– LAPD Sgt. Frank Preciado tells NBC Los Angeles it was "one of the most horrific crime scenes I've seen in a while." Three people were killed and a dozen wounded in a gun battle that broke out shortly after midnight Saturday inside a Los Angeles restaurant. Police believe it started with an argument during a birthday party at a "makeshift restaurant without permits." The Los Angeles Times describes the business—named Dilly's—as a Jamaican restaurant with a DJ and dominoes games operating out of house. Police say three people left Dilly's during the party and came back with guns. They started shooting at another group at the party, and others shot back. Diners were caught in the crossfire. “When we got there, there were three people dead and people running everywhere,” Preciado says, describing a "bloody scene with shell casings everywhere." Approximately 50 people were in the restaurant when the shooting started. "It was just 'pop, pop, pop, pop, pop," a neighbor says. "It didn't stop. It just kept going." Two people of interest have been detained, and police are looking for suspects and witnesses. Some of the wounded are in critical condition. A neighbor tells CBS Los Angeles he was shocked when he heard about the shooting. "Around this area...we don’t really have any problems with anybody," he says. "Everyone knows everyone and we’re all pretty much like family."
