Dennis Rader: The BTK Killer
At the end of 1970 until 1997, Dennis Rader, otherwise known as the BTK killer terrorized the Wichita Kansas area. Rader was convicted of killing 10 people over a 27 year period. The Otero family was the first victim of Rader’s reign of terror (Chu, Sieger, & Thigpen, 2005). In 1974, Rader strangled Joseph, Joseph Jr, Josephine, and Julie Otero. Left at the crime scene was Semen from the suspect masturbating over the lifeless body of 11 year old Josephine Otero (Chu et al., 2005). At the time, DNA technology was not yet available therefore the sample remained untested. (Chu et al., 2005). By 1979, the murder toll rose to three more victims (Chu et al., 2005). Approximately, 3 months after the Otero family murders Kathryn bright …show more content…
The disk BTK used to communicate with police was analyzed and the results eventually lead back to Rader. Rader believed that the police would not trace the evidence, however that was not the case. The Detective in charge of computer analysis quickly learned that the computer belonged to a Lutheran church. Once police arrived at the Church they realized that Dennis Rader was the last person to use the computer. Although Digital Forensics was strategic in the BTK case, many other police agencies were not knowledgeable in computer forensics. Digital evidence normally seized at crime scenes includes computers, cellphones, cameras, flash drives, etc. (Garrett, 2009). "Technology is becoming an increasingly important part of criminal activity, and agencies need resources and training to deal with it (Garrett, 2009)" Approximately, $200,000 would have to be allocated in order to effectively train officers on digital evidence (Garrett, 2009). Departments tend to “invest around $3,000 in training and equipment and expect $20,000 worth of performance” (Garrett, 2009). Furthermore, the digital evidence was a profitable resource that aided police in identifying a …show more content…
However, investigators could have put more effort into tracking the killer through his earlier letters. Rader sent 19 messages to police before he was finally arrested. The investigators could have released a profile of the killer based on the contents of the letters. Likewise, a geographic profile would have been beneficial in the BTK case. Geographic profiling is an investigative techniques that predicts an offender’s location based on where the crime is committed (Emeno, Bennell, Snook & Taylor, 2016). Geographic profiles have been proven useful in a wide range of crimes.A number of the murders, occurred in close proximity of each other. However, Rader lived miles from each location (Lynes & Wilson, 2015). Due to the close proximity one can conclude that he frequent this area. With a geographic profile police put pressure on the surrounding neighborhood causing a change in location. When an offender commits a crime in unfamiliar territory they are more likely to make a

Though the scientific technology that analyses the DNA produced from a crime scene is sound, “if you look at the various miscarriages around the world that have involved DNA, it’s almost always around the chain of custody areas of the DNA process”. The report by ABC Law Report, “Evidence in Criminal Trials” (2010), reveals that there…

    Tyranny. Something that has torn apart nations and civilizations for centuries. No wonder our founding fathers worked so hard to inhibit it. James Madison, the father of the constitution, wrote that power in the hands of one, few, or many is the definition of tyranny. The existing constitution, The Articles of Confederation, was not working for the young America. There was no chief executive, judicial system, or a central government to unite the states. After just separating from a tyrant king, the framers of our constitution wanted to create a strong defense against tyranny. The systems protecting our government against tyranny is federalism, separation of powers, and balance of powers.…

    Geographical profiling is defined as a method for evaluating locations connected to a crime in order to identify the probable area of an offender’s home location, place of work, or other relevant locations based off of nomothetic data and assumptions (Turvey, 2012). Dr. Darcy Kim Rossmo, a Canadian criminologist, is accredited for his influence on geographical profiling. Rossmo concluded in his research that offender’s geographical correlation to a crime is routinely based on offender residence, workplace and leisure activity (2012). Based on this theory, the Vancouver Police Department launched it’s first Geographic-Profiling Section in 1995. Since its establishment several agencies world wide, including the Federal Bureau of Investigations (FBI), have enlisted assistance from the Geographic-Profiling Section at the Vancouver Police Department to aid in their investigations.…

    After the preservation phase, forensics are required to locate and identify any evidence that can be used to aid the crime case. There are several locations where evidence are usually found such as in the hard drive on the user’s personal computer, laptop, smart phone or tablet (ACPO, 2012). It is also critical that forensics are aware of the intention of the particular investigation. This aids in the forensics' efforts of locating digital evidences that are relevant to the case. For example, in the case of a server intrusion, forensics should look out for signs such as a rootkit installation, analyze configuration files, logs files and etc. These are possible locations and processes where traces of evidence can be picked out from (Carrier and Spafford, 2003).…
