Oklahoma ? A murder suspect surrendered to police following a three-hour standoff at an apartment complex that was complicated by a crowd of bystanders who threw rocks at police, authorities said.

After dispersing the crowd, officers negotiated with murder suspect Rico Starks, 18, for several hours before he surrendered about 12:30 a.m. EDT on Sunday, said Officer Scott Walton.

Walton said police were not sure whether Starks had been armed because he had been moving from location to location in the evacuated building.

Walton said officers were first called to the scene about 9 p.m. and encountered neighborhood opposition.

Four officers suffered minor injuries – none requiring hospitalization – from thrown rocks and bottles. Tulsa Police Capt. Steve Bayles said that no members of the public were injured.

Starks is charged with second-degree murder in the killing of 18-year-old Mark Jordan, who was shot Aug. 21 in north Tulsa.
