The Yosemite killer has been convicted of murdering three tourists visiting the national park.
Cary Stayner, a former motel handyman, faces the death penalty in California for killing a woman, her daughter and a teenage friend from Argentina in 1999.
The San Jose jury found Stayner guilty on three counts of first-degree murder in the deaths of three park tourists. The jury must now decide if 41-year-old Stayner was sane or not at the time of the killings. That phase of the trial is set to begin Thursday.
Defense lawyers conceded that Stayner killed them, but said he was crazy at the time. They asked for a second-degree murder conviction, which would have spared him the death penalty.
The crime was unsolved until Stayner struck again nearly six months later, snatching a Yosemite nature guide and beheading her in the park. He´s serving a life sentence without chance of parole after pleading guilty in federal court to first-degree murder.
