The Durham County sheriff says a man killed three women and himself in a car near a North Carolina business park.
Durham County Sheriff Worth Hill told The News & Observer of Raleigh on Sunday that investigators have a theory on what led to the shootings early Saturday in Research Triangle Park near Durham but aren't ready to release it. Details were scarce.
Authorities identified the dead women as 23-year-old Alexandria Pierce, 24-year-old Amesha Page-Smith and 22-year-old Adrianne Stevens. The gunman is 23-year-old Brinton Millsap.
Investigators say all the women were shot several times.
A motorist found the bodies on N.C. Highway 54. Investigators say the three women were shot to death inside the car, while the man was found dead outside the vehicle.
