United States v. Valle was a criminal case in the Southern District of New York concerning Gilberto Valle, a New York City Police Department officer who had discussed on online fetish chatrooms his fantasies about kidnapping, torturing, raping, killing, and cannibalizing various women he knew, and had used a police database to find the addresses of some.

Dubbed the "Cannibal Cop" by the media, Valle was convicted by a jury of conspiracy to commit kidnapping and, for the use of the police database, violations of the Computer Fraud and Abuse Act (CFAA).

The case drew widespread attention for its unusual nature and for the question it posed of at what point exploration of dark fetishes becomes criminal conspiracy.

[7] Valle joined the New York City Police Department in 2006, and was assigned to the 26th Precinct in Morningside Heights, Manhattan.

[9] He chatted with 24 other users about kidnapping, raping, torturing, killing, and cannibalizing more than 100 women, including his wife.

[15] Judge Paul G. Gardephe of Federal District Court overturned Valle's conviction on the conspiracy charge in June 2014, saying the evidence supported his contention that he was engaged in only "fantasy role-play".

In November, the judge ended Valle’s home confinement, sentencing him to time served and one year of supervised release, including mental health treatment.
