A coroner has concluded that a respectful and kind-hearted teenager died from cold water shock after getting into difficulty during a spontaneous night-time swim with friends in Plymouth.
The Tragic Night Swim
Michael Oppong-Yeboah, an 18-year-old environmental science student at the University of Plymouth, vanished during an evening dip with around ten friends from a jiu jitsu society in March 2024. The group had entered the water at East Hoe beach.
The inquest at Exeter Coroner's Court heard that Michael swam a short distance into rough conditions before beginning to tread water. Witnesses reported hearing him shout for help after being struck by a large wave, after which he disappeared from view.
Assistant coroner Ian Arrow stated the student succumbed to cold water shock, a physiological reaction which severely impairs a person's ability to swim and stay afloat. His body was recovered from the water at Devonport naval dockyard two weeks later.
A Life Full of Promise
In a heartfelt tribute, his mother, Doris Kyeremaa, described Michael as a very respectful, kind-hearted, humble, and God-fearing individual who loved the company of others. "He always made sure to put others' happiness first," she said.
Michael was a former pupil of Chater Infant and Junior Schools in Hertfordshire and Westfield Academy. He had worked as a lifeguard at Watford Leisure Centre, loved swimming, and was a great help at home. His mother also highlighted his volunteer work at the Watford food bank (Macs Clinic), where staff spoke highly of his good behaviour.
He was remembered for his infectious smile, love for children and animals, and his passion for cooking and sharing jokes to make people happy.
Coroner's Stark Warning
Concluding the inquest, Assistant Coroner Ian Arrow issued a public safety warning. He expressed hope that the publicity surrounding Michael's death would make people aware of the very great danger of entering cold and rough seas, particularly at night.
This tragic case underscores the hidden risks of open water swimming, even for those, like Michael, who were strong swimmers and trained lifeguards. Cold water shock can incapacitate even the fittest individuals within moments.
