A man who had just helped move a broken-down vehicle was hit by an SUV and killed Monday night as he made his way across Enterprise Road in Mitchelville, authorities said.

The incident occurred just after 8 p.m. in the 3500 block of Enterprise Road, authorities said. Cpl. Larry Johnson, a Prince George's County police spokesman, said 78-year-old Willie Randolph Prince had just helped push a broken-down vehicle out of the roadway and was walking back across Enterprise Road toward a parking lot when he was struck by a 2004 Toyota 4Runner headed north. Prince, who lived in Mitchelville, was taken to a nearby hospital, where he was pronounced dead, Johnson said.

Johnson said the driver of the 4Runner remained on the scene and was “being very cooperative” with investigators. He said police do not believe alcohol was a factor in the crash, but they are investigating whether the 4Runner was speeding.

No charges have been filed in the incident.
