As many as three assailants attacked a gathering inside a San Bernardino, Ca., office building Wednesday, killing at least 14 people and wounding 17 others, the Los Angeles Times reports. The shooters, who carried long guns and wore masks and camouflage clothing, opened fire on a holiday party being held by county employees. The shooting took place in a large conference room at Inland Regional Center, which serves people with developmental disabilities. An altercation among people attending the gathering may have led to the assault. A federal law enforcement source said that one shooter may have left the party after getting into an argument and returned with one or two armed companions.
A black sport-utility vehicle was seen fleeing from the office complex where the shooting occurred. Authorities confirmed that a suspect had been shot in connection with the car chase, but it remained unclear whether the pursuit was linked to the attack. The San Bernardino County Public Health Department rented the conference room where the shooting took place, and they were hosting a banquet. The room, which holds as many as 200 people, was decorated for a holiday party.
