made it should be kept within the law enforcement community.
33 FBI Report Pt. II Contd
The fact that hed been out that early in the morning suggested that he might have been up all night drinking and that he had no one to report to. Substance abuse might have empowered him to actually commit the crime. Ressler thought that hed considered dismembering the body but had decided instead to dump it. His killing seemed tentative and spontaneous rather than clearly planned. The killer had also made some unusual wounds on Danny Joes leg and shoulder possibly to conceal a bite mark.
Ressler delivered his ideas in a round-table format to the core group of investigators. He indicated that the perp was probably a loner with latent homosexual tendencies who worked in some capacity that brought him close to children such as a coach or Boy Scout leader. He did not believe the man was a serial killer.
34 FBI Report Pt. II Contd
The task force put surveillance on the dump site Danny Joes grave and the general neighborhood from which the boy had disappeared in the hope that the killer might show up to relive the experience. Shortly after the funeral service says Pettit a man called the Eberle home to ask if Danny Joe could come outside and play. (There is no mention of that call in any source.) Danny Joes mother did not recognize the voice and there was no way to trace the call. Nothing else occurred and no one was arrested. Danny Joes grieving family was left to wonder if someone would be made to pay for what had been done.
The bindings and the rope used on Danny Joe were sent to the FBI lab for analysis as were some strands of hair that appeared to be from a source other than Danny Joe. The rope proved to be unique and difficult to identify.
35 In what way might this difficulty assist the investigation It would prove to the community that they were doing everything possible to follow leads. It would keep them focused on the right evidence. 2 It would more easily be linked to rope in the possession of the perpetrator than would more ordinary rope. It would broaden their knowledge about ropes. 1 4 3 Click on one of the figures to select your answer. 36 Correct you have gained an experience level!
The best response is 3). The point of following a lead is not to prove anything but to find evidence that will assist in the prosecution of the crime. If they can show how unique the rope is and also link it to the perpetrator they have a good circumstantial case.
37 A Suspect
A week after the murder a young man was picked up for molesting two young boys. Pettit uses the pseudonym Alvin. The case against Alvin looked pretty good He failed a polygraph lied about his alibi a sample of his hair was consistent with the hair found on Danny Joe and he had suspicious items in his home such as a rope tape and a knife. To the task force he seemed to match the kind of person they were looking for but Ressler who had watched him being questioned believed he was not the guy.
38 A Suspect Contd
The task force was in a tough position because they just werent certain. They did not want to get the wrong person but they also wanted justice for Danny Joe and his family as well as closure for the community and a restoration of the feeling of safety. In the end thanks to sparse evidence they decided against charging Alvin for the crime.
They then questioned known pedophiles in the area including an Air Force major who liked cruising for boys and a gay man who persuaded boys to undress for photographs. They checked out one person after another but found nothing to incriminate any of them in the case. The lack of evidence was frustrating and eventually the murder of Danny Joe Eberle became a lower priority. It seemed that whoever had done this had managed to slip away. He might not even be from the area. They could only hope that whoever he was he would not strike again. But that was too much to hope for.
39 Second Strike
Newton describes the second incident. On December 2 two and a half months after Danny Joe Eberle was murdered Christopher Walden was walking to school when he disappeared. At least two witnesses had seen him get into a tan sedan with a white male. Walden 12 had lived in Papillon Nebraska which was in a different town but only three miles from where Danny Joe had been found. He was the son of a military officer at Offutt. While the FBI had decided there was no connection between the newsboy missing from Des Moines (who still had not been found) and Danny Joe this new incident appeared to have more similarities. Almost at once when Chris could not be found they believed that the same killer had struck twice.
40 Second Strike Contd
The witnesses both women were put under hypnosis to try to get more details about what they might have seen. They offered descriptions of the man with Walden saying he was of similar build short thin and young. One person remembered that hed also been wearing a woolen cap pulled down over his forehead although the other recalled no cap. One had seen the license plate and with her memory more focused in a trance she offered the first seven digits. But that gave the detectives the task of checking out over a thousand vehicles in Nebraska with those numbers. It could be a time-consuming task with no guarantee that she had even recalled the numbers correctly. Hypnosis is not perfect and it later turned out that both women had gotten several key details wrong.
41 When using hypnosis investigators must keep all of the following in mind except Be cautious about suggestive questioning. Be aware of court cases involving hypnotically refreshed testimony. 2 1 Use and experienced professional. Dont tell the witness what information was provided in a trance state. 4 3 Click on one of the figures to select your answer. 42 Correct you have gained an experience level!
The answer is 3). There are court-sanctioned guidelines for the use of hypnosis with eyewitnesses including documentation and the use of a professional. The reason is that people who are inexperienced with hypnosis and eager to solve a case might suggest things that the witness will then accommodate subconsciously. Anyone who uses hypnosis must be aware of the state guidelines for legal proceedings and nothing demands that the witness not learn what he or she said in a trance state.
43 Grim Discovery
Two days later two pheasant hunters came across Christopher in the woods in a dense area five miles from town. They recognized his photo from the papers and called the police. He was clad only in his underwear and had been repeatedly stabbed. In addition after death his throat had been cut so deeply that it had nearly removed his head. There was also a strange mark on him a figure of some kind carved into his torso. Some called it a star pattern and in court documents later it was referred to as resembling a plant. Clearly the boy had been aware of what was happening to him as he bled to death from seven stab wounds. If this had been done by the same killer and there was good reason to believe it had then he was escalating in his violence. Two sets of footprints going to the site and one leaving indicated a sole offender. After an examination it was found that there had been no sexual penetration.
44 Grim Discovery Contd
Ressler received the call once again. John Evans told him that another boy had been abducted and murdered in the Omaha area. When the crimes were compared it was found that the two boys had been similar in height and build so they might have attracted the offender by appearance. Ressler revised his profile to indicate that the killer was probably in his twenties and said again he was likely not very large. Both boys had also been abducted and taken away in a vehicle. Both were forced to strip and neither were sexually assaulted. Ressler viewed this as a killers anger with himself and a denial of his homosexuality. In his book he says that he went out on a limb to say that it could be an enlisted man who does mechanical work and is not intellectual. He reiterated that this person would likely be involved in some occupation dealing with children.
45 Grim Discovery Contd
Yet there were differences too. Ressler thought that Danny Joe had been held captive and then killed while it appeared that Christopher had been taken and killed immediately right there were his body was left. Danny Joe had been left in a fairly visible place near a road while Christophers body had been better concealed. Danny Joes clothing had been taken while Christophers was piled near the body. Danny Joe had been bound with rope and tape but Christopher had not.
46 The differences between the two crime scenes might most likely indicate One was a statement to society the other was for the killers private satisfaction. The likelihood that the killer was getting better at it. 2 An indication that the first crime had been planned but the second one had not. 1 Proof that there was more than one killer. 4 3 Click on one of the figures to select your answer. 47 Correct you have gained an experience level!
The best response is 2). The fact that the second boy was not bound indicated that the killer felt more confident of his ability to restrain the boy and overpower him without binding him. As to proof there was no proof of anything yet and it was not possible to interpret the killers actual motive or the killers level of planning in each crime.
Ressler and Evans decided to tell the media to warn parents and children about someone lurking around schools and churches any place where child-ren might congregate. A warning might make people extra cautious because both FBI agents believed that the killer might strike again during the holidays when more children were out playing. The task force practiced a quick response to any indication that the man was in the area.
The FBI technicians were busy trying to learn the origin of the rope that had been found on Danny Joe. It had been braided with several colors and was not available in any of the local stores. That made the rope more interesting and more frustrating. Unique ropes such as this one were helpful because their distribution was limited. Yet this rope was so unusual that no one could figure out where it originated.
Specific strands in rope. 49 Rope Contd
Rope is made by twisting yarns in specific ways to strengthen them and the type of yarn used can help to identify a manufacturer although the more common the yarn the less likely that one can be certain that one piece of rope had the same origin as another that looks like it. This rope had several colored yarns and an unusual construction.
The FBI set about checking with every rope manufacturer in the country as well as abroad seeking help from Scotland Yard. They even went to dealers in the Far East but each attempt was frustrated. No one seemed to have ropes that matched their sample. Fortunately another incident gave the investigation an entirely new direction.
50 Fortuitous Incident
On January 11 1984 a staff member of a preschool spotted a young man driving around in the area seemingly scoping it out. The town was on the alert for such people especially after the reports of a white man in a car following young boys so the woman took note of his license plate number. (Ressler says he was loitering but Evans indicates he was driving by and when he saw her write down his number he stopped and demanded that she give him the paper. Pettit says he was driving by and got out of the car to ask her for directions and she memorized the number to write down later.) She later reported that he said he would kill her and when she eluded him he ran to his car. As he fled the scene the woman ran for help and called the authorities.
51 Fortuitous Incident Contd
The car was not tan as they had hoped and did not have a matching license plate number but they went to work on this tip anyway. At least she knew that the car shed seen was a Citation. They traced the vehicle says Evans to a dealership that had rented the car to John Joubert a twenty-year-old enlisted man at the Offutt Air Force Base while his own car was under repair. That was interesting. He had another car and it turned out to be a tan-colored Nova sedan. The license plate contained two of the seven digits (some sources erroneously say all seven) reported by the witness under hypnosis. It appeared they had a real break in the case and they rapidly prepared themselves.
52 Fortuitous Incident Contd
As they learned more about John Jouberts background a warrant was issued to arrest him and search his quarters. That search turned up an important item rope that seemed consistent with the rope used to bind Danny Joe. A search of Jouberts car turned up more rope and a large hunting knife (Ressler says this was in his quarters). There was also a stack of racy detective magazines and Ressler indicates that one contained a story about the murder of a newsboy. While DNA analysis had not yet been discovered and applied in criminal cases (that was two years away) the rope proved to be essential in making the case. Because of its unusual composition it was nearly as good as other types of identifying evidence such as a fingerprint.
53 Fortuitous Incident Contd
Joubert was arrested and charged in the murder of Danny Joe Eberle. That same day the FBI indicated that the rope from the Danny Joe Eberle murder had likely been made for the military in the Far East. That fact would soon become crucial.
A comparison of Resslers profile against Jouberts situation showed that Ressler had gotten a number of things right. Joubert was 20 resided at least temporarily in the area was sexually disturbed was an enlisted man who worked with radar was of a slight frame (five-foot-six and slender) and was good with his hands. He was also according to Evans and Pettit an assistant scoutmaster which gave him access to boys. He hadnt been at it long but long enough to have become good friends with the scoutmaster and one of the boys in his charge.
54 Fortuitous Incident Contd
In fact before his interrogation says Pettit John Joubert asked to speak to the boy and reassure him that hed never been in any danger. That cleared the way for a confession which was precipitated by two things.
55 What evidence might the interrogators use effectively to disturb Joubert sufficiently to start talking The knife found in his possession. 2 The way the body was stabbed. 1 The rope. The crime scene photos. 4 3 Click on one of the figures to select your answer. 56 That is not the best answer. You have lost an experience level.
The best response is 2). They had found detective magazines in his possession so he probably knew that wound analysis and an ordinary knife might not be sufficient to pin murder on him in court but the uniqueness of the rope could be disconcerting. Using crime scene photos to attempt to make him feel guilty actually risked making him feel powerful.
The investigators showed Joubert the rope theyd removed from his room and car noting that it was extremely rare. He resisted this notion at first but admitted that hed gotten it from the scoutmaster who had brought it back from Korea. (As it happened the FBI had just discovered that the rope was from Korea.) He seemed taken aback that it could place him at a crime scene.
While he was vulnerable Lieutenant Jim Sanderson of the Sarpy County Sheriffs Department approached him with a way to make an admission without fully committing himself to a full confession. He talked with Joubert about his bad side the part of himself that compelled the good part to do something he knew to be wrong. It wasnt long before Joubert was ready to admit to everything.
58 Interrogation Contd
He said that hed killed the two boys and told the detectives interrogating him that he would likely kill again. He seemed relieved that theyd stopped him. The FBI confirmed that the rope in Jouberts possession and the rope used to bind Danny were microscopically identical. Given how rare the rope was it would make a solid case. They also compared a hair from Jouberts car to both victims and found it to be consistent with Danny Joes hair sample. On January 12 Joubert was charged with two counts of murder and held for trial. But the trial never happened. On July 3 after initially pleading not guilty he pleaded guilty to both counts.
59 Interrogation Contd
There were several psychiatric assessments of Joubert at this time and Pettit includes three of them. Ressler discusses another. He was variously labeled as obsessive-compulsive sadistic and suffering from schizoid personality disorder. This meant that he had strange beliefs but was not psychotic. They noted how he managed to distance himself from the atrocity of his crimes and didnt care much about anyone. He blamed his mother for many of his childhood problems and had developed a ritualized approach to the murders. Yet all of them concluded that he knew that what he was doing was wrong and that he had a certain degree of control over his behavior. That made a mental illness qualification of his sanity untenable He had not been psychotic at the time of the crimes.
60 Interrogation Contd
A panel of three judges decided that given the senselessness and brutality of the crimes and the fact that he had killed the boys to evade detection Joubert should be executed.
But the story wasnt over. Joubert had lived elsewhere and his case in Nebraska was making authorities in Portland Maine take another look at one of their own cases. Ressler says that he was showings about the case to a group of police officers during the fall of 1984 and one of them recognized the similarity to an unsolved crime in his jurisdiction. Ressler adds that while hed initially said that the Eberle murder was the offenders first hed revised his opinion after learning more about Joubert.
61 What does this shift indicate about criminal profiling Its not valuable to an investigation. Its accuracy relies on accurate input. Its not very accurate. Its not flexible. 1 2 4 3 Click on one of the figures to select your answer. 62 Correct you have gained an experience level!
The answer is 3). A profile is intended to help investigators narrow suspect leads and its not proposed as a scientifically accurate instrument. Its accuracy relies on accurate input and as an investigation progresses and more or better information is obtained the profile may (and usually does) shift on some items. Its meant to be flexible and the more information becomes available the better it will be as a tool. Jouberts amateur approach indicated inexperience with murder but his long history of violent fantasies learned only after he was arrested opened up the possibility that hed killed before.
