Jack Santos, played by Tommy Swerdlow, is a character from the film Child's Play.
Jack is Mike Norris' partner who was investigating Andy Barclay's babysitter's death. In the beginning of the first film, he was mostly the cop who drove Mike's car to chase Eddie Caputo in his van. He was also one of the police officers that believed Andy was the killer.
During the end, he tried to show Mike that Chucky wasn't alive, but was nearly killed by him and then he believed that the Barclays and Mike were telling the truth.
