Both California shooters 'radicalized for quite some time'

The husband and wife who killed 14 people in last week's shooting rampage in California were both radicalized and "for quite some time," the FBI official in charge of the investigation said Monday.

David Bowdich, the FBI's assistant director in charge of the Los Angeles field office, said investigators were still trying to determine how and by whom Syed Farook and his wife Tashfeen Malik were radicalized before the December 2 shooting.

"But I will say this -- as the investigation has progressed, we have learned and believe that both subjects were radicalized and have been for quite some time," he said.
