FBI Trying to Solve Riddle of Suspects' Travels After San Bernardino Attack

Authorities investigating the attack that killed 14 people last month in San Bernardino asked for the public's help Tuesday in filling out the timeline of the assailants' moves that day.

David Bowdich, the assistant director in charge of the FBI's Los Angeles office, said investigators have found no evidence that there were any targets other than the Inland Regional Center, where Syed Rizwan Farook, 28, and his wife, Tashfeen Malik, 29, opened fire Dec. 2 on a holiday luncheon gathering of Farook's co-workers in the county health agency.

Investigators specifically need information about an 18-minute gap in the timeline between the deadly attack at the center and the pursuit and shootout in which both attackers were killed.

Bowdich said investigators hope to find out if the assailants contacted anyone or stopped anywhere between 12:59 p.m. and 1:17 p.m. that day. The rest of their movements through the adjacent cities of San Bernardino and Redlands have been tracked.

According to the Los Angeles Times, investigators are still trying to understand the suspects' travels after the attack:

Bowdich said that investigators had been able to show that the couple drove back and forth within a large L-shape area after the shooting, stopping at a parking lot near the Inland Regional Center, where the shooting occurred, and at a nearby lake.

Bowdich said agents hadn't been able to determine why the couple drove around after the attack, but hope that filling in the 18 minutes could help.

“A lot of zig-zagging around, going back and forth on the highway," he said of Farook and Malik. "There is no rhyme or reason to it that we can find yet."

Bowdich urged anyone with information that could be relevant to the investigation, including video, to come forward.
