"There's been a domestic situation between the husband and wife," Sheriff Jenkins said. "Our investigation, up to this point, would lead us to believe the crime was committed by one of the adults. Right now that focus is on Mr. Washington himself."
The children were ages four, six and 13 years old, Sheriff Jenkins said. Their names have not been released.
"Sheriff units remain on scene at this time, and are being assisted by the Virginia State Police collecting evidence," a Sheriff's Office spokesman said.
Deputies went to the Rixeyville Road home when family members of the female victim grew concerned when she did not show up for church on Sunday.
This is a developing story.
