Investigators allege the six teens punched and kicked the 48-year-old Chester woman and hit her with a shoe and a chair in September, apparently for fun. One recorded the beating, which was posted online.
The Delaware County Daily Times reports 16-year-old Janyea Bell pleaded guilty to charges of conspiracy to commit aggravated assault and conspiracy to recklessly endanger another person. She's sentenced to 6 to 23 months in prison.
Bell apologized to the victim's family in court Tuesday. Two other juveniles and a 19-year-old woman have also been sentenced to prison in the case.
The remaining defendants are seeking to have their cases moved to juvenile court.
