Fairfax County Police are investigating after a 34-year-old man with a gun was shot and killed in front of his Centreville, Va., home.

The incident happened shortly after 1:30 a.m. in the 6100 block of Kendra Way. Fairfax County police were called to the home for a disturbance.

Once at the scene, Fairfax County police said the suspect approached them from his ground level garage armed with a gun. They say they told him to drop the weapon, but he refused and shots were fired. Police said it does not appear that shots were exchanged, but that will be a part of the police investigation.

Neighbors said the incident quickly unfolded and they heard two to three shots.

One neighbor said the man, identified as Ricardo Leon, was a Marine and fought in Iraq. She said he and his wife had been married for two to three years and moved into their Centreville town home when they were newlyweds. The neighbor described them as a happy couple and said they were preparing to celebrate their anniversary and were planning to start a family.

Leon's wife was the only other person inside the home. Police said she was not injured during the incident.

The four officers involved in the shooting are on routine paid administrative leave.
