The Virginia man facing murder charges in the shooting deaths of a police officer and another person has been identified as an Army staff sergeant assigned to the Pentagon.

Ronald Hamilton is being held without bond in the Prince William County Adult Detention Center on charges that include murder of a law enforcement officer. He is accused of shooting and killing Officer Ashley Guindon after she answered a domestic violence call at the Hamilton home Saturday evening. Two other officers are undergoing treatment at a hospital.

Cindy Your, a Defense Information Systems Agency spokeswoman based at Fort Meade, Maryland, said Hamilton is an active duty Army staff sergeant assigned to the Joint Staff Support Center at the Pentagon.

Hamilton faces arraignment on Monday.
