San Diego mosque shooters identified

The FBI and local police are investigating the backgrounds of the two teenage gunmen who killed three people at a San Diego mosque on Monday.

Cain Clark and Caleb Vazquez, who took their own lives after the attack, reportedly met online and shared nihilistic, white supremacist ideologies.

A 75-page manifesto discovered in their vehicle praised other religious-inspired mass shootings and expressed hatred toward various groups.

The three victims are being remembered as heroes for distracting the gunmen and protecting roughly 140 children inside the building.
