The Webbers were found on a bed in an upstairs bedroom, and Swartwood said investigators, assisted by a county coroner and a member of the Eastern Panhandle Drug and Violent Crime Task Force, removed possible evidence from the home.
An autopsy also has been requested, Swartwood said.
Exactly when the couple might have been shot or the possible circumstances of their deaths were not released by police, but neighbors said Saturday that they heard what might have been gunfire on Friday between 7:30 and 8 p.m. They saw police carry two weapons from the home, and watched officers collect evidence below an apparent bullet hole on the west side of the house.
"I'm still shocked and distressed about it," Barbara Teasley of 706 W. King St. said nearly six hours after police arrived at the scene.
"It's the kind of thing that doesn't happen every day - thank God," Teasley said while holding a plate of brownies she was taking to a neighbor's house for a social gathering Saturday night.
Teasley and other neighbors said the couple had a teenage boy who was learning to drive and a younger daughter.
When they first moved in about two years ago, Teasley said their vehicle, an old police car, had Pennsylvania plates.
"(They) said they were doing police work," Teasley said.
She didn't believe them.
Nearby Porter Avenue resident Gail Webber said she heard a "loud boom" Friday night. Webber didn't know the couple's last name until being interviewed, but didn't believe she was related to the couple.
Neighbors said the Webbers stayed to themselves, even the children, but often saw the couple riding a Harley-Davidson together.
