Psychopath Dennis Rader Case Study

This paper examines Carrell et al’s research along with three other scholarly research articles to better understand the effects that the DNA recovered from a crime scene has on a particular case and the forensic science community.

Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect’s guilt or innocence (Butler, 2005). The method of constructing a distinctive “fingerprint” from an individual’s DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA

DNA analysts have been profiling DNA since 1985. Then in 1998, the Combined DNA Index System became fully operational (“FAQs” 2010). CODIS’s three levels are the national level, the state level, and the local level. As September 2015, there is 14,740,249 DNA profiles in CODIS (“CODIS”, n.d.). Since everybody has different DNA, except identical twins, DNA analysts have been able to assists with investigator to determine between who is guilty and who is innocent. With some of their findings, they are able to exonerate individuals, who have been wrongfully convicted. Even though television may make DNA analysts’ life look simple on the screen, it is not. There is need for interest and education. Lastly, the actual job that entails for the DNA

DNA testing is a critical and accurate tool in linking accused and even convicted criminals for crimes, and should be widely used to assess guilt or innocence before jail sentences are imposed. It was started up by scientists Francis C. Crick and James D, Watson in 1953 as they had described the uses, structures and purpose of the DNA “deoxyribonucleic acid” genetic fingerprint that contains organism information about an individual (testing

The serial killer I chose to do my report on was Dennis Rader. Rader was born on March 9, 1945 in Pittsburg, Kansas and as of today he is still alive. Rader was the oldest of four sons. When Dennis was a child he hung stray cats. He grew up in Wichita, Kansas. Rader served our country by joining the U.S Air Force which he served from the mid to late 1960’s. He got married to Paula in 1971 and he work for a company that sold camping gear but he only worked there for a few years. He worked for ADT services in 1974.

Due to the uniqueness of DNA it has become a powerful tool in criminal investigations

DNA analysis of BTK 's semen and material taken from underneath the fingernails of victim Vicki Wegerle match the DNA profile

Technology in the late 60’s was insufficient to collect DNA samples from suspects, however, in 1998 Riverside Police collected skin samples from their only remaining suspect in the case. The results of these tests have not been released to the public.

Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011). By analyzing this junk code, Jeffreys found certain sequences of 10 to 100 base pairs repeated multiple times. These tandem

Fifty two year old police Lt. Charles Joe Gliniewicz was found dead in fox lake the officer was shot two times once in the back of his neck and another in the stomach which he had a bulletproof vest over. Investigators who have been only been working on this case for a week have already found video of three suspects two white and one black. The police are still looking for them as the suspects in question where who Lt Joe Gliniewicz was pursuing before being shot and killed. Authorities involved have investigated over 185 leads and had 50 of those individuals tested for the DNA that was found at the crime seen. And are working hard to find out who’s DNA was found at the seen. The case of gliniewicz ‘s death continues there is an internal

Dennis Rader, or the BTK Killer, was responsible for the murder of ten people between 1974 and 1991. He was known for writing letters to police after a murder that offered information that nobody knew. Eventually the murders and letters stopped, then in 2004 Rader sent another letter to police claiming responsibility for a murder that was not connected to him before. Thanks to advancements in DNA technology police were able to collect evidence from underneath the victim’s fingernails. Rader soon then sent a computer disk to a TV station and police were able to analyze the data from a document found on it and learned that the authors name was Dennis. There was also a link to a Lutheran Church that Rader was a part of. After police did a search including Dennis and Lutheran Church, they found that the church has a deacon named Dennis Rader. After police get a DNA sample from Raders daughter, they

The DNA Identification Act of 1993 was formerly known as the Omnibus Crime control and Safe Streets Act of 1968. Under the new act forensic laboratories are authorized to analyze DNA for identification purposes that are retrieved from crime scenes. With the regulations of the act the Federal Bureau of Investigation is obligated to follow standards such as setting standards for testing and issuing an advisory board to supervise the standards for quality assurance. Of the results under the act records are established of persons convicted of crimes, samples recovered from crime scenes, and samples from unidentified human remains.

Psychopathy is a personality disorder characterized by enduring diminished empathy, remorse, and disinhibited or bold behavioring antisocial behavior, A psychopath is a person with a psychopathic personality,which manifests as a moral and antisocial behavior. They lack the ability to love or establish meaningful relationships. Psychopaths fail to learn from experience. Psychopathy is among one of the most difficult disorders to recognize. A psychopath can appear normal or even charming. Underneath, they lack conscience and empathy. This makes them manipulative, volatile and sometimes (but by no means always) criminal. There are many symptoms associated with psychopaths.

DNA profiling technologies have had a considerable impact on how forensic science and criminal investigation have been understood, carried out, and regulated in the last 25 years. Current methods of forensic DNA profiling (known also as DNA fingerprinting and DNA typing), based on Polymerase Chain Reaction (PCR) amplifications of a varying number of Short Tandem Repeat (STR) loci found at different locations on the human genome, are regularly described as constituting the “gold standard for identification” in contemporary society. Prior to the implementation of PCR based extraction and amplification methods in the 1990’s, the initial uses of DNA fingerprinting (based on Multiple and Single Locus Probes) were largely confined to reactive

Every State in the Nation has a DNA database that allows for the collection of DNA profiles from offenders convicted of particular crimes. CODIS software enables State, local, and national law enforcement crime laboratories to compare DNA profiles electronically, thereby linking serial crimes to each other and identifying suspects by matching DNA profiles from crime scenes with profiles from convicted offenders. The success of CODIS is demonstrated by the thousands of matches that have linked serial cases to each other and cases that have been solved by matching crime scene evidence to known convicted offenders.
