On December 2, 2015, Syed Rizwan Farook and Tashfeen Malik, walked into a banquet room at the Inland Regional Center in San Bernardino, California, armed with semi-automatic weapons. At the time, the San Bernardino County Department of Public Health was holding a training event and holiday party. Approximately 75-80 people were in attendance. The couple opened fire, and in a matter of several minutes, killed 14 people and seriously injuring 22 others. The couple left the scene before the police arrived at the crime scene.
Immediately thereafter, law enforcement officials started a search for the couple who left in a black SUV. Based on a tip from one of Farook’s neighbors, officers went to his home and a car chase ensued. The SUV eventually stopped and there was an exchange of gunfire between the couple and officers. The couple was killed in the five-minute exchange.
While investigating the case, investigators found a possible link to a foreign terrorist group thereby ruling it a terrorist attack. However, after FBI investigations, it was concluded the couple were “homegrown violent extremists” inspired by foreign terrorist groups. The investigation stated they were not directed by a particular foreign terrorist group or part of any terrorist cell.
