(WSB Radio)  A man pulled over during a routine traffic stop in Atlanta is being questioned about his alleged involvement in a double murder in Carroll County.

The bodies of a man and a woman were found overnight in a home in the Peek Squire Estates in Carrollton.

"We couldn't make contact with anyone at the house," says Carroll County Sheriff's Captain Shane Taylor.  "We checked around the perimeter of it, looking for anything out of place.  We then observed a body inside the residence."

The suspect was stopped in Atlanta for a traffic violation.  That's when police learned about the murders.

"They were involved in a traffic stop in which the subject had some weapons on him," Taylor says.  "He advised them (the officers) that he had committed a double homicide in our jurisdiction."

Investigators are working to determine a motive and identify the victims. 

Authorities are not releasing the suspect's name.
