A fatal beating that began as a welcome to the famed Florida A&M marching band and became a symbol for the anti-hazing movement has resulted in expanded charges.

Twelve former band members now face charges of manslaughter in the 2011 death of drum major Robert Champion.

The new charges were announced at a hearing Monday. Last spring, 10 band members were charged with third-degree felony hazing. A conviction could result in a prison term of up to six years; the additional charges can mean up to 15 years in prison.

State Attorney Jeff Ashton also filed charges against two more band members.

Champion's parents, Pamela and Robert Champion Sr., have sued the school and other parties.

FAMU issued an e-mail statement Monday saying, "Due to the pending civil litigation, the university has no comment at this time."
