Wichita District Attorney Nola Foulston devoted approximately twenty hunting the serial murderer known as BTK, for "Bind, Torture, Kill." When she commenced in the 1970s, no agency was utilizing DNA evidence. However, by 2005, when she sensed she was almost apprehending the killer, familial DNA links were a significant part of the detective's toolkit. Foulston possessed samples of the assassin's DNA extracted from the scene, and she had a robust thought that BTK was a male known as Dennis Rader. She required to know if Rader's DNA corresponded with the murderer's. However, the law enforcement officers could not request Rader for samples. Under the order of a judge, the medical facility provided the detectives with samples of his spawn's DNA. In regards to the documentary, Rader initiated a sequence of communication with the local media stations that connected the police to recognizing him as the long sought BTK. Rader disseminated a diskette to Fox TV that contained a metadata a file marked as ‘Christ Lutheran Church’ that had been altered by Dennis. Internet search connected the law enforcement agencies Dennis Rader. Rader had been tracked during an occurrence at home yard whereby he utilized black Jeep Cherokee found outside his house by the police. Whilst new technological advancements might not be full-proof, DNA analysis remains to be the main course of forensic investigation. The latest of the technological advancements is known as Snapshot, which integrates DNA information and interprets it into conceivable physical characteristics of a suspected in criminal, in this case, Rader. DNA sequencing consents the forensic researchers to sequence short tandem repeat markers, possibly leading to an improved capability to distinguish between persons in multifaceted DNA combinations (Farley, 2019). In addition, different marker forms such as the single nucleotide polymorphisms may be easily assimilated into casework research laboratory. This may result in new abilities, for instance, lineage or phenotype forecast in unresolved cases. I mage enhancement technologies are allowing detectives to assess the evidences such as thumbprints, paths and bite marks. Data retrieval from databanks, for instance, the Combined DNA Index System (CODIS) and the Automated Fingerprint Identification Systems (AFIS) assist in cracking cases that may have been impenetrable years back. In addition, it is allowing law enforcement agency to gather proof from e-mails and other digital records. This is seen when detectives trace the disk sent to the church by Rader and facilitated his apprehension. His capture was facilitated by the new use of technology by the law enforcement agencies. This is enhanced through the use a computer-generated programs that assisted in narrowing down the victims’ homes to a three-and-a-half-mile range. This was accompanied with other topographical reporting strategies (Hickey, 2016). The enforcement agencies realized that he was selecting his fatalities in his comfort zone. It was also the technological advancements which led to producing a link that facilitated the downfall of BTK. This is attributed to him sending a computer disk that allowed law enforcement agencies to trace him back to the house of worship. In addition, Rader sent numerous mails to the newspapers, news stations, and law enforcement agencies, whereby he laid bare the facts of his deeds and went to the extent that of his own wrongdoings to local administrators. When he did not obtain the form of attention he looked-for from the local newspapers, he inscribed additional mails questioning the number of victims he was required to kill prior to making it the newspaper’s front page. In his communication modes with the several forms of media and law enforcement agencies, he purposely spelt words erroneously and practiced inappropriate syntax so that he may be seen as ignorant, but Rader is extremely smart.
