It was one of the most infamous crimes in California history:
Three women disappeared while visiting Yosemite National Park and savagely killed by the handyman at their motel.
Caught months later after beheading a nature guide, Cary Stayner gave the FBI a detailed confession to all four slayings.
Three years later, Stayner is finally going on trial for killing the tourists.
Opening statements are expected Monday.
Stayner already is serving life without parole in federal prison after pleading guilty to killing the guide, Joie Armstrong. But state prosecutors want the death penalty. Stayner has pleaded innocent by reason of insanity.
Executing him will require a trial that is expected to cost $3 million dollars.
