Police said 14 people were killed when a man and woman opened fire at the Inland Regional Center in San Bernardino on Wednesday. Two suspects who were killed in a dramatic shootout with officers have been identified.
Officials said the suspects were believed to be married or engaged.
Officials said Farook and Malik were dressed in assault style clothing and had assault rifles.
The ATF said two rifles and two handguns were recovered in their investigation and officials are working to trace the serial numbers on the weapons.
Officers swarmed a neighborhood about a mile from the SUV shootout, apparently in a hunt for a possible third gunman.
A person seen running from the scene was detained, police confirmed. Officials would not call the person the third suspect, but just a person of interest.
Police said later Wednesday evening that they now have reason to believe that the couple were the only shooters involved.
