Until the Medical Examiner issues a cause of death we really don't know if a homicide took place.  If we agree that the suspect has mental issues, then it follows that we also should take any so-called "confession" with a huge grain of salt.  From what's been reported so far, I can see him charged with something akin to mishandling or abuse of a corpse but not much else.  Until we learn more, even the $2 million bail as reported by the police seems excessive.
