Prosecutors say he pulled the trigger.
Another man, Leroy Barnes Jr., pleaded guilty to conspiracy to commit an assault with a deadly weapon with intent to kill and conspiracy to commit an assault with a deadly weapon inflicting serious injury.
Clarence Grubbs and his girlfriend were shot as they sat under a gazebo at Wolf Village Apartments on Gorman Street on July 29. Prosecutors say it was a hit ordered by a leader of the Crips gang because Grubbs witnessed a robbery. Grubbs was shot five times but lived. His girlfriend, Caroline Pittman, was shot in the foot.
Alex Dorsey, the alleged Crips leader who ordered the hit, has already pleaded guilty to attempted first-degree murder and two counts of solicitation to commit murder.
A third man allegedly involved in the attack has yet to plead.
