A man has been charged with murder in the shooting death of a civilian employee at Fort Knox.

A Thursday federal court filing by the FBI says Marquinta E. Jacobs fired a .45-caliber handgun at the victim, "striking him several times." It says a witness saw the Wednesday shooting after Jacobs and the victim had a verbal exchange in the parking lot of the Army Human Resources Command building on the post at Fort Knox.

Investigators found eight shell casings at the scene.

A criminal complaint filed in U.S. District Court Thursday says Jacobs fled to his mother's house in Portland, Tenn., but he was not there.

Fort Knox officials said a suspect wanted for questioning was apprehended Thursday in Portland. They identified the suspect as a Fort Knox soldier.
