Paul John Knowles (April 17, 1946 December 18, 1974), also known as The Casanova Killer, was an American serial killer tied to the deaths of 18 people in 1974, though he claimed to have taken 35 lives. Born in Orlando, Florida, his father gave him up to live in foster homes and reformatories after he was convicted of a petty crime. Knowles himself was first incarcerated at the age of 19, and in the years following he spent more time in prison. In early 1974, Knowles was serving time at Raiford Prison in Florida (now known as Florida State Prison) when he began corresponding with a divorcee in San Francisco named Angela Covic, who made a trip to the prison to visit Knowles. Upon her arrival, Knowles proposed to Covic. After she accepted his proposal, she became instrumental in getting Knowles released from prison by paying for his legal counsel. Upon his release, Knowles flew directly to California to be with her.
