WOODBRIDGE, Va. — An Army staff sergeant assigned to the Pentagon was arrested on murder and other charges in the death of a police officer and another person, authorities said Sunday.

Ronald Hamilton, 32, 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 were hospitalized with injuries.

The suspect is an active duty Army staff sergeant assigned to the Joint Staff Support Center at the Pentagon, according to Cindy Your, an Army spokeswoman based at Fort Meade, Maryland.

The death of Ashley Guindon was just the latest tragedy to strike the family. Her father, David, committed suicide upon returning from Iraq, where he served with the New Hampshire Air National Guard.

“He came home and took his own life,” said Dorothy Guindon, Ashley’s grandmother.

She said Ashley was born in Springfield, Massachusetts. The family later moved to Merrimack, New Hampshire.

“This is really a shock to us,” Dorothy Guindon said. “Ashley was such a nice person.”
