Authorities say they still haven’t determined a motive in Wednesday’s mass shooting in San Bernardino, Calif., but are looking into possible terrorism connections.
Police announced Thursday that they found 12 pipe bombs at a home connected to Syed Farook and Tashfeen Malik, the two suspects who opened fire at a social service center and left 14 people dead.
Police said that in addition to the two assault rifles and two handguns used in the massacre, they located a pipe bomb at the scene that actually appeared to be three individual devices combined into one and linked to a remote control. The two suspects died later in a gun battle with officers.
David Bowdich, the assistant director for the FBI’s Los Angeles field office, said the pipe bomb found at the scene spoke to “some level of sophistication certainly,” but said authorities are still working through evidence, including thumb drives and other electronic material, to determine a motive.
“It would be irresponsible and premature for me to call this terrorism,” David Bowdich told reporters, while saying nothing is being ruled out.
The FBI said the married suspects had traveled internationally and entered the United States in July 2014. Farook was a U.S. citizen, while his wife was in the country on a K-1 fiancee’s visa from Pakistan. Bowdich said the FBI is looking into whether they had been in contact with any international terrorism subjects.
Authorities also raised the number of injured victims from 17 to 21. No victims’ names have been released yet.
