Two suspects shot and killed two police officers at a Las Vegas pizza restaurant Sunday before fatally shooting a third person and killing themselves inside a nearby Walmart, investigators said.
The spree began around 11:30 a.m. Sunday when a man and woman walked into CiCi's Pizza and shot two officers who were eating lunch, Las Vegas police spokesman Larry Hadfield said.
One of the suspects yelled, "This is a revolution," but the motive for the shooting remains under investigation, Hadfield said.
The two suspects then fled to the Walmart across the street, where they shot a person inside and then killed themselves in an apparent suicide pact, Hadfield said.
The two officers killed while they ate lunch have been identified as Alyn Beck, 41, and Igor Soldo, 31.
"It is truly a tragic day here in the Las Vegas Valley," Sheriff Doug Gillespie said at a news conference. "We have lost two officers with young families."
Beck leaves behind a wife and six children; Soldo leaves behind a wife and baby. The shooting victim at the Walmart, a woman, has not yet been identified.
"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 restaurant and Walmart remained closed as detectives processed evidence.
