New, first-hand testimony in the bus beating and hazing death of FAMU drum major, Robert Champion.

One by one, former band members testified against the three remaining men charged in the hazing ritual that killed Champion more than three years ago in Orlando.

The majority of the witnesses called to the stand were former band members, who were also charged in the hazing death of Champion.

They took plea deals years ago in exchange for their testimony - testimony that could land their former band mates in prison for 15 years.

Benjamin McNamee, Aaron Golson and Darryl Cearnel, are on trial for felony manslaughter and hazing.

In court, the prosecution produced witnesses that place all three of them at the scene of the crime, aboard a bus the night Champion was beaten to death in November 2011.

“I saw punching, I saw kicking, I saw grabbing and pulling," said Jonathan Boyce, a former FAMU member who took a plea deal in this case.

Another band member said during this hazing ritual known as Crossing Bus C, she saw McNamee jump over seats while swinging and kicking Champion all the way to the back of the bus.

“I describe it like a monkey trying to hop over the seats," April Denise Tarpley said.

But it was when Champion completed the ritual by making it to the back of the bus, that his injuries were too severe to survive.

“He was saying that he was short of breath, he could barely breathe," Boyce said. "Told me he couldn’t see.”

Band members testified Cearnel tried to revive Champion with CPR without success. When paramedics arrived, Champion had no pulse.

The trial is moving along quickly.

The state only has one more witness to call – the medical examiner.

Judge Renee Roche expects closing arguments to begin Thursday and then the case will be in the hands of the jury.
