On December 2, 2015, 14 people were killed and 22 were seriously injured in a terrorist attack in San Bernardino, California, which consisted of a mass shooting and an attempted bombing. The perpetrators, Syed Rizwan Farook and Tashfeen Malik, a married couple living in the city of Redlands, targeted a San Bernardino County Department of Public Health training event and holiday party, of about 80 employees, in a rented banquet room. Farook was an American-born U.S. citizen of Pakistani descent, who worked as a health department employee. Malik was a Pakistani-born lawful permanent resident of the United States.
After the shooting, the couple fled in a rented sport utility vehicle (SUV). Four hours later, police pursued their vehicle and killed them in a shootout. On December 3, the Federal Bureau of Investigation (FBI) opened a counter-terrorism investigation. On December 6, in a prime-time address delivered from the Oval Office, President Barack Obama defined the shooting an act of terrorism.
