David Flores Delgado was 11 years old when he was killed on July 18, 1984, at the San Ysidro McDonald’s. He was among the 21 people killed when 41-year-old James Huberty opened fire inside the restaurant during a 77-minute attack that left 19 others wounded before Huberty was fatally shot by a police sniper. David had reportedly been visiting the McDonald’s with friends to take advantage of a promotional ice cream cone offer.

Investigators later examined Huberty’s background and found a history of mental health problems; he had tried to get help days before the shooting but did not receive immediate intervention after a miscommunication at the clinic. No other suspects were identified because the shooter died at the scene. Families pursued litigation after the massacre, and memorials have been held to honor the victims, including David.
