A judge convicted a Hyattsville man in a hit-and-run crash along the Baltimore-Washington Parkway that killed a District man and injured his fiancee, prosecutors announced Wednesday.

Earl Howard Teeter, Jr., 73, was found guilty of “operating a vehicle without due care” in the Feb. 1 crash that killed Rick Warrick, 38, who was changing a flat tire at the time of the collision, according to a statement from the United States Attorney for the District of Maryland and U.S. Park Police.

The incident began when Warrick had pulled his Hyundai to the shoulder of the parkway near Laurel and turned on his hazard lights to change a tire at about 9 p.m., police said. Shortly after that, Teeter’s van hit Warrick.

Teeter told authorities that he hit something when he changed lanes but didn’t know what he had struck, prosecutors said. Investigators seized his car from an auto-body shop after finding pieces of his dark-blue Toyota Sienna at the scene of the crash.

Teeter, who later turned himself into authorities, already pleaded guilty “to failing to stop after driving a vehicle involved in an accident resulting in death,” prosecutors said.

Teeter faces up to a year in prison and is scheduled to be sentenced in January.
