Don’t Take OPSEC Advice From the Police
This is a rather hilarious story about how a serial killer was apprehended. The BTK Killer spent quite a bit of time sending gloating letters to the police.
In his letters to police, Rader asked if his writings, if put on a floppy disk, could be traced or not. The police answered his question in a newspaper ad posted in the Wichita Eagle saying it would be safe to use the disk. On February 16, 2005, he sent a floppy disk to Fox TV station KSAS in Wichita. Forensic analysis quickly determined that the disk had been used by the Christ Lutheran Church in Wichita, as well as a reference to the name “Dennis”. An internet search determined that a “Dennis Rader” was president of the church council. He was arrested on February 25.
