Michael Johnson, 27, was shot to death in Long Beach, California, on September 13, 2016. Responders found him in the early morning at Locust Avenue and East 12th Street with a gunshot wound to his upper torso; the Long Beach Fire Department pronounced him dead at the scene.

Authorities have not released suspect information or a motive. Investigators have linked the killing to a larger pattern of violence tied to MS-13, specifically members of the Sailors clique, who carried out a series of brutal attacks in the area around that time. The campaign has been described as part of efforts by the gang’s leadership, including Alexi Saenz, to assert control, and law enforcement efforts such as Joint Task Force Vulcan have focused on disrupting the group.

If anyone knew Michael Johnson or has information about the shooting on September 13, 2016, please come forward to the Long Beach police.
