(FOX NEWS) -- Three people have been killed, including two Las Vegas police officers, in shootings at a Las Vegas restaurant and Walmart. Las Vegas police spokesman Larry Hadfield told The Associated Press that the spree began around 11:30 a.m. Sunday when a man and woman walked into CiCi's Pizza restaurant on North Nellis Boulevard and shot two officers who were eating lunch. The suspects took the officers' weapons and ammunition before storming out of the pizzeria, Assistant Sheriff Kevin McMahill told KVVU Fox 5. The two suspects then fled to the Walmart across the street, where they shot and killed a person inside and then killed themselves in an apparent suicide pact, Hadfield said. Police and a SWAT team were dispatched to the scene, KVVU Fox 5 reports. Hadfield said one of the suspects yelled, "This is a revolution," but the motive for the shooting remains under investigation. "I think in any case where people are ambushed and shot it's upsetting to the public," Hadfield told The Associated Press. "We don't know anything about the suspects yet and are trying to learn more." The names of the suspects and victims and their cause of death will be released by the Clark County coroner's office. The restaurant and Walmart remained closed as detectives processed evidence.
