Prior to his eventual arrest, the search for Rader went cold until police received a bizarre letter, asking if they could trace information off of a floppy disk. The police lied to Rader, telling him that there was no way of tracking him down from a disk. Once police convinced the BTK Killer to send them the disk it was only a matter of time before they were able to uncover that the author of the letter was named Dennis, who owned a black Jeep Cherokee and had a connection to the local Lutheran Church.

Despite the extensive circumstantial evidence, police needed more concrete proof. In a controversial move, the police obtained DNA from Rader’s daughter’s pap smear. The DNA matched evidence found under the fingernails of a BTK victim. With the combined DNA evidence and Rader’s twisted letters, police were able to make an arrest.

Once on trial, Rader gave a chilling account of his crimes and got 175 years in prison without the possibility of parole. Perhaps if Rader had not been so brazen with police, he would still be terrorizing Kansas…

Israel Keyes made killing a hobby, studying famous serial killers and striving to defy the trademark behaviors of past murderers. To elude police and differentiate himself from other serial killers, Keyes avoided murdering close to his home and never killed in the same area twice.

Despite his methodical nature and high intelligence, Keyes was eventually apprehended on on March 13, 2012. Just prior to his arrest, Keyes kidnapped, robbed, raped and murdered 18-year-old Anchorage resident, Samantha Koenig.

Keyes demanded a $30,000 ransom for the young woman after creating the illusion that she was still alive — even though he had dismembered her and thrown her body in Matanuska Lake north of Anchorage. Keyes led police to him by withdrawing money from the account where the ransom money was deposited, as well as using Koenig’s debit card across the Southwest.
