The shooting was reported at the ASL Liquor and Market in the 8500 block of Paramount Boulevard about 10:15 p.m., a spokesperson for the Downey Police Department told KTLA. Police responded to the scene and found a man down behind the cashier’s counter inside the store. The victim, identified by L.A. County coroner’s officials as 44-year-old Gurpreet Singh, of Cerritos, was pronounced dead at the scene. Customers told KTLA that Singh, who went by the nickname GP, worked at the store and may have even had an ownership stake. “I can’t believe it happened to him … He’s such a good guy,” Angela Bennett said. Bennett, who lives in the area, said the incident is out-of-character for the neighborhood. “Nothing like this ever happens over here,” she told KTLA. “I’ve been here 14 years … never happened.” Surveillance video from outside the store showed a man running up to the door and entering about the time of the shooting. The man left the store a short time later. Police have not confirmed if the man in the video is a suspect in the shooting and have not given a description of the gunman. It was unclear whether some type of robbery or attempted robbery may have led to the shooting, but investigators are looking into that possibility. Investigators also noticed that a window on one side of the store had been broken. Anyone with information was asked to call the Police Department at 562-904-2330.
