The Wythe County Sheriff's Office is investigating an apparent murder-suicide in the town of Rural Retreat in Wythe County.

According to W. Keith Dunagan, a woman discovered the bodies of her parents Peggy Ann Cook, 72, and Curtis M. Cook, 76 in their home on the 700 block of Murphyville Road in Rural Retreat around 6 p.m. Wednesday evening.

According to the Sheriff's Office, their preliminary investigation has determined that Curtis Cook shot Peggy Cook in her head before shooting himself at their home.

Sheriff Dunagan explained investigators have not pinpointed what led to the shootings.

"We have not been able to find any motive at all, we've talked to the family, they say they'd done nothing to indicate that he would do something like that ever."

In the more than five years the couple lived in their home, the sheriff's office had never been called to the home before Wednesday night, Dunagan said.

"The family told us they squabbled a little bit but there was never any physical violence between them."

Neighbors are just as puzzled as family members as to what happened.

"They didn't see anything that would suggest he would do something like that," Dunagan said.

Dunagan explaiend there is no need for public safety concerns because of the incident appears to be a murder-suicide.

"We are not looking for anything else at this time, we do have some things we've requested from the ME's office, to test as evidence for us, just to make sure,' he said.

"But it's not like anybody is running loose, people don't have anything to worry about like that."

The bodies have been taken to the Medical Examiner's Office in Roanoke for an autopsy.

State Police is assisting with the investigation.
