The last of the three Cleveland women rescued after being held captive for a decade left the hospital Friday. Michelle Knight had been in the hospital receiving mental health treatment since she was freed Monday, her mother said earlier this week. It was not clear where she was heading after leaving the hospital. Knight, Gina DeJesus, Amanda Berry and a 6-year-old daughter whom Berry bore in captivity — and whom DNA tests confirmed was suspect Ariel Castro's daughter — were freed Monday night after what authorities said was a decade of imprisonment. Of the three, Knight, 32, was reported missing first, in August 2002. She told investigators that Castro, charged with kidnapping all three women, impregnated her at least five times, starved her and punched her in the stomach until she miscarried, according to a Cleveland police report. But even as the parents of the three women rejoiced at the reunion, the mother of another girl who disappeared in 2007 and has not been found said she's "sad that it wasn't my daughter" who surfaced this week.
