Kathleen Cooke Mangan, Wife Of 'Cannibal Cop' Gilberto Valle, Reportedly Turned Him In

The estranged wife of accused "cannibal cop" Gilberto Valle reportedly turned him in, a law enforcement source told the New York Post.

Valle's wife, Kathleen Cooke Mangan, a school teacher, contacted the FBI after reportedly finding "weird stuff" on her husband's computer last month. This included the "names, photos, dates of birth, heights, weights and bra sizes of dozens of women," as well as a detailed "tactical plan" to abduct, rape, kill, cook and eat victims, according to Gothamist.

Upon discovering the plan, Mangan immediately fled the state, taking the couple's young daughter with her.

“When she saw what was on the computer, what he was into, she literally ran out of the house with just the clothes on her back,” a law-enforcement source told the New York Post.

Valle's public defender initially argued that the officer be released on bail, adding he was guilty only of a "deviant fantasy," but the claim was denied.

According to the criminal complaint against him, Valle allegedly told a co-conspirator that he looked forward to "getting off" by knocking out and tying up the women -- many of whom he claimed he knew personally or had met through OkCupid.

His so-called "blueprint" described a torture method in which he would cook a woman "over a low heat, [keeping] her alive as long as possible." Valle allegedly conspired with three other cannibal fetishists over the Internet.
