On a quiet Tuesday morning in January 1974, Dennis Rader broke into a Wichita home and killed Joseph Otero, his wife Julie, and two of their children. The crime scene told investigators everything — and nothing. Every victim had been bound. The killer had brought his own cord. Nothing of value was taken. Wichita police had never seen anything like it, and they had no suspect.

This episode covers the opening chapter of one of America's longest unsolved serial murder cases. We examine the Otero family — who they were, how they came to be in Wichita, and why they became targets. We trace Rader's own background: a man who had served in the Air Force, recently returned to the city, and had been fantasizing about binding, torturing, and killing since adolescence. He called it his 'factor X.'

Months after the murders, a letter appeared inside a library book, signed with an acronym Rader had invented for himself: BTK — Bind, Torture, Kill. It was the beginning of a decade-long correspondence with police and media that mixed operational detail with grotesque vanity. He wanted recognition. He wanted Wichita to know his name.

We also look at the double life that made him invisible: compliance officer, church president, Cub Scout leader. Rader understood that respectability was camouflage. His positions gave him authority, access, and cover — and for thirty years, it worked.

Ten victims. Seventeen years of killing. Then silence, until a floppy disk ended everything.
