Fourth Pa. teen girl sentenced to prison in videotaped beating of mentally disabled woman

(CBS/AP) MEDIA, Pa. - A fourth teenage girl was sentenced to prison Tuesday in the videotaped beating of a mentally disabled woman near Philadelphia.

Investigators said six teens punched and kicked a 48-year-old woman from Chester, Pa. as she sat on her stoop in September 2012. They hit her with a shoe and chair, apparently for fun. One recorded the beating, which was posted online.

Janyea Bell, 16, pleaded guilty to charges of conspiracy to commit aggravated assault and conspiracy to recklessly endanger another person, according to the Delaware County Daily Times. She was sentenced to 6 to 23 months in prison.

Three other people were previously sentenced to prison in the case. The remaining defendants are seeking to have their cases moved to juvenile court.
