The police report described a nightmare scenario in which Ms. Berry, Gina DeJesus and Michelle Knight were taken to Mr. Castro’s home and chained in the basement. Although the chains were later removed and they moved upstairs, they were all forced to have sex with Mr. Castro, the women told police.

Ms. Knight told police she had become pregnant five times, with Mr. Castro starving her and punching her in the stomach each time until she miscarried, according to the report.

Ms. Berry told police she had given birth to her daughter, Jocelyn, in a plastic pool. Ms. Knight described delivering the baby and reviving her at one point with mouth-to-mouth resuscitation, under threat of death from Mr. Castro if she let the child die, according to the report.

Ms. DeJesus also said she had sex with Mr. Castro, but told police she didn’t think she had become pregnant.
