Video of a police shooting last week at a Burlington store that killed a 14-year-old girl and an alleged suspect in an assault. The officer who fired the shot that killed the girl was placed on administrative leave. The male suspect and the girl were the 16th and 17th people shot and killed by Los Angeles police officers in 2021 in a substantial increase in fatal police shootings over the past two years. Police fatally shot an 18th person – a man with a knife – late Sunday. The Los Angeles County medical examiner-coroner identified the girl Friday as Valentina Orellana-Peralta, 14, and ruled her death a homicide by a gunshot wound to the chest. The coroner identified the male suspect as Daniel Elena Lopez, 24. He died of a gunshot wound. The officer on administrative leave was not publicly identified. The shooting happened Thursday morning on the second floor of a Burlington clothing store in North Hollywood. Police responded to a report of someone being assaulted with a deadly weapon and of shots fired with people sheltering in place, Capt. Stacy Spell said. Officers shot at the suspect. The girl was in a changing room with her mother on the other side of a wall "directly behind the suspect," police said in a statement. Officers found her while searching for additional suspects and victims, police said. Investigators did not find a gun at the scene but found a "steel or metal cable lock, a very heavy lock" near the suspect that may have been used in the incident, Dominic Choi, assistant chief, said at a news conference last week. Choi said investigators were trying to determine whether the assault was random or targeted. He said investigators do not believe the teenager was related to the person who was attacked, who was taken to a hospital with injuries to her head, face and arms. Witnesses told KCBS-TV the suspect acted erratically inside the store crowded with holiday shoppers, threatened to throw items from the upper floor and attacked a woman with the bicycle lock. Mayor Eric Garcetti called the shooting an "unthinkable tragedy." "There is absolutely nothing more devastating than what Valentina Orellana-Peralta’s family is enduring, and there are no words that will take away their pain right now," Garcetti said in a statement. On Friday, Police Chief Michel Moore promised a "thorough, complete and transparent investigation" into the shooting. He said he directed the release of 911 calls, radio transmissions, bodycam video, any closed-circuit TV footage and other evidence by Monday.
