The Cub Scout leader who sent a floppy disk that cracked a 31-year murder case

The Cub Scout leader who sent a floppy disk that cracked a 31-year murder case

A floppy disk arrived at a Wichita television station in 2005.

It was part of a series of communications from someone calling himself BTK — Bind, Torture, Kill.

The case had gone cold for decades; the last known killing was in 1991.

Police examined the disk's metadata, the hidden digital records of where a file was created and edited.

That metadata pointed to a computer at Christ Lutheran Church.

The man who would become the suspect was president of that church's council.

He was a married father of two.

He was a Cub Scout leader.

He was a public face of ordinary life, a man who worked as a compliance officer for Park City, Kansas, and had once installed security systems for ADT.

Not because the disk alone solved anything.

Because the disk was one step in a chain.

A subpoena for church records identified him.

DNA evidence from crime scenes later matched him.

The record does not establish that the metadata alone cracked the case.

The record shows the metadata led to a church computer, then a subpoena, then DNA confirmation.

How does a church council president become BTK?

How does a Cub Scout leader spend decades as a killer?

How does a man with a wife and two children hide ten murders?

That would require evidence, and the evidence came one piece at a time.

The disk was a piece.

The subpoena was a piece.

The DNA was a piece.

The man was arrested on February 25, 2005.

He was charged with ten counts of first-degree murder.

THE PROJECTS — 1974 TO 1991

Between 1974 and 1991, Dennis Rader murdered ten people in and around Wichita, Kansas, in killings he later called his "projects."

His first known victims were a family of four — a father, mother, and two children — killed in their home on January 15, 1974.

He continued with six more victims: one in 1974, two in 1977, one in 1985, and one in 1991.

The specific details of each killing are not in the record beyond the dates and the family of four; the source does not describe the crime scenes.

Rader taunted police and media with letters and cryptic clues, adopting the self-given nickname "BTK" for Bind, Torture, Kill.

Early leads went nowhere; Rader was questioned in 1974 but was not considered a suspect.

He had previously worked at ADT Security Services, which gave him access to homes.

The letters were a taunt. The clues were a game. The nickname was a boast.

That would require evidence.

The case went cold for decades. The projects stopped in 1991.

Then, in 2004, the letters resumed.
