A 47-year-old man is dead of severe head trauma following a confrontation over a car crash on the Belt Parkway in Queens early Sunday, cops said.

Police responding to an assault in progress found Crisaine Dockery unconscious on the Belt Parkway at Farmers Blvd. at about 1:15 p.m., cops said. A second man, 39, suffered minor injuries to his arm, police said.

Medics took Dockery, of St. Albans, to Jamaica Hospital, but he couldn’t be saved. An NYPD spokeswoman couldn’t say Sunday how he sustained his injuries, but police sources said he was involved in a crash before he was hurt.

Police are referring to his death as a homicide.

Cops were looking for two people who fled the scene, one of whom wore a black tracksuit with a stripe on the pants.

Cops have made no arrests.
