A woman bicycling on Wisconsin Avenue near the Capital Beltway in Bethesda early yesterday was struck by an automobile and killed, and a Mount Rainier man was later arrested and charged with homicide by a motor vehicle while intoxicated, Montgomery County police said.

The woman had not been identified as of yesterday evening.

Police said the cyclist was riding southbound in the right lane on Wisconsin Avenue between Pooks Hill and Alta Vista roads shortly before 1 a.m. when she was struck by an automobile as it was passing a car on the right.

Witnesses told police that the impact threw the woman onto the hood and through the windshield of the automobile. The automobile continued for almost half a mile before it was driven into a parking lot. There the driver put the woman on the ground and drove off, police said.

The woman was pronounced dead at the scene, said Ann Evans of the Montgomery police.

Police said witnesses gave them a description of the automobile and a partial license number. Based on that information, they stopped a 1979 Pontiac Bonneville on Commerce Road, a few miles from the scene.

Evans said that David L. Henry, 24, of 3330 Buchanan St., Mount Rainier, was charged with homicide by a motor vehicle while intoxicated, manslaughter, driving while intoxicated, personal injury hit and run, and failure to control speed to avoid a collision. He posted $5,000 bond yesterday and was released.

If Henry is convicted of all charges, he could be sentenced to a maximum of 15 years in prison and fined $250, Montgomery County officials said.
