A woman and a child were found fatally shot Friday evening in a house in Fauquier County, Va., and police said hours later that they were still searching for a suspect.

In addition to the two deaths, a third person was injured at the house in the Midland area, the sheriff’s office said.

The matter came to law enforcement attention about 6 p.m., when a caller said that on arriving home he found his wife and a 6-year-old boy dead of apparent gunshot wounds, the sheriff’s office said.

According to the sheriff’s office, the home is in the 12000 block of Elk Run Road. The sheriff’s office said a 17-year-old male relative confronted the caller and fired several shots.

The wounded man left his house and called 911. He was taken to an emergency room by rescue personnel.

After surrounding the house and trying to contact the alleged assailant, the sheriff’s office said, law enforcement personnel entered the house about 10:15 p.m. But, they said late Friday, their search for an assailant was continuing.

Residents of the area were advised by the sheriff’s office to shelter in place.

The person being sought in connection with the incident was described by the sheriff’s office in a Facebook posting as a white male with short purple hair.

He was 5 feet 9 and weighed 125 pounds, the sheriff’s office said. No description of clothing was available.
