Olga Freeman, 40, of Cumberland Park, Acton, pleaded guilty at the Old Bailey on Monday, 25 January to the manslaughter of 10-year-old Dylan Freeman by reason of diminished responsibility.
In the early hours of Sunday, 16 August 2020, Freeman attended Acton Police Station, where she stated that she had given Dylan some pills and pushed a sponge into his mouth.
Officers attended the home at around 2.16am and found Dylan unresponsive. Colleagues from the London Ambulance Service were requested and he was pronounced dead at the scene.
Freeman was arrested at 3.11am on suspicion of murder.
A post-mortem examination was conducted on 18 August at Great Ormond Street Hospital. It recorded a provisional cause of death as upper airway obstruction by a foreign body.
The court heard that Dylan suffered from extensive mental and physical health issues which impacted his independence and his ability to communicate.
Freeman had cared for him for many years, using local authority services and an acquaintance for assistance.
She had also suffered from mental ill-health and with challenges in her personal life.
She spoke to acquaintances about struggling with the responsibility of caring for Dylan.
Around 10pm on the night before Dylan was found, she sent a message to a friend stating: “I am done. Where are u?”
The friend arrived at around 12.44am and found that Freeman had booked two seats on a flight from London Luton Aiport to Tel Aviv. She said she had been receiving messages in her head. The friend was not allowed to go into Dylan’s room.
Shortly before 2.16am Freeman attended Acton Police Station with the acquaintance, and said to the officer on duty that she had killed her son.
She largely answered ‘no comment’ during police interviews.
Detective Chief Inspector Simon Harding, lead investigator, said: “This has been an incredibly sad incident to investigate. Foremost our thoughts are with Dylan and his family, who continue to feel his untimely loss and will do so for a long time to come.
“I would like to thank my team of detectives, who have worked so diligently and professionally during this harrowing case. I would also like to acknowledge the selfless actions of my response colleagues who attended the scene on that night and tried in vain to save Dylan’s life.”
A date for sentencing has not yet been set.
