The family of a Washington state girl injured when a gun in a classmate's backpack went off is suing the school district, saying it failed to heed clues the boy was dangerous.

Amina Kocer-Bowman's family filed a $10 million claim Wednesday against the Bremerton School District. The 8-year-old spent six weeks in the hospital, required numerous surgeries and suffered lifelong injuries when the bullet pierced her internal organs and lodged in her spine.

The claim says her teacher was concerned that the boy who brought the gun to school was acting out and fighting. It also says the boy had told several other children his intention to bring a gun to school.

The girl's family is also suing the boy's relatives for allowing him access to handguns.
