The Los Angeles County Sheriff's Department has released still images and composite sketches culled from more than 100 hours of video footage showing disturbing scenes of four men sexually assaulting at least 10 disabled women.
The assaults came to light, when a bundle of 11 DVDs were dropped off by an anonymous tipster at the sheriff's Monterey Park substation. Some of the footage is believed to have been taken from surveillance cameras, while other footage was likely shot by accomplices using hand-held cameras.
