A former Navy Seal who was riding a bike was killed in a collision with a car on Massachusetts Avenue in Bethesda.

Montgomery County police Capt. Paul Starks said that the victim was a 64-year-old man who had served as a Navy Seal. Police identified him as Timothy A. Holden of Bethesda.

About 6:30 a.m. in the 6000 block of Massachusetts Avenue, Holden was struck by a 22-year-old man driving a Chevrolet Malibu, police said. Part of the roadway there, between Sangamore and Goldsboro roads, was closed during the morning rush hour and has since reopened.

Starks said that Massachusetts Avenue has a dedicated bike lane in the area where the man was killed. He said investigators are trying to determine whether the biker was in the main vehicular lane, or whether the car that hit him was in the bike lane.

The driver remained at  the scene, authorities said.

“There’s a bike lane there. And being close to the District, it’s an area that I would say is frequently used by bikers, some of whom are commuting,” Starks said.
