Court records show an Army staff sergeant has admitted shooting his wife and three police officers who showed up at his front door after his wife called 911.

One of the officers, Ashley Guindon, died from her injuries in Saturday's shooting. Guindon had just been sworn in and was working her first shift.

Thirty-two-year-old Ronald Hamilton, of Woodbridge, is charged with capital murder in Guindon's death. He also faces a murder charge in the shooting death of his wife, 29-year-old Crystal Hamilton.

Ronald Hamilton made initial court appearances Monday in Manassas and is being held without bond. An affidavit filed Monday in General District Court states Hamilton told police that he shot his wife and the three officers.

The other two officers were hospitalized and are expected to survive.

An Army staff sergeant charged with killing his wife and a northern Virginia police officer who was on her first day on the job is set to appear in court.

An arraignment is scheduled for Monday for 32-year-old Ronald Hamilton, a Pentagon worker. Commonwealth's Attorney Paul Ebert has said he'll likely seek the death penalty against Hamilton, who is being held without bond on charges including capital murder, first-degree murder and malicious wounding.

Prince William County Police Chief Stephan Hudson says Hamilton and his wife, Crystal, had been arguing all day Saturday, but it escalated after she called 911. He says Hamilton fatally shot his wife and then fired at the arriving officers, killing Officer Ashley Guindon and seriously wounding two others before he surrendered.
