San Diego mosque attack prompts tribute to security guard who saved lives

A security guard at the Islamic Center of San Diego was killed while heroically engaging two teenage gunmen, triggering a lockdown that reportedly delayed and deterred the attackers and likely saved lives. The suspects died by self-inflicted gunshot in a nearby car, and two other victims were killed, bringing the toll to three. Authorities are investigating the incident as a hate crime with FBI involvement, while a fundraiser for the families has raised nearly $3 million and police have signaled increased security at houses of worship.
