On Friday, December 29, 2017, at approx. 2:25 p.m., officers responded to a shooting that was reported to have occurred at a business in the 300 block of E. San Antonio Drive, which resulted in the death of two male adults, and the injuring of a third.

Officers arrived at the scene, and based on the circumstances, immediately formed an Emergency Action Team (EAT) to enter the building and search for the suspect. Once inside, officers located a deceased male subject with a gunshot wound to the upper body. A second deceased male subject, who had been struck by gunfire, was also located.

Officers also learned that a third male subject had been struck by gunfire, and had been transported to a local hospital by a third party prior to police arriving.

The preliminary investigation determined that this was a workplace violence incident that occurred at a law firm, and all parties involved worked at this office. It was further determined that 58-year-old John Alexander Mendoza of Redondo Beach, shot the two male victims, before shooting himself. A gun was recovered at the scene.

One victim, identified as 75-year-old Major Langer of Rolling Hills, who had been struck in the torso by gunfire, was determined deceased at the scene by Long Beach Fire Department paramedics. The second victim, a 64-year-old male, was struck in the torso and lower body and remains hospitalized in stable condition, and is expected to survive.

Several employees were in the office at the time of the shooting, however, no other injuries were reported. A motive for the shooting remains under investigation.
