The woman produced a video tape of sexual assault. She was 14 years old at the time of video. The singer sexually abused her "hundreds" of times before she turned 18.

Court officials set up high opaque screens around juror’s  chair to play the sexual videos.  Journalists and spectators were blocked from seeing the videos and jurors’  reactions. The sound was audible throughout the courtroom.

Assistant Attorney Jason Julien sought to give jurors a sense of the  scale of Kelly's alleged exploitation, saying he "repeatedly" had sex  with girls who were just 14, 15 and 16 years old — "multiple girls,  hundreds of times."
