Man Found Guilty of Murder After Brutal Park Attack Left Cancer Victim Unable to Receive Life-Saving Treatment

A man has been found guilty of murder after a brutal assault left a 66-year-old victim with catastrophic brain injuries, preventing him from receiving potentially life-saving treatment for cancer diagnosed months later. The case has highlighted the devastating consequences of a violent attack that continued to affect the victim long after the incident itself.

William Ffrench, known affectionately to his family and friends as Owen, was attacked by Alfie Conway-Ryle in Southwark Park, London, in June 2024. During the assault, Conway-Ryle repeatedly stamped on Owen’s head, inflicting severe injuries that left him in a coma. Owen suffered multiple brain bleeds, extensive facial fractures and broken ribs, and he never regained consciousness.

Owen remained in hospital for months following the attack. In December 2024, medical professionals discovered that he had lung cancer. However, his condition was so serious that doctors determined he was too unwell to undergo cancer treatment. The brain injuries sustained during the assault had left him unable to consent to treatment and unable to tolerate the care that might otherwise have offered him a chance of survival.

Owen died on March 9, 2025, without ever regaining consciousness. He was 66. Following his death, detectives launched a murder investigation to establish whether the injuries inflicted during the park attack had contributed directly to his death. Investigators worked alongside medical specialists, including an oncologist and forensic experts, to understand the connection between the assault, Owen’s deteriorating condition and his inability to receive cancer treatment.

The investigation ultimately established that the injuries had deprived Owen of the opportunity to receive potentially life-saving care and had contributed to the fatal outcome. Conway-Ryle’s charge was upgraded from attempted murder to murder in February 2026. On October 14, 2026, he was found guilty of Owen’s murder at Croydon Crown Court. He is due to be sentenced on December 4.

In a moving tribute following the verdict, Owen’s family said justice had finally been served for their beloved uncle. They described him as the life and soul of the family — a loving, caring and selfless man who encouraged those around him to enjoy every moment of life. The family said they wished they could have had one more moment with him to tell him how deeply he was loved, adding that they never had the chance to say goodbye.

Detective Inspector Richard Mackenzie, who led the investigation, said the case required detectives to examine the long-term consequences of the assault. Working closely with medical experts, investigators were able to demonstrate that Owen’s injuries had prevented him from accessing cancer treatment and had ultimately played a role in his death. He acknowledged the long and painful journey endured by Owen’s loved ones, noting that while no verdict could undo their loss, the outcome held Conway-Ryle accountable for the consequences of his actions.

For Owen’s family, the verdict marks the end of a long legal battle, but it cannot erase the loss of a man they described as deeply loved and irreplaceable. Their tribute made clear that, beyond the court proceedings, the case is ultimately about a family remembering someone whose life was cut short by a violent act.
