missing Ohio Sisters

Cleveland kidnapper Ariel Castro's death by hanging in his prison cell may not have been suicide after all, but an attempt to choke himself for a sexual thrill, authorities said Thursday.

The case in Ohio, in which three women were found alive on Monday after nearly a decade after they went missing, is giving many families a renewed hope that one day they may find their missing loved one. Unfortunately, cases like these are not the norm.

One neighbor says a naked woman was seen crawling on her hands and knees in the backyard of the house a few years ago. Another neighbor says he heard pounding on the doors and noticed plastic bags over the windows.
