The firearms the shooters, aged 17 and 18, used in the fatal rampage were registered to one of their parents

The two teenage assailants responsible for a mass shooting at the Islamic Center of San Diego, California, rushed toward the mosque “fully armored” with handguns and rifles, authorities said.

A security guard shot and struck one of the shooters, according to members of the mosque – but the attacker continued charging. The guard – Amin Abdullah – also alerted administrators of the school at the Islamic Center, telling them to go into lockdown, before he was shot and killed. “If it was not for him … The carnage would be much worse,” said imam Taha Hassane. “He sacrificed his life.”
