The founder of an extreme fetish website used by New York's "cannibal cop" testified Tuesday that online chats about women being eaten were a typical fantasy and compared his forum to Facebook. Sergey Merenkov, the first witness called by suspended policeman Gilberto Valle's defense team, told the court his site darkfetishnet.com, a favorite of the accused, was "a social network." "It's very similar to Facebook," said the Russian in videotaped evidence.
