The attackers behind the deadly shooting in San Bernardino, California, last week had both been radicalized “for some time,” the FBI said Monday.
David Bowdich, the assistant director in charge of the FBI’s Los Angeles office, confirmed speculation to the effect of the killers’ radicalization, but said that investigators have not yet determined whether the attackers, Syed Rizwan Farook and Tashfeen Malik, were self-radicalized or subject to influence from others, Politico reported.
Bowdich also said that it remains unclear whether Farook, a U.S. citizen who had traveled to the Middle East multiple times, was influenced by Malik, his wife who was a Pakistani national. Bowdich also noted that radicalization often happens “on the Internet.”
