The San Ysidro McDonald's massacre was a mass shooting which occurred at a McDonald's restaurant in the San Ysidro neighborhood of San Diego, California, on July 18, 1984. The perpetrator, 41-year-old James Huberty, fatally shot 22 people, including an unborn baby, and wounded 19 others before being killed by a police sniper approximately 77 minutes after he had first opened fire.
At the time, the massacre was the deadliest mass shooting by a lone gunman in U.S. history, being surpassed seven years later by the Luby's shooting. It remains the deadliest mass shooting in California history.
