Tillman was arrested in Montgomery in March while visiting her aunt at Jackson Hospital. Hospital surveillance video of the arrest was released Friday. Tillman's daughter said she hopes the video will help their case.
Tillman claims she was "brutalized" by police after a dispute over her aunt's medical records. She says she suffered bruises when officers knocked her to the ground.
Montgomery police deny mistreating her.
Tillman is charged with criminal trespassing.
