(Las Vegas, NV)  --  Las Vegas police believe yesterday's deadly shooting rampage at a restaurant and a Walmart store was an isolated act.  Cops identified the couple that shot and killed two police officers and a bystander as Jared and Amanda Miller.  Police don't think the Millers specifically targeted officers Alyn Beck and Igor Soldo prior to yesterday's shootings.  Bystander Joseph Wilcox tried to stop the suspects and was shot to death by the couple.  Las Vegas police cornered the Millers in the back of a Walmart store where they took their own lives.  The couple left behind a note saying "the revolution is beginning."
