Four people have been found shot to death along a highway in a North Carolina business research park.
The Durham County Sheriff's Office says the bodies of three women were found early Saturday in a car on N.C. Highway 54 in Research Triangle Park, while the body of a man was outside the car. Lt. Stan Harris says the shootings weren't random, but he said he couldn't disclose any other details.
Officers responded after receiving a call just before midnight of shots being arrived. Harris says that when officers arrived, the victims' car was the only one on the road.
The bodies were at the state Medical Examiner's Office on Saturday. Authorities had not released the victims' names because the families hadn't been notified.
The Research Triangle Park is a 7,000-acre research and development park. It's home to more than 170 global companies that employ about 48,000 workers. Companies located there include IBM, Cisco and Credit Suisse.
