SAN BERNARDINO, Calif. (AP) -- The FBI says the California shooters have participated in target practice, including once within days of the attack that killed 14 people.
David Bowdich, assistant director of the FBI's Los Angeles office, said at a news conference Monday that Syed Farook and his wife, Tashfeen Malik, participated in target practice at ranges within the Los Angeles area.
He says both were radicalized and had been "for some time." He says the bureau doesn't know when or whether anyone else radicalized them.
The FBI has said it's investigating the shooting at a holiday gathering of Farook's co-workers as an act of terrorism.
Bowdich says they found 19 pipes in the couple's home in Redlands, California, that could be turned into bombs with all the right components.
