Two pedestrians were struck, one of them fatally, in a hit-and-run crash in Gaithersburg early Wednesday morning that police say they are investigating as a homicide.

Montgomery County Police said the men were hit shortly after 1 a.m. in the 200 block of West Diamond Avenue.

One victim, a 34-year-old man, died at the scene. The other victim, a 54-year-old man, survived the crash and is being treated at a local hospital for non-life threatening injuries.

The victims are brothers, police said.

The surviving victim told police that he and his brother had received a ride from people in a black Honda Civic earlier Wednesday morning. They were dropped off near the Gaithersburg Plaza at Route 355 and Chestnut Street and struck by a car while walking west on West Diamond Avenue.

Police would not say where the ride began.

The surviving victim said he believes the car that hit them was the same one that had given them a ride, police said.

Officers located a black Honda Civic in a nearby shopping center and police believe this is the car involved in the crash. Police said the car was unoccupied and has damage consistent with a pedestrian collision.

Police are looking for the driver of the car but have not said who the car is registered to or released any suspect information.

The relationship between the victims and the occupants of the car remains unclear, and police would not say whether the Honda was reported stolen.

Anyone with information about the crash can call 240-773-5070, 1-866-411-TIPS (8477) or submit a tip online.
