(WMMS - Cleveland) - One of three women held captive in a Cleveland home for a decade has appeared at a public event for the first time since her rescue, a day after her abductor pleaded guilty in the case. 

Amanda Berry made a surprise appearance at the daylong concert Roverfest in Voinovich Park Saturday night. 

The 27-year-old Berry walked on stage with her family and waved at the cheering crowd. The rapper Nelly called Berry back to the stage after his music set. 

Berry waved to the crowd and smiled as people responded with cheers of support. She did not speak. 

Ariel Castro pleaded guilty Friday to imprisoning Berry, Gina DeJesus and Michelle Knight and subjecting them to rapes and beating for a decade. 

The plea deal will keep Castro imprisoned for life.
