E26: “The Casanova Killer” Pt. 2 – Paul John Knowles

A lust killer who dreamed to be known as an outlaw, Paul John Knowles sought infamy. He was so desperate to be remembered; he recorded his own confession to multiple murders while still a free man, and shared the tapes with his lawyer.

Alexander Pichushkin’s favorite book was How to Win Friends and Influence People, which he used to charm his victims into following him into the woods. He was charged with 49 murders, but was upset the authorities didn’t verify a higher kill count.

Greg and Vanessa examine how Pichushkin’s desire for validation was the only reason he was caught.
