WASHINGTON — Police say a driver struck a pedestrian who was walking on a sidewalk in Washington, D.C.

Metropolitan police said in a news release Friday that the driver, 37-year-old Roger Hector Hamilton, was charged with involuntary manslaughter and driving under the influence.

Police say a preliminary investigation revealed that the driver of a Mercury Mountaineer was traveling northbound when he lost control, mounted a curb and struck 42-year-old Vincent Childs. They say Childs was pronounced dead at the scene.

The Washington Post reports that police say the vehicle hit two trees and that the driver attempted to flee. However, a bystander stopped him and held him until he was placed under arrest.

An arrest affidavit says the suspect failed a sobriety test. It’s unclear if Hamilton has a lawyer.
