Stafford County Sheriff's Office investigates fatal shooting

A man shot and killed his estranged wife inside a Stafford County home Friday afternoon, authorities say, but no charges have yet been filed.

The shooting happened just before 2:45 p.m. Friday on Alderwood Drive in Stafford, county sheriff officials say. Julie Serna, 42, was found in her estranged husband's home suffering from gunshot wounds. The mother of two boys died at an area hospital.

Serna's husband is an instructor at the FBI National Academy at Quantico. No charges have been filed against him at this time.

Neighbor Katie Duncan said, "The fact that she is not here is ridiculous for them to say, 'Oh, well here, let me slap on your wrist."

The mystery over exactly what happened inside the home now haunts neighbors. They say the couple was separated, and Serna went to the home after lunch with a neighbor to let the family dog out.

"I watched them bring the victim out of the house on stretcher...," Duncan said. "They took her to the ambulance."

Local media in Las Cruces, New Mexico, where Serna grew up, report police there received a 911 call from a man saying he had just shot his knife-wielding wife. But when emergency crews showed up at the New Mexico address, they discovered it was the husband's previous home. He hadn't updated his computer service provider with the Stafford address.

New Mexico 911 dispatchers reportedly notified Virginia authorities.

Serna's best friend, Donna Ulibarri-Peralta, spoke with ABC7 on the phone from New Mexico.

"I told her I was frightened for her. I had a nightmare and that I was very frightened for her. I told her be careful with him," said Ulibarri-Peralta.

Authorities say it remains an active investigation.
