One of the suspects in the San Bernardino shootings, Syed Farook, may have been motivated to carry out the attacks as a result of watching the Islamic State's propaganda videos, according to a Thursday night press conference by law enforcement.

Officials speculated Farook may have been radicalized by his wife Tashfeen Malik, who entered the U.S. from Saudi Arabia last year.

Investigators pointed to 1,600 rounds of ammunition found in the couple's rented SUV following a shootout between police and the suspects, as well as 3,000 more rounds of ammunition and 12 pipe bombs in their condo as indication that the pair had bigger plans.

Three remote control-operated pipe bombs were also left behind at the scene of the shooting, but were either not used or failed to detonate.
