The BTK Serial Killer Asked Police If They Could Trace Him If He Sent A Floppy Disk, And He Believed Their Answer

For over 30 years, Dennis Rader terrorized Wichita, Kansas, as the BTK serial killer. His victims ranged in age and gender, as did the timing between his crimes. Ever elusive, the former ADT security system employee, Lutheran church president, and local Boy Scout den leader would bind, torture, and kill (BTK) innocent people after he had stalked them to learn their daily routines and found ways to enter their homes. Once the crime was committed, Rader made sure the public knew about each murder by alerting newspapers with details of the gruesome events and sending taunting gifts related to each offense to the local police station. Rader remained elusive and anonymous until 2004, when he had grown tired of not receiving more publicity for his actions. After sending in puzzles with information regarding his 10 victims, dolls tied in a similar way to those who were slain, and a portion of his autobiography without much news coverage, the impatient Rader sent a letter to police inquiring about the traceability of computer technology. In it, Rader wrote: Can I communicate with Floppy [disk] and not be traced to a computer. Be honest. He then requested the police file an ad in the local newspaper with the phrase, “Rex, it will be OK," if the response was yes. Ater authorities placed an affirmative response in the paper, a local news station received a floppy disk from the murderer - and the police began to analyze the metadata encrypted in the files. From the disk, law enforcement traced the user to a man named “Dennis” at Christ Lutheran Church, where Rader had used a church computer to produce the evidence. A quick search in the church's directory pointed to a man named Dennis Rader. Upon arriving at Rader's home to question him regarding the disk, police found a black Jeep Cherokee that matched earlier footage of the killer dropping off a package of evidence. After DNA testing, the family man was accused of and convicted for all 10 suspected murders. According to interrogating officer Lt. Ken Landwehr, Rader was astounded that the police had lied to him in order to crack the cases, exclaiming: I need to ask you, how come you lied to me? How come you lied to me?
