Mike was last seen in his UCLA Dykstra Hall dorm room in Los Angeles, CA. He had been playing a computer video game, competing against a friend in another room through an intranet connection. When the game was over, about 4 a. m. , he signed off, went outside his room and congratulated his friends he had been playing against. The two then turned and went back to their rooms. No one can remember seeing Negrete after that. Investigators found his wallet, his keys and his shoes in the dorm room.
