With his legs in shackles, 16-year-old Brad George faced court after he allegedly confessed to murdering the woman who provided him with a home for over a decade.
He was ordered to be jailed in lieu of $500,000 cash-only bail during a brief hearing in the Snohomish County Superior Court in Washington, USA.
It comes just one day after a teary-eyed George fronted television cameras and questioned who could have committed such a crime, where he allegedly crept into his mother's room and bludgeoned to death with a dumbell in her bed last Thursday night.
His mother, Georgina Latshaw, was found dead in her bed with blunt-force trauma to the head, according to the police report.
He then called 911 and told responding officers that he had found the front door or their apartment open when he returned home from school and was too afraid to go inside, police say.
"The door was open and her car was home and that never happens," George told Kiro TV as he gave a chilling interview alongside his sisters.
"It is 15 degrees outside and my neighbours says the door has been like that for a while and I thought that was very suspicious."
"So I called the house phone and no one was answering and I called 911."
"The police arrived and went upstairs and they came down and told me that my mum had passed away."
"She has supported me my whole life. She always knew what was best for us. I don't know who could have done this."
"This doesn't feel real, this all feels fake."
The 16-year-old reportedly told police he had stopped taking medications since February 1 and had not slept in three days, according to the MailOnline.
He allegedly told police he though his adoptive mother was trying to poison him with bleach and was acting in self-defence when he decided to kill her.
According to police, George became violent during an evaluation at a psychiatric hospital, pulling a wooden arm off a chair and raising it at a nurse ready to strike as he walked toward her.
He was disarmed by two security guards after the nurse screamed for help, according to MailOnline.
In keeping with state law, the seriousness of the allegation requires George’s case to be handled in the adult legal system, prosecutors said.
