The three men killed in the mass shooting at the Islamic Center of San Diego were mourned at a memorial service on May 21 in San Diego before being buried besides each other. Hundreds of members of the Muslim community mourned the security guard and father of eight Amin Abdullah, who police say prevented more deaths, along with two members of the mosque, Nader Awad and Mansoor Kazziha, who were gunned down by teenage killers Cain Clark, 17, and Caleb Vazquez, 18. The prayer service was held at the Snapdragon Stadium located at the San Diego State University Mission Valley Campus.
