WOODBRIDGE, Va. — A rookie police officer was killed and two others were wounded while responding to a domestic-related shooting Saturday night in the Washington suburb of Prince William County, Va.

Officer Ashley Guindon died from her injuries, according to the Prince William County Police Department. Another woman was reportedly found dead after police arrived at the scene. County authorities were said to be preparing a capital murder charge and other charges against a suspect identified as a military serviceman, who is in custody.

Identities of others involved in the incident, whether officers or civilian, have not been released.

Guindon had been sworn in to the Prince William County Police Department on Friday and began her first shift this weekend. She 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. He said he did not know the exact dates of when she started and left.

The Washington Post reported that Guindon was a graduate of ­Embry-Riddle Aeronautical University in Daytona Beach, Fla., who held a bachelor’s degree in aeronautics and had served in the U.S. Marine Corps Reserve.

The other officers are being treated at Inova Fairfax Hospital. Their conditions were unknown. At the hospital, where the three officers were flown by helicopter after the shooting, more than 100 patrol cars lined the roads outside early Sunday morning to stand vigil and escort Guindon’s body to the medical examiner, the AP reported.

Prince William County Commonwealth Attorney Paul Ebert said he has authorized capital murder and others charges against the suspect, the AP said.

The shooting occurred in the Lake Ridge neighborhood, on a curving street with $500,000 suburban houses with brick and siding exteriors, manicured lawns and two-car garages about a five-minute drive from the county office building.

Officers received a call around 5:30 p.m. ET Saturday in Woodbridge, about 30 miles southwest of the nation’s capital, about a “verbal argument,” Sgt. Jonathan Perok, spokesman of the Prince William County Police Department, told the AP.
