A man in his 20s was shot and wounded, and paramedics took him to a hospital in stable condition, Jacobs said.
The shooting in an unincorporated county area apparently involved an off-duty sheriff's deputy, Jacobs said. It was unclear which law enforcement agency the deputy was affiliated with.
The eastbound freeway was closed at Crenshaw Boulevard about 8:35 a.m., according to the California Highway Patrol.
