A police complaint says Rice struck her with his hand, “rendering her unconscious.” Palmer is also accused of striking Rice with her hand.

Palmer’s attorney, Robert Gamburg, said Thursday he’s certain neither person committed a crime. Rice’s attorney, Michael Diamondstein, has said he hopes the case is shown to be a misunderstanding.

TMZ Sports released a video of what it says shows Rice dragging a seemingly motionless woman out of a Revel Casino elevator.

Diamondstein told The Press of Atlantic City “this is obviously edited video.” Neither he nor Palmer’s attorney would comment about the video to The Associated Press.

CNN has the video and some additional details:
