SAN BERNARDINO (CBSLA.com/AP) — A law enforcement official says an FBI dive team is searching a small San Bernardino lake as part of an investigation into the massacre that killed 14 people.

The dive team searched Seccombe Lake Park on Thursday. The small lake is in an urban park about three miles north of the Inland Regional Center, the site of the Dec. 2 shooting.

KNX 1070’s Jon Baird reports the search is believed to have begun around 7:30 a.m., though it’s unclear what the team is looking for.

FBI officials said they had a lead that San Bernardino shooters Syed Farook and Tashfeen Malik are believed to have come to the lake following the shooting on Dec. 3.

Divers were searching for a computer hard drive that may be in the water, investigators told CBS News.

Authorities say Syed Farook and his wife, Tashfeen Malik, ambushed his fellow San Bernardino County health inspectors at a holiday party. The couple died hours later in a police shootout.

Since the shooting, the FBI has interviewed hundreds of people and conducted searches in the area looking for evidence.

CBS2’s Crystal Cruz reported from the lake Thursday evening after officials roped the area off.

She said they would be back again Thursday looking for more clues.

CBS News, meanwhile says a friend of Farook’s — Enrique Marquez — is likely to be charged with material support with terrorism. Marquez legally purchased the two rifles used in the massacre.

On Thursday, a friend of Marquez’s also said she was surprised he owned weapons.

“I didn’t know he owned rifles,” said Viviana Ramirez ,”It was shocking. I didn’t think he would be part of any of that.”

Ramirez said she met Marquez on a Riverside Collge confessions chat page where people post anonymously and others comment.
