Video has emerged showing one of two fatal drive-by gang-related Queens shootings that investigators have linked to each other.The startling surveillance video shows the Monday afternoon shooting death of 21-year-old Hutchinson as he sat in a Dodge Charger on Springfield Ave. and 140th Ave. in Laurelton.A white vehicle rolled up and someone in the front passenger seat lowered their window and opened fire, getting off six shots before being driven away, the video shows.Hutchinson, hit multiple times in the chest and buttocks, was rushed to Jamaica Hospital, where he died.The two other people in his car were uninjured, police said.Hutchinson has a criminal record and was suspected of robbing someone earlier that day, sources with knowledge of the case said. Police were looking into whether his killing was payback for that heist.A witness to Hutchinson’s killing, Antoine Folkes, 23, a reputed member of the Queens-based SNOW Gang, was fatally shot on a Rosedale street Monday night, sources said. He and another victim, Marcellus Shields, 21, died at the scene, sources said.Detectives were hoping to interview Folkes about Hutchinson’s death when he was killed, sources said.No arrests have been made in either case.
