CHILLING KILLER CONFESSIONS

The true nature of their crimes were laid bare when they explained their actions

DENNIS RADER

Between 1974 and 1991, Dennis Rader, known as the BTK serial killer, bound and strangled at least 10 people to death in the Wichita area of Kansas, US.

Before his arrest in February 2005, Rader taunted police by sending anonymous letters and pictures of his victims to investigators. And while Rader eluded the police for nearly three decades, he was eventually caught thanks to metadata on a floppy disk he'd sent to a local television station, as well as DNA obtained from his daughter Kerri Rawson.

After his arrest, Rader confessed to his shocking crimes in a lengthy, graphic court statement and explained his reasons for killing one family with chilling disregard.

“I didn't have a mask on or anything. They already could ID me, and [I] made a decision to go ahead [and] put 'em down, I guess, or strangle them,” he said about his decision to kill Joseph and Julie Otero as well as two of their children after breaking into their house in 1974.

In 2005, the now 80-year-old was sentenced to 10 life terms in prison.
