Two gunmen stormed a social services center in San Bernardino, Calif. on Wednesday and opened fire. In a televised press conference around 5 p.m. Eastern, Chief Jarrod Burguan of the San Bernardino Police Department said that at least 14 people were killed in the mass shooting that shook the Southern California community. Another 21 people were injured during the attack, Burguan confirmed Thursday. According to Burguan, the suspected gunmen's motives were not immediately clear.
