LAS VEGAS - 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.
Gov. Brian Sandoval issued a statement saying he was devastated by the murders of the two officers and an "innocent bystander."
The shooting 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 fatally shot a person inside and then killed themselves in an apparent suicide pact, Hadfield said.
"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."
Clark County Assistant Sheriff Kevin McMahill said at a news conference that the male suspect yelled "everyone get out" before shooting at Walmart. The man and woman then went to the back of the store.
The names of the suspects and victims and their cause of death will be released by the Clark County coroner's office.
Walmart employees and shoppers were taken to a nearby clothing store to be interviewed by police. The restaurant and Walmart remained closed as detectives processed evidence.
Walmart issued a statement saying it's working with police on the investigation.
"We express our deepest condolences to everyone who has been affected by this senseless act of violence," company spokesman Brooke Buchanan said.
