ATLANTA -

The parents of a Florida A&M drum major who died during a hazing ritual say they are disappointed by the school's response to a lawsuit they filed in their son's death.

Pam and Robert Champion Sr. said Thursday at a news conference in Atlanta that court documents filed Monday show FAMU is not taking responsibility for the safety of its students.

The university filed a motion asking a judge to toss the lawsuit filed against it by Champion's family on Monday, saying Champion knowingly and willingly participated in the hazing ritual that led to his death.

The Champions described the response as a slap in the face and that they trusted the university to keep their son safe.

"They clearly didn't care about my son, who thought the world of the school, who would always promote it and talk it up," said Pam Champion. "Robert did all the right things, the school didn't do right by him."

Chris Chestnut, the lawyer representing the Champions, said this is not about Robert Champion, that it's about the safety of students.

Robert Champion died last November after he was beaten by fellow members of the famed Marching 100 band aboard a charter bus parked outside an Orlando hotel.
