CHARLESTON, S.C. (AP) — A man has been convicted of murder in the shooting death of a South Carolina woman on Mother's Day, 2015.

A Charleston County jury convicted Kenneth Lamont Robison, 18, of North Charleston on Thursday, local media reported.

Dena Brown, 36, was shot on her way home from a Mother's Day celebration when her vehicle came under fire because it looked like one that had been involved in an earlier shootout, prosecutors said.

Robinson was also convicted of four counts of assault and battery. He has not been sentenced yet.

Prosecutors and the defense agreed Brown was not the trigger man. But he was charged because he was involved in the circumstances that led to the killing.

Richard Dara Simmons, 23, of North Charleston pleaded guilty in January to murder and four counts of attempted murder.

Police were notified that two cars were racing through a North Charleston neighborhood with gunfire being exchanged between the vehicles. The gunfire continued onto Interstate 26, but a Chrysler broke away, authorities said.

A short while later, the people in the other car spotted a Chrysler and fired into it, police said.

Brown was struck in the neck and ran into a wall near a gas station. The mother of three later died at a hospital.

Outside the courthouse, Brown's mother said the murder conviction was unexpected relief. Marilyn Wilson said she didn't think the jury would find Robinson guilty of such a serious crime because of his age.
