DURHAM, N.C. — A man wanted by Durham police on armed robbery charges died Tuesday night after he apparently shot himself in the head.

Officers received an anonymous tip that 18-year-old Kenneth Anthony Cox was inside a duplex apartment at 1114-A South Street. As officers surrounded the duplex, they heard a gunshot from inside the house.

Officers went inside and found Cox lying in a back room. He was taken to Duke University Medical Center, where he later died.

Cox was wanted on three counts of robbery with a dangerous weapon in connection with a robbery and double shooting Saturday night on Sedgefield Street. Cox was not charged with either shooting.

Durham police were dispatched to a disturbance with a weapon call at a house in the 1000 block of Sedgefield Street at 7:23 p.m. Saturday. When they arrived, they found two teenagers who had suffered gunshot wounds.

One teen, 19-year-old Marcus Jones of Durham, suffered a gunshot wound to the back. He was taken to Duke University Medical Center for treatment.

A second teen, 17-year-old Jaquienton Sellars of Hillsborough, suffered a gunshot wound to his right thigh.

Investigators believe the shootings occurred during a robbery.

One man, Jerry Lamont Cox, 19, of 1012-A Sedgefield Street, was arrested Saturday night. He was charged with three counts of armed robbery and one count of assault with a deadly weapon with intent to kill, and his bond was set at $150,000.
