More details unfolding as community tries to cope day after San Bernardino mass shooting

SAN BERNARDINO, Calif. (KFSN) -- Hundreds of people are gathered for a vigil to honor the victims and their families. They're trying to move on, but it may be a while before they can solve the mysteries still surrounding this situation.

FBI agents removed bags of evidence Thursday from a car and a home connected to Syed Farook and his wife Tashfeen Malik. Investigators revealed they found thousands of rounds of ammunition and 12 pipe bombs-- some of the leftovers after the suspects fired at least 130 shots at two scenes and left three bombs at the Inland Regional Center. Agents also collected a lot of digital evidence, like computers and phones, much of which they're sending back to Washington D.C. for faster analysis.

But answers will not come fast. "This is not your average investigation. We have multiple scenes. We have many victims and it will take time," explained David Bowdich, FBI Assistant Director.

The FBI won't confirm this was a terrorist act, still looking into the possibility Farook intended to target co-workers at the County Health Department. They acknowledge the attack required a lot of planning and one source tells the Associated Press Farook did contact extremists already under FBI scrutiny.

At the nearest shooting range to Farook's home, employees tell me the suspect never practiced there. But because of the shooting, they've stopped renting out shotguns.

The massacre has left a permanent scar on the victims and their families, and in the neighborhoods still treated as active crime scenes a day after the shooting. The suspects' neighbors tell me it's been a nerve-wracking day and a half. "It's very chilling to know people are like that, and it could be the people next door to you," said Ashley Woods, Farook's neighbor.

A lot of those nerves could be soothed at the vigil Thursday tonight as the crowd shares in their grief and gathers new strength in being together.
