PHILADELPHIA (AP) — Harrowing portraits are emerging of the victims of a Philadelphia group that allegedly took in the downtrodden and disabled for their Social Security checks, then held them captive in wretched conditions.The victims include a mentally challenged man chained to a basement boiler, a disabled woman with her teeth knocked out and a malnourished teenage niece with burn marks and pellet gun wounds.Accused ringleader Linda Ann Weston, her daughter and two men are charged with kidnapping, assault and other charges. Police believe Weston kept the victims in several states over the past year.Police Commissioner Charles Ramsey says he's never seen more severe injuries than those found on the 19-year-old niece, Beatrice Weston.Weston is being held on $2.5 million bail. Her lawyer has not returned calls for comment.
