A year after the San Bernardino terror attack, the FBI is still struggling to answer key questions

In  the year since Syed Rizwan Farook and Tashfeen Malik killed 14 people in a terrorist attack in San Bernardino, authorities have conducted more than 600 interviews, gathered more than 500 pieces of evidence and served dozens of search warrants.

They launched an unprecedented legal battle with Apple in an effort to unlock Farook’s iPhone and deployed divers to scour a nearby lake in search of electronic equipment the couple might have dumped there.

But despite piecing together a detailed picture of the couple’s actions up to and including the massacre, federal officials acknowledge they still don’t have answers to some of the critical questions posed in the days after the Dec. 2, 2015, attack at the Inland Regional Center.
