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.
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 death was ruled a homicide, by medical examiner Dr. Jan Garavaglia and that she had likely been killed by undetermined means. The Body Farm is a key battle in the Caylee Anthony case. Investigators of the case sent carpet and odor samples from the trunk of Casey Anthony’s car to four scientist at the Body Farm in Knoxville. The four scientists claimed that there could have been a decomposed body in Casey’s car shortly after Caylee went missing. There were DNA test from Oakridge National Laboratory in Tennessee showing evidence consistent with decomposition.
Explain how investigators used reference samples to determine that the victims had been held at the residence located at 881 Lope De Vega. 3. Explain how investigators used reference samples to determine that the victim’s bodies had been buried and later moved to the site where they were discovered. Also explain how they used such evidence to determine the original burial place. Some of the main challenges the investigators were facing in the case involving U.S. drug agent Enrique Camarena in Guadalajara were the crime scene was not secured and was contaminated by police and people who just wanted to look.
Furthermore, blood is similar to common fluids however, blood is held together by powerful cohesive molecular forces that generate a surface tension within each drop and on an external surface (Nordby). Furthermore, investigators have recounted aspects of a crime by the use of bloodstain patterns. Like when it happened, in what area the attack took place, what kinds of weapon or weapons was used on the victim, and where or how close the attacker was to the victim. But how could we have accomplished attainable information from strings? According to forensic scientist’s, the strings themselves are not as substantial.
Early work on offender profiling by the FBI indicated a broad distinction between organised offenders and disorganised offenders. This distinction was based on interviews and case details of 36 serial sex offenders who volunteered to be interviewed about their crimes. Since its first appearance, the organised/disorganised distinction has been widely cited in academic literature and used as a model by professional investigators. According to the Crime Classification Manual (Douglas et al., 1992), the organised/disorganised typology can be applied to all sexually motivated murder and some cases of arson. In 1992, Douglas suggested that a third category of ‘mixed’ offender be added to the twofold category system, to accommodate those offenders who cannot easily be categorised as either organised or disorganised.
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
The facts of the case were as the following there was a killing of an unarmed black teen walking home from the store where he purchased a bag of skittles and a Arizona ice tea. There was no eye witness to the event other than Martin and Zimmerman. I think that if Zimmerman would have let the police handle this matter and stayed in his truck after call 911 and giving a description of martin, who was doing nothing wrong but walking home from the store no of this would have happened, I think there were inconsistencies in Zimmerman’s stories in which he told a couple of different ones. It was proven that Zimmerman had prior knowledge of the stand your ground law and self- defense laws as well .Zimmerman should have been asked to take a lair detector test to prove his innocence. With the evidence that I saw a young black male was killed and there was no punishment for that action even Michael Vick got two years for fighting dogs it make some of wonder about the justice system of the United States Of America The
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.
Forensic Pathology Paper Forensic pathologists are interesting to me because they are commonly used when the cause of death of an individual is considered to be suspicious. The role of a forensic pathologist is to establish the cause of death in an individual. They perform autopsies, study and analyze physical evidence that is used in criminal court cases. First, forensic pathologists are physicians, but they must also have knowledge of several other forensic disciplines or sub-disciplines. For instance, forensic pathologists must be able to apply areas of toxicology, firearms examination, trace evidence, forensic serology and DNA technology to their investigations to determine the cause of death of each individual case.
