The victim told police he was sitting in his vehicle at the fuel pump when his door opened.
The victim told officers that he felt there was another person behind him and turned around. He observed Perez standing near the rear of the vehicle holding a knife in his left hand.
According to court documents, Perez told the victim that "we need your [expletive] car."
An unknown woman approached in an attempt to divert his attention when a man, later identified as Bernardo Perez moved towards him.
