The estranged wife of New York’s so-called Cannibal Cop took to the witness stand yesterday, on the first day of her estranged husband’s conspiracy to kidnap trial.

Kathleen Mangan-Valle described how former NYPD officer Gilberto Valle planned to tie her up by her feet, then slit her throat and “watch the blood rush” from her body.

She went on to say how she discovered her husband’s alleged plot to “slow cook” and eat over 100 women after finding graphic emails on his computer.

She also claims to have found images of naked, blood-soaked women on the computer, some of whom she believes were dead.
