"The suspects in the San Bernardino holiday party shooting were armed with four guns, an explosive device and several magazines of ammunition in a “well-planned” attack, police and federal officials said. Syed Rizwan Farook, 28, a U.S.-born health inspector for San Bernardino County, and Tashfeen Malik, 27, were carrying two .223-caliber assault rifles and two semi-automatic handguns... San Bernardino Police Chief Jarrod Burguan said the two .223-caliber assault rifles were a DPMS model and a Smith & Wesson M&P 15 model, while the two semi-automatic hand guns were manufactured by Llama and Smith & Wesson."
