David M. Gonzalez, a 20-year-old Marine and small-arms repair technician with Marine Tactical Air Command Squadron 38, was found dead from a gunshot wound to the head in an armory at Marine Corps Air Station Miramar in San Diego on February 26, 2018. The discovery was made shortly before 1:30 p.m., and military and local law enforcement immediately launched an investigation into the circumstances.

Initial statements from military officials said the fatality was not believed to be a homicide but did not specify whether it was an accident or a possible suicide. No arrests or suspects were identified and investigators examined Gonzalez’s activities and interactions in the days and hours before the shooting while considering accidental discharge and other possibilities.

The case remained open with periodic reviews and no public litigation or murder charges reported. Did anyone who served with Gonzalez or who was at Miramar that day notice anything that could shed light on what happened?
