Police say two suspects shot two officers at a Las Vegas pizza parlor before fatally shooting a person and turning the guns on themselves at a nearby Wal-Mart.

Las Vegas police spokesman Larry Hadfield says the spree began around 11:30 a.m. Sunday when a man and woman walked into CiCi's Pizza restaurant and shot two officers who were eating lunch.

One police officer was killed at the scene, while the other died during surgery, the Las Vegas Review-Journal reports. 

He says one of the suspects yelled, "This is a revolution," but the motive for the shooting remains under investigation.

Investigators say the two suspects then fled to the Wal-Mart across the street, where they shot a person inside and then killed themselves.

Police had the area surrounded. 

Both shooters were reportedly carrying large duffle bags and a bomb squad was called to the scene. It is unknown what, if anything, was in the bags.
