Man sentenced for manslaughter through diminished responsibility

A 32-year-old man has been sentenced for manslaughter through diminished responsibility, after he stabbed his stepfather in his own home.

Adejuwon Olufemi Alexander Jnr Oyekan, 32 (08.11.1992) of Melina Close, Hayes, was sentenced to a hospital order until deemed fit for release, on Thursday, 10 April at the Old Bailey. He had previously pleaded guilty to manslaughter through diminished responsibility at the same court on Monday, 24 February 2025.

Officers were called to a residence in Hayes in the early hours of Tuesday, 11 July 2023, to reports Oyekan had stabbed his 54-year-old stepfather Jason Thompson.

When they arrived, officers were faced with Oyekan still armed with the knife which he had used to attack Jason.

After the first responding officers had gained entry to residence they challenged Oyekan, initially using their tasers in an attempt to disarm him. When this was unsuccessful, they then left the address to await support from armed response officers to detain him.

When officers returned to the property, they made it their priority to assist Jason. However, sadly and despite the best efforts of the emergency services, Jason died from his injuries at the scene.

Barbara Thompson, sister to Jason Thompson:

“Jason and I had a special bond. We were both cheerleaders for one another and revelled in each other’s good news and growth. Equally, his love for family and life was authentic and abundant.

"There is not a day that goes past without tears and my heart aching. I still struggle with the reality that he’s not here. I struggle with the violence he endured. I struggle with the unfairness of my brother being taken so tragically.

"Jason leaves behind a beautiful, attentive and caring legacy and I and so many others thank him for the beautiful memories, care and love he provided.”

Detective Chief Inspector Laura Semple from the Met’s Public Protection Partnership, said:

“Our thoughts remain with Jason’s family throughout this difficult time”

“I’d like to thank the first responding officers who attended the scene and demonstrated huge bravery to challenge Oyekan, who was armed and acting aggressively.

“Their quick thinking, to use the tools at their disposal, guaranteed Oyekan was admitted to custody from the scene, and did not go on to pose a wider threat to the public.”

“Oyekan will now be detained under a hospital order until he is deemed fit for release, meaning he will no longer be a risk to the public.”

Oyekan was arrested at the scene and charged with murder on Wednesday, 11 July 2023.
