OKLAHOMA CITY - New concerns surface after a man who killed and dismembered his mother may face possible freedom.
Gerald Hume, 54, was found not guilty of murder earlier this year by reason of insanity.
If a psychiatrist and a judge agree next week that Hume is well, he could get out of jail.
With that possibility, Hume's cousin, Scott Kuper, breaks his silence.
"I had a lot of anger, a lot of anger," said Kuper. "I just feel like I need to tell the story that was never told."
In November 2012, Kuper could only watch as police stood outside his aunt's, Janet Kay Hume, home during a standoff with her son.
"The officer said, 'Do you think she's in that house?' and I said, 'I know she's in that house, and I think she's probably dead.'" said Kuper.
Days earlier he called police so they could check on his aunt. He usually talked to her on the phone once a week, but she wasn't answering.
He knew she lived with her son, Hume, who had a history of mental illness.
Once police went into the home after a two-day standoff, they realized Kuper was right.
"She'd been shot 11 times," said Kuper. "...she was cut into eight pieces. Part of her was in the freezer."
He knew that for the past 20 years his cousin had suffered from schizophrenia
"He was married. He was going to school at OU. He was going to be an engineer," said Kuper.
That's when he says the mental illness began, and Hume's life became a series of outbursts on and off medication up to the moment Hume murdered his mother.
In jail, Kuper says Hume wrote him a two page letter.
In it, he says "I'm sorry about mom's death because a lot of people like me did not want her to die..."
Hume goes on to say that he is not responsible because, "...other people who make my body and brain do things that are against what I want by using their bodies, brains and technology machines against me..."
Now Kuper's haunted by the thought that Hume could get out of jail.
"I don't want him out. I don't ever want him out," said Kuper.
However, Hume's attorney, Sam Talley, says Hume is not a danger.
"He's not a threat to me. I'll tell you that the doctors will make the decision on whether or not he's a threat to the public. Which it will ultimately rest on the judge and what her opinion is of the doctor's opinions," said Talley.
Kuper sends a message to that judge.
"He needs to be on medication. He needs to be locked up the rest of his life, because if they let him out, he'll quit taking medication," said Kuper.
