The police officer recorded details like the woman’s date of birth, height, weight and bra size. He made note of certain materials, like chloroform and rope.

And then the officer, Gilberto Valle, a six-year veteran of the New York Police Department, created a document on his computer, calling it a blueprint for “Abducting and Cooking.” In one of the most disturbing and unusual arrests involving a police officer, agents with the Federal Bureau of Investigation took Officer Valle into custody on Wednesday after they uncovered several plots to kidnap, rape, cook and eat women.

“I was thinking of tying her body onto some kind of apparatus,” he wrote to a co-conspirator in one electronic communication recovered by law enforcement authorities. “Cook her over a low heat, keep her alive as long as possible.”

When the co-conspirator asked how big the officer’s oven was, Officer Valle replied, “Big enough to fit one of these girls if I folded their legs.”
