A Virginian shooter who allegedly killed his wife and a young police officer has been identified as an active duty Army staff sergeant assigned to the Joint Staff Support Center at the Pentagon, authorities say.

Ronald Williams Hamilton, 32, is accused of killing Prince William County Police Officer Ashley Guindon and shooting two other police officers as they came to his house Saturday afternoon after answering a domestic call, according to county police.

He surrendered to backup officers who arrived after the three officers were shot and found a dead woman, an 11-year-old boy and two used guns.

Crystal Hamilton, 29, was found dead in the house and later identified as the shooter's wife.

"The investigation revealed that the accused and his wife were involved in a verbal altercation which escalated physically," he said. "The wife was able to contact police; however, before officers could arrive, she was allegedly shot and killed by the accused."

According to Hudson, two other shot officers had non-life threatening injuries, however still on "a long road ahead" before fully recovering.

Hamilton is being held without bond on charges of capital murder of a police officer and is scheduled to be arraigned Monday.

There is a probability that Hamilton will receive the death penalty on charges of capital murder of a police officer, and first-degree murder however the decision rests with the court to decide, according to Commonwealth Attorney Paul Ebert.

Besides two counts of murder, Hamilton is charged with two counts of malicious wounding of a police officer and two counts of use of a firearm in commission of a felony.
