The defense for Yosemite killer Cary Stayner is trying to bolster the testimony of a court-appointed psychiatrist who spent the last three days describing a slew of mental illnesses haunting Stayner.
Defense attorney Michael Burt Thursday asked Doctor Jose Arturo Silva to explain again in great detail how he concluded that Stayner suffers from obsessive thoughts about Bigfoot and might have a mild form of autism.
A day earlier, the prosecutor cross-examining Silva pointed out that other doctors had different opinions about Stayner´s mental illnesses. Stayner has pleaded innocent by reason of insanity in the 1999 killings of Yosemite tourists Carole and Juli Sund and Silvina Pelosso. He faces the death penalty. He already is serving life in prison for beheading a park guide.
