Caitlin Edwards, 13, dies of motorbike injuries
The family of a 13-year-old girl who died in hospital following a fall from a motorbike have paid tribute to her.
Caitlin Edwards, from Merthyr Tydfil, died last Friday at the University Hospital of Wales, Cardiff, after the fall 12 days earlier.
Her parents described her as "not only a wonderful daughter but a sister and friend all rolled into one."
A 40-year-old man who was riding the bike when it hit a stationary car remains stable in hospital.
South Wales Police said Caitlin was riding pillion on a Suzuki Bandit motorbike which hit a stationary Chevrolet Matiz at about 19:25 BST on Sunday, 27 May.
The incident was at the junction of Lower Thomas Street and Alma Street, Merthyr.
Both Caitlin and the bike's rider were taken to Prince Charles Hospital in Merthyr with serious injuries.
Caitlin, who had lived in Merthyr all her life and attended Cyfarthfa High School, was transferred to hospital in Cardiff for specialist treatment.
In a tribute released via South Wales Police, Caitlin's family said she was "always involved in school activities which included drama and dance".
Her parents added: "Caitlin loved helping others and that is why the decision has been made to donate her organs because we know that Caitlin would have wanted to help others in that way."
Her father said: "Caitlin was always proud of our relationship and very loving towards everybody in her family."
Caitlin's grandmothers, Shirley and Lisa, said: "She was bubbly, happy and the most wonderful granddaughter any person could wish to have - a ray of sunshine all year round."
Caitlin's stepmother, Pyuja, said: "Caitlin was a beautiful princess and young lady.
"Her younger half-sister would look up to her because she was so kind, well-mannered and always thoughtful of other people's feelings."
Hundreds of Caitlin's friends, including school classmates, have left tributes on social networking sites created in her memory.
One friend said: "She was just the best fun, talented, clever - it's heartbreaking because she had such a great life ahead of her".
An inquest will be opened by the Cardiff coroner later this week.
Officers investigating the incident are appealing for witnesses or anyone who has any information to come forward.
They are urged to contact the Roads Policing Unit via 101, or the independent charity Crimestoppers on 0800 555111.
