ORLANDO, Fla. -- The parents of a Florida A&M University drum major are concerned because the investigation into his hazing death three months ago in Orlando has not produced any arrests.

The attorney for Robert Champion Sr. and Pamela Champion says they're worried because charges have been filed in two other FAMU band hazing cases that were less serious. The younger Robert Champion died in November after he was beaten aboard a band bus.

It's not unusual for a homicide investigation to take three months or more. Some complications in this case are that many witnesses live outside the Orlando area, and not all are cooperating.

Investigators also didn't get to work the crime scene because Champion's death wasn't declared a homicide until a month after he died.
