The married couple who shot dead 14 people at a social services centre in California gave no "warning signs", a lawyer for the pair's family said.

"There's so little there to understand or explain what happened or why it happened," David Chesley told CNN.

The suspects - Syed Rizwan Farook, 28, and Tashfeen Malik, 27 - were killed in a shootout with police.

No motive has been established for Wednesday's killings at the Inland Regional Center in San Bernardino.

An FBI investigation is exploring several possibilities, including terrorism, a workplace grudge or a combination of factors.

Farook had been in contact with known Islamic radicals on social media, unnamed US intelligence officials said.

Mr Chesley said the couple's family "never saw any warning signs or any real characteristics that would let them know that any of this was going to take place".

"This was a person who was successful, who had a good job, a good income, a wife and a family. What was he missing in his life?" Nizaam Ali, who attended a local mosque with Farook, told AP.

Farook's brother-in-law Farhan Khan said he was "very upset and angry" with Farook, and had started proceedings to adopt the couple's six-month-old daughter.

"God gave you a gift of a daughter," he told NBC. "And you left that kid behind... What did you achieve?"

Bomb equipment, weapons and thousands of rounds of ammunition were found in the suspects' home, with local police saying it appeared the duo planned on carrying out another assault.

Up to 80 people were inside the social services centre in the city of San Bernardino when the shooting began.

"The number of people who were injured and unfortunately already dead, and the pure panic on the faces of those individuals that were still in need and needing to be safe," Lt Mike Madden said.

A vigil was held on Thursday for the victims at the San Manuel stadium in downtown San Bernardino, with family and friends of the victims attending.

President Barack Obama said it was possible the attack was terrorism-related but stressed the authorities did not know yet why it had occurred.

San Bernardino is the deadliest mass shooting in the US since 26 people were killed at a school in Newtown, Connecticut in 2012.
