Two Las Vegas police officers and a civilian are dead after two shooters ambushed the cops at a pizza restaurant on Sunday afternoon and then got into a gunfight at a busy Walmart.

The two shooters, a man and woman, stormed into CiCi’s Pizza at around 11:20 a.m. and confronted two uniformed officers with Las Vegas Metropolitan Police Department eating pizza on a break and gunned them down.

Sheriff Douglas Gillespie asked for patience during the investigation because both of the officers were “family men” and “they’re leaving behind loved ones.”

The Las Vegas Review-Journal reports one of the shooters shouted, “This is the start of a revolution,” before killing one of the officers execution style.

The officers were identified as Officers Alyn Beck, 42, and Igor Soldo, 32.
