A hearing is under way at Fort Knox for a soldier who is accused of fatally shooting a civilian worker at the central Kentucky Army post.

The Article 32 hearing began Wednesday for Sgt. Marquinta Jacobs and was expected to conclude on Thursday. The hearing is similar to a grand jury proceeding in a civilian court, but the defendant is allowed to be present.

Jacobs is charged with murder in the April 3 death of 51-year-old Lloyd Gibert, who worked at the Human Resources Command building.

An eyewitness to the shooting testified Wednesday that he was walking with Gibert when Jacobs approached them, asked whether Gibert was having an affair with his wife, and then began shooting him.

Investigators say Jacobs fired eight shots at Gibert before fleeing the scene.
