CLEVELAND -- A DNA test confirmed another dark twist in the story of three women imprisoned in a house for about a decade: Kidnapping and rape suspect Ariel Castro is the father of a 6-year-old girl who escaped from the house along with the women, a prosecutor said Friday.
As the investigation into the women's ordeal continued, the FBI also said no human remains were among more than 200 pieces of evidence collected from the house.
Two of the women returned to relatives' houses earlier this week. The third woman, Michelle Knight, was released from a hospital Friday with a request that her privacy be respected.
"Michelle Knight is in good spirits and would like the community to know that she is extremely grateful for the outpouring of flowers and gifts," the statement said.
Castro, accused of holding the women captive, remained in jail under a suicide watch and on $8 million bond while prosecutors weighed what charges they might bring against him, including the possibility of charges carrying the death penalty. He already is charged with rape and kidnapping.
A police report alleged that Castro impregnated one of his captives at least five times and made her miscarry by starving her and punching her in the stomach.
Tests by the state attorney general's office on a sample of Castro's DNA confirmed that he is the father of kidnap victim Amanda Berry's 6-year-old daughter.
Officials also were entering the DNA profile into a national database to see whether it links Castro to other crimes.
