Wrestling students from an Arizona high school have been accused of hazing and bullying a fellow student.

Robert Champion was known for his opposition to the hazing rampant in the Florida A&M University marching band, but band mates claim the gay student volunteered to be hazed.

The inability to pinpoint which blow ultimately caused Robert Champion, 26, to die led authorities to charge 13 defendants Wednesday with hazing rather than more serious counts like manslaughter or second-degree murder.

At least five people will face criminal charges in the hazing death of a gay Florida A&M University drum major aboard a band bus in Orlando last fall, authorities said Tuesday.
