Alfie Conway-Ryle has been convicted of murder after a brutal attack in Southwark Park left his victim in a coma — and ultimately denied the 66-year-old man the chance of life-saving cancer treatment.
Conway-Ryle, 26, of Ilderton Road in Southwark, was found guilty at Croydon Crown Court on Wednesday of the murder of William Ffrench, known to friends and family as Owen. The verdict ended an investigation that stretched more than two years and hinged on medical evidence linking a single violent night to a death that came nine months later.

What happened in Southwark Park
Officers were called to Jocelyn Street, SE15, in the early hours of 27 June 2024 after reports of a serious assault. CCTV footage from the park showed Conway-Ryle and Owen in an altercation near Surrey Canal. The court heard that as Owen repeatedly pleaded to be left alone, Conway-Ryle told a bystander he intended to kill him.
Conway-Ryle then deliberately tripped Owen to the ground and repeatedly stamped on his head. More than 15 stamps were inflicted over a period of about 40 seconds, the court heard. When officers arrived, Owen was unconscious. He was taken to hospital with multiple brain bleeds, extensive facial fractures and broken ribs. Witnesses at the scene identified Conway-Ryle, who was arrested there.
He was charged with attempted murder on 28 June 2024 and pleaded not guilty. He was remanded into custody while awaiting trial.
Cancer treatment denied by catastrophic injuries
Owen never regained consciousness. Months later, in December 2024, doctors diagnosed him with lung cancer. Medical professionals examined whether treatment was possible, but concluded that the devastating brain injury from the assault had left him too unwell to tolerate it — and unable to consent to it.
Without cancer treatment, and carrying the injuries from the assault, Owen died on 9 March 2025.
Detectives then faced an unusual task: proving that an attack carried out nearly nine months earlier had materially contributed to his death. Working with Owen’s treating clinician, an expert oncologist, a neuropathologist and a forensic pathologist, investigators built a detailed picture of how the injuries had deprived him of potentially life-saving care. In February 2026, Conway-Ryle’s charge was upgraded from attempted murder to murder.
Why the medical evidence mattered
Under English law, a murder conviction does not require the assault to be the sole cause of death — the prosecution must show it made more than a minimal contribution to it. That principle was central to this case.
The investigation established that the injuries Conway-Ryle inflicted had long-term consequences far beyond the night of the attack: they left Owen in a condition where treatment for cancer diagnosed months later was impossible, directly connecting the assault to his death.
Detective Inspector Richard Mackenzie, who led the investigation, said the evidence was instrumental in proving the assault had fatal consequences long after the attack itself.
“The investigation did not end with Owen’s assault. Following his death, detectives were faced with the complex and unique task of understanding the long-term impact of the injuries inflicted by Conway-Ryle. Working alongside a range of specialist medical experts, we established that those injuries left Owen unable to receive treatment for cancer diagnosed months later, denying him the opportunity of potentially life-saving care.”
He added that the family had endured “an unimaginably long and painful journey” since the attack, and expressed the hope that the verdict would hold Conway-Ryle accountable for what he called the devastating consequences of his actions.
Family tribute to “beloved uncle”
In a statement, Owen’s family said justice had finally been served for their “beloved uncle”, thanking the legal team, police and every professional who had fought to bring the case to court, as well as the family members who sat in the courtroom every day of the two-week trial.
“My uncle was the life and soul of this family, teaching us all how to live life and enjoy every single moment. He was somebody’s son, somebody’s brother, and a truly loving, caring, and selfless man who had endless time for every one of us.”
The family said they had never got the chance to say goodbye — “You didn’t wake up, the moment you were taken into the hospital, you didn’t wake up” — and that while nothing could fill the void left by his loss, “justice has been served”.
