SALEM, Ore. - In 2011, Josh Shaddon was found guilty except for insanity in the 2009 slaying of his mom, Gerlene Thorne.
The crime is one he reportedly doesn't remember.
"Before the methamphetamine, he was as good of a person anyone could ask for," said Hal Simpson, Shaddon's father.
Shaddon was admitted to the state hospital after his conviction in 2011.
Now he is requesting to be released, something his own father says may not be a good idea.
"If he gets on the street and back into the drugs, he's in trouble again," Simpson said. "It's just instant."
Before the murder, Simpson recalls his son was distraught, even paranoid.
"It was obvious," he said. "He was telling us about tracking devices being placed on vehicles."
Psychologist Dr. Stephen Scherr diagnosed Shaddon with paranoid schizophrenia after the killing.
But Shaddon's attorney now argues there have been no reported symptoms of psychosis while his client has been at the hospital.
Also, hospital officials said there has been no diagnosis of schizophrenia.
That his son could go free concerned Simpson.
"I don't think he should be released and just go wherever he wants, you know what I mean?" he said.
The father supported the court's decision Wednesday to keep Shaddon in custody. He can request another hearing in 6 months.
