A Shasta Lake City man accused of stabbing his father to death last year now claims he was insane at the time. On the night of January 22nd of last year deputies were called to the Cabello Street home of Salvadore Giordano. The 83-year-old man had been discovered dead by his wife Carole. Salvadore’s son, Stephen Matthew Giordano, had been staying with the couple and had apparently been fighting with them frequently, sometimes violently. When Carole left earlier in the evening, she said Salvadore and Stephen were praying about the fighting. When she returned Stephen was gone and her husband was dead. She didn’t know if he had been stabbed or beaten but reported a lot of trauma to his face and neck and blood pooled around his head. Stephen was found later hiding in the bathroom of a home on Shasta Street. He had blood on his hands, clothes, and boots. During questioning he allegedly admitted to being responsible for the death of his father. A jury trial was set to begin this week but on Friday Stephen changed his plea to not guilty by reason of insanity. The new trial date is June 20th.
