Prince William County police mark 2-year anniversary of Officer Ashley Guindon's death

The Prince William County Police Department is marking the two-year anniversary of one of their officers being shot and killed in the line of duty during her first day on the job.

Officer Ashley Guindon was shot and killed while responding to a domestic dispute at a home in Woodbridge on Feb. 27, 2016.

The 28-year-old rookie officer, who was a U.S. Marine Corps Reserve, had just been sworn-in for duty the day before. Two other officers, including her training officer, were wounded but have since recovered and returned to duty.

Ronald Hamilton, a 32-year-old active-duty Army staff sergeant assigned to the Joint Staff Support Center at the Pentagon, was arrested in Guindon's death. Officials said Ronald Hamilton also shot and killed his wife, 29-year-old Crystal Hamilton. He was charged with capital murder, first-degree murder, two counts of malicious wounding of a police officer, and three counts of use of a firearm in the commission of a felony.

The Prince William County Police Department tweeted, "May we never forget the brave heroes who have given the ultimate sacrifice and the courage they have shown. 'In valor there is hope.'"
