Martin Haro-Lozano, 45, was killed on June 27, 2020, at the Walmart distribution center in Red Bluff, California. He was waiting for his wife, who also worked at the facility, when a former employee, 31-year-old Louis Lane, drove an SUV into the lobby, set the vehicle on fire and began shooting with a semi-automatic rifle. Haro-Lozano was transported to a hospital by an on-duty deputy sheriff but died of his injuries. Four other employees suffered non-life-threatening injuries.

Authorities concluded Lane acted alone, exchanged gunfire with responding officers and died at the scene. Investigators reported no known relationship between Lane and Haro-Lozano, and they said the attack was not linked to any other investigations; a clear motive has not been identified. Walmart offered support to employees and cooperated with law enforcement.
