Chris Watt’s ‘Pen Pal’ explains the sick fetishes that drove him to murder

Crime writer Cherlyn Cadle took a special interest in Watts and tried to understand what drove the devoted father to destroy his family and his life. So the 72-year-old began exchanging letters with him, and while the exchanges started cordial, Watts soon shared his sexualized details and desires with her.

“He told me dark, sexual things he did with his mistress,” Cadle told the newspaper Daily mailreferring to Watts’ secret lover Nichol Kessinger. “There were a lot of things you wouldn’t tell your mother, but he told me.”

Cadle said Watts bragged that he and Kessinger had sex three to four times a day, describing his libido as “insatiable.” He also said they would talk on the phone for hours, and she would send him naked pictures.

Above all, Kessinger would perform actions that his wife would not do.

“A lot of it is stuff that I’m just not going to repeat,” Cadle explained. “But his relationship with her was very sexual, very twisted, very confused. And that’s part of the reason why I believe he did what he did.”
