FBI divers searched a lake near the site of the San Bernardino, California, shooting on Thursday, looking for evidence in the case, authorities said.

“The reason we’re here searching this lake today is because we did have a lead that the suspects came to this area,” FBI Assistant Director David Bowdich said at a press conference on Thursday.

He added: “They’re seeking evidence – the specific evidence we are looking at, we’re not going to discuss.”

Married couple Syed Rizwan Farook, 28, and Tashfeen Malik, 29, killed 14 people and wounded 22 others after opening fire on at a Dec. 2 holiday party on at Inland Regional Center.

Bowdich said that the search of the lake could last for days. “We would be remiss not to make this search,” he said, adding that he doesn’t know whether the suspects threw something into the lake. “I will not get into what led us here. There were a couple of things that led us to this park.”

Bowdich went on to apologize for the overwhelming presence of authorities. “The San Bernardino area has been invaded by FBI, ATF [and San Bernardino authorities],” he said. “I know it is disruptive to the area.”

Bowditch also said that reports that Farook planned a 2012 attack on the U.S. were exaggerated, stating that the FBI is investigating these claims, but emphasizing that there was “never a credible threat to the U.S.”

Farook and Malik died in a shootout with police after authorities traced them to a home in Redlands, California. There, officials found the parts to build 19 pipe bombs, along with thousands of rounds of ammunition.

Investigators have interviewed more than 400 people in connection with the case.
