A family member discovered the bodies of the two adults, both 35, and three school-aged children Sunday night, according to the Culpeper County Sheriff's Office.
The shootings are being treated as homicides, with the Virginia State Police assisting, Detective Angela Deavers with the Culpeper County Sheriff's Office said. Deavers said she did not have other details, and the state agency confirmed only that it is assisting.
The three-bedroom house sits on about an acre of land just outside the town limits of Culpeper, according to Culpeper County property records. Culpeper, a town of about 15,000 people is known for its quaint downtown and Civil War history.
"This is definitely a shock to the community, for sure," Culpeper Mayor Michael Olinger said. "Very seldom do we have a murder in Culpeper or any kind of activity such as this." He said he did not know the victims.
