Clark County detectives are looking for a man they believe hit a pedestrian in his car, then fled, leaving the victim seriously injured on the side of a Vancouver road.

Joshua Allen Johnson

Detectives believe Joshua Allen Johnson, 31, was driving the red Nissan Sentra that hit a 34-year-old walking along the shoulder of Northeast 54th Avenue near Road's End Neighborhood Park in the early morning hours of Feb. 20, said Sgt. Fred Neiman, a spokesman for the Clark County Sheriff's Office.

A passerby found the pedestrian by the side of the road with serious injuries, Neiman said.

Media reports have identified the pedestrian as Paul Adams of Vancouver.

Johnson is 5 feet 8 inches tall and weighs 175 pounds, Neiman said. He has brown hair and brown eyes.

A warrant has been issued for Johnson's arrest for felony hit and run charges, Neiman said.

Johnson's location is unknown, Neiman said. Authorities ask anyone with information about his whereabouts to call 911 or email Detective Todd Young at Todd.Young@Clark.Wa.Gov.
