An inquest into the death of a school girl from Suffolk has found she died of natural causes.
15-year-old Lily Grace Webster suffered a heart attack while trampolining at Mid Suffolk Leisure Centre in January.
Coroner Dr Peter Dean concluded she died of sudden adult death syndrome, and that there were no suspicious circumstances.
Sudden adult death syndrome affects about 500 people a year and is thought to be a genetic defect.
Lily Webster was a year 11 pupil at Stowmarket High. She was taking part in a trampolining session at Mid Suffolk Leisure Centre in January when she collapsed. An ambulance was called but she was pronounced dead at the scene.
Lily was described as accomplished on the trampoline. Scores of friends, including some who were there when she died, paid tribute to her on Facebook.
In a statement issued shortly after the tragedy, her family said: "Lily was a wonderful daughter and much-loved sister, niece, granddaughter, and friend to many.
"We have been overwhelmed by the kindness and the response of our local community. Her sudden loss is a terrible pain for us all to bear."
The inquest was held in Bury St Edmunds.
