Victor Maximiliano Rivera, known as Chito, was 25 when he was killed on July 18, 1984, in San Ysidro, California. He was one of 21 people shot dead inside the McDonald’s restaurant during a rampage carried out by a single gunman who entered the restaurant and opened fire indiscriminately.

The shooter, James Huberty, was fatally shot by a SWAT team sniper after the attack, which the account says lasted 77 minutes. The aftermath included lawsuits by victims’ families against McDonald’s and Huberty’s estate, and the incident prompted changes in police response protocols and renewed debate about gun control and mental health issues.

If anyone knew Victor Rivera, his life in San Ysidro, or was at the McDonald’s that day and can add details, please share what is known.
