Holly Stuckey, dead at 12
Holly Stuckey, of Bridgend, South Wales, who suffered from asthma, died after coming home from Maesteg Comprehensive School complaining of chest pains.
While her death is not being treated as suspicious, police are looking at the circumstances surrounding it.
After she died, Holly's parents, Clive and Lee, found hidden letters written by their daughter, giving details of months of misery.
Her father, a care worker, passed copies of the letters to police with the names of 13 children he claims were involved in her torment.
Keith Edwards, chairman of school governors, said police have "categorically" ruled out bullying as a factor in Holly's death.
"Obviously, these people are really, really hurting. It is such a tragic thing to happen to a 12-year-old girl. We have the greatest of sympathy for them," he said.
"As a school, bullying was never something flagged up to us. It is impossible to react to something that you do not know about."
He described Holly as a "lovely, lovely child" whose death had upset everyone at the school.
"But the police have said that there is no link to bullying in any shape or form. They have looked at the letters. I looked at one of them myself yesterday morning."
He said the letter he had seen seemed like "quite a morose song" and songwriting was something for which Holly was know to have a talent.
He added: "Of course, bullying does happen in all schools. Children can be very cruel, unfortunately.
"But it can often take place outside the school, going and coming, and that is not something we can ever see.
"But this is such an unbelievable tragedy."
