COLUMBIA, S.C. (AP) – The mother of a fifth-grader who died after a fight at her South Carolina elementary school says other students in the class say her daughter hit her head on a bookshelf.

Ashley Wright told Good Morning America that she is frustrated by the lack of answers after her 10-year-old daughter Raniya died in the hospital two days after the March 25 fight at Forest Hills Elementary School in Walterboro.

School officials have released few details, saying the criminal investigation is ongoing. The other fifth grader involved has been suspended.

State Sen. Margie Bright Matthews says she has talked to students and the families of both students and it was a small scuffle with Raniya appearing OK after the fight, then losing consciousness in the principal’s office.
