A criminal investigation into the death of a McCloud man is closed now that an autopsy has shown that he died of natural causes. 46-year-old Steven Ray Guyman died Sunday at a Redding Hospital. Guyman was found unconscious last week at his home in McCloud. The Siskiyou County Sheriff's Office called the circumstances "suspicious", only describing his injuries as "debilitating". He apparently had visible hemorrhaging beneath the surface of his skin on and around his face that resembled bruising as if he had been beaten. A forensic autopsy has now revealed that Guyman suffered a spontaneous intracerebral hemorrhage caused by a ruptured blood vessel in his brain. The bleeding apparently had gone undetected for some time until it led to his collapse and ultimately his death. The sheriff's office is no longer seeking tips from the public.
