Garland police have released new video showing the hit-and-run crash that killed a 46-year-old woman Thursday.
Officers responded about 11:45 p.m. to Jupiter Road and Forest Lane, where Joyce Cawis was found unconscious inside a light-colored Toyota 4Runner.
Cawis of Rowlett was taken to a local hospital, where she died, police said.
Investigators think a black, four-door Ram Big Horn pickup was traveling north on Jupiter at a high rate of speed and hit the 4Runner that was going west on Forest.
The latest news from around North Texas.
The video released Sunday by police shows the moment the two vehicles collide in the intersection.
Witnesses said they saw the driver of the Ram get out of the truck and then into a black car shortly after the crash without rendering aid.
Investigators are trying to locate the driver of the Ram who witnessed described as a Hispanic man with a short fade haircut. He may have been wearing a black soccer-style jersey with white writing on the front and back, black shorts and leggings.
Monday, police said investigators had identified the driver of the Ram as Edgar Alfonso Ugalde. Police issued an arrest warrant for failure to stop and render aid.
