A mother accused of murdering her severely disabled son called a friend to tell them what she had done, an inquest has heard.
Ten-year-old Dylan Freeman, who had autism and Cohen syndrome, was found dead at his home in Acton, London, on 16 August.
West London Coroner’s Court on Tuesday heard Dylan died after his airways were restricted.
His mother and primary carer, Olga Freeman, appeared at the Old Bailey last week accused of his murder.
Senior coroner Chinyere Inyama said Ms Freeman had recently been prescribed antidepressant tablets.
He added: “[Dylan’s] mother called a friend in the early hours to state to the friend that she killed her son.”
Mr Inyama said the mother and her friend went to Acton police station in west London and told them what had happened.
Police and paramedics went to Dylan’s home in Cumberland Park, where he was found dead.
The coroner said it appeared he had been administered a sleeping aid.
His body was identified four days later by his headteacher.
