29-year-old Officer Ashley Guindon shot dead after she answered a domestic violence call at a Virginia home on Saturday - her first day on the job.
An Army staff sergeant assigned to the Pentagon has been charged with shooting dead a rookie police officer on her first day and his wife.
Ronald Hamilton, 32, is being held without bond accused of shooting dead 29-year-old Officer Ashley Guindon after she and two coworkers answered a domestic violence call at his home on Saturday evening.
According to an affidavit, Hamilton's wife Crystal, 29, called police begging for help at 5.30pm.
By the time Guindon arrived with her field officer Jesse Hempen, 31, and ten-year police veteran David McKeown, 33, Crystal was shot dead, the affidavit states.
Hamilton allegedly opened fire as soon as the officers arrived, fatally shooting Guindon and wounding the other two. The Hamiltons' 11-year-old son was in the house at the time but survived unscathed.
On Sunday, police chief Stephen Hudson paid tribute to Guindon's work and gave a poignant account of the passion she showed when she interviewed for the job.
Crystal Hamilton's sister also paid tribute to Guindon as she thanked the police force for their attempts to apprehend the suspect. 'Most importantly, the officer who sacrificed her life for my sister and my nephew,' she told ABC7.
Ronald Hamilton, 32, is being held without bond accused of shooting dead 29-year-old Officer Ashley Guindon after she answered a domestic violence call at his home on Saturday - her first day on the job.
The suspect is an active duty Army staff sergeant assigned to the Joint Staff Support Center at the Pentagon, according to Cindy Your, a Defense Information Systems Agency 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 the day after he returned home from Iraq in 2004, where he served with the New Hampshire Air National Guard. He was buried with full military honors on August 26 that year.
'He came home and took his own life,' said Dorothy Guindon, Ashley's grandmother.
Ashley was his only child.
Ashley was born in Springfield, Massachusetts. The family later moved to Merrimack, New Hampshire, according to her grandmother.
'This is really a shock to us,' Dorothy Guindon said. 'Ashley was such a nice person.'
Officer Brandon Carpenter, at the county's adult detention center, says Hamilton is being held without bond at the jail on charges that include murder of a law enforcement officer, first-degree murder, two counts of malicious assault and two counts of use of a firearm during a felony.
Hamilton is scheduled to be arraigned Monday morning.
Prince William County Commonwealth's Attorney Paul Ebert told The Associated Press on Sunday morning that the gunman's wife was the victim in the domestic incident. He did not provide her name.
The shooting occurred Saturday evening at Hamilton's home in Woodbridge, where neighbors say he lived with his wife and their son.
Guindon had a degree in aeronautics from Embry-Riddle Aeronautical University and a master's degree from George Washington University in forensic science.
She served in the military from 2007 to 2013 as a corporal in the U.S. Marine Corps.
Prince William County, where Woodbridge is located, is a suburb 30 minutes outside Washington, D.C., and has a relatively low crime rate.
Guindon had been a county police officer a few years ago and had left and returned to the force, Corey Stewart, chairman of the Prince William County Board of Supervisors, said in a phone interview with The Associated Press on Saturday night.
