TALLAHASSEE, Fla. (AP) - Experts say that when prosecutors announce criminal charges Wednesday in the hazing death of a Florida A&M University band member, they will embark on a legal chess game involving multiple defendants who require different approaches for winning convictions.

Prosecutors have prepared at least five separate cases against the suspects who contributed to 26-year-old Robert Champion's death aboard a chartered bus parked outside an Orlando hotel last November. Detectives say Champion was hazed by other band members following a performance against a rival school.

Witnesses told emergency dispatchers that Champion was vomiting before he was found unresponsive aboard the bus.
