Officers confirmed the suspects as Syed Rizwan Farook, 28, and Tashfeen Malik, 27.
The couple had more than 6,000 rounds of ammunition and a dozen pipe bombs on them and elsewhere, authorities said as they sought to determine whether the pair had links to Islamic militant groups.
They were a married couple who dropped off their 6-month-old baby with her grandmother hours before carrying out the deadly rampage, according to a family member.
In a press conference US President Barack Obama said it is possible the mass shooting was “terror-related” but the motive is not yet clear.
Law enforcement sources have said Farook was radicalised and was in contact with an individual under FBI investigation for terrorism links but other motives may have played a role in the shooting.
Farook attended a Christmas party with colleagues at the San Bernardino County Health Public Health Department but had left in an “angry” state, according to witnesses.
He was next seen by his co-workers dressed in battle gear and wielding an assault rifle.
The suspects have killed at least 14 people and injured another 17 - two of which [sic] remain in a critical condition, California Hospital confirmed. » | Dion Dassanayake, Peter Henn, Jake Burman & Selina Sykes | Thursday, December 3, 2015
