Compare of serial murders investigators Timothy F. Goodson Albright College Crime and Justice This is the critical and comparative analysis of the two books that were required readings for this Advanced Criminology Seminar. The two books tied " Whoever Fights Monsters " by Robert H. Ressler and "Journey Into Darkness" by John Douglas. In this comparative analysis I will look at the differences of the a of the authors Ressler and Douglas, their differences in profiling, and my personal reaction to both of their books. In likeness both Ressler and Douglas were career agents with the Federal Bureau of Investigation (FBI). The investigated violent crimes that came came under the jurisdiction of the FBI.
The lab was asked specifically to determine any fingerprints, presence of blood, indentify hair and fiber; and determine manufacturer and date of tongs as well as kind of metal and weight. It was noted blood and hair samples were available at the Cuyahoga County Sherriff’s office. In addition, based on the policeman’s report, who was first at the scene of the crime, there appeared to be no forced entry but blood was found on the victim’s pillow as well as all over the floor. He also reported that the doctor’s medical back was open on the floor with the contents spilled out. Later, the corner claimed that the victim was probably killed by a surgical
Once the vehicle was secured, the forensics investigators began doing an investigation to determine what type of evidence could be found in the vehicle which could lead to naming a certain individual that had contact with the vehicle. They began doing blood swabs on the gear shift, and fingerprints all over the vehicle. Nothing was found. They then sprayed the vehicle and then used an ultra violet light which made blood and a fingerprint become visible to where investigators could get the evidence for possessing. They found blood on the steering wheel, and a fingerprint on the passenger side door window.
Ted Bundy would rape strangle and beat young women and girls. Bundy would fake injury to get his victims inside his car and beat them to death sleeping with their dead corpses. There was no suspects because during his murders which occurred before dna profiling he had mastered the art of leaving minimal evidence behind. There was a number of pieces of evidence that led to Ted Bundys conviction. After police found Cheryl a victim of Bundy found badly beaten and raped they were able to obtain a blood type from the assailant, sperm samples and fingerprint smudges.
For example, in the case of a sexual assault where an evidence kit is collected from the victim, a DNA profile of the suspected perpetrator is developed from the swabs in the kit. The forensic unknown profile attributed to the suspected perpetrator is searched against their state database of convicted offender and arrestee profiles (contained within the Convicted Offender and Arrestee Indices, if that state is authorized to collect and database DNA samples from arrestees). If there is a candidate match in the Convicted Offender or Arrestee Index, the laboratory will go through procedures to confirm the match and, if confirmed, will obtain the identity of the suspected perpetrator. The DNA profile from the evidence is also searched against the
The technician collects physical evidence such as bullet casings, footprints, hairs, guns, fibers, fingerprints, DNA and clothing fibers. It is the forensic technician's duty to ensure the evidence is collected properly using strict chain-of-evidence procedures such as placing items in separate bags and sealing them tightly. A technician correctly documents all the physical evidence collected by location, nature and type of evidence. One of the duties that a forensic technician does at a crime scene is document the evidence. Documentation of the crime scene involves a variety of activities including photography, videography, and crime scene sketching.
Fingerprints show ridge ending, enclosures, bifurcations, and trifurcations. Shoe impressions, the investigator looks at the heel design and sole design and the manufacturer’s name. Tool impressions is another type of evidence. Tool impressions are nicks, dents, broken edges, and striations on tools. Investigators or criminalistics need to know a few things in order to make the determination that glass was broken from the inside or the outside.
Moore and Wideman had joint trials and they were identified by an eyewitness who was at her mailbox and saw two men in her neighbors’ backyard. She gave a statement to the police of generic descriptions of two black men. She did not see either man’s face. She was later taken to identify Moore and Wideman, who were the only two people present that were not in official uniforms suggesting to the witness that they were the guilty men. The identification was ruled too suggestive.
On Ron Goldman's (one of the victims) shirt and inside the knit cap, hairs were also found. The hairs were matched to O. J. Simpson's hair. On the glove found at O. J. Simpson's estate, hairs were found matching the hair of both victims. Usually, hair analysis involves microscopic observation which determines whether the hair samples were human and compares the known hair with the samples observed (Deedrick, 2000). In O. J. Simpson's case, due to the racial factor, investigators also compared the racial characteristics displayed in the known and unknown hair samples.
From the evidence revealed by witnesses to the CSI team, it revealed that there were more than one suspect who they were looking for. Upon collection of evidence and questioning of witnesses they narrowed the search to a couple who had been identifies in both locations. Additionally, one of the suspects had been identified by the bloody fingerprint she had left behind at one of the crime scene and saliva residue found in one of the victims ears. Both samples revealed the blood and saliva sample belonged to a
