Ohio kidnapper Ariel Castro claimed he spoke to mother of one victim

Kidnapper Ariel Castro claimed to have called the mother of one of his victims while her daughter was in captivity, according to a videotaped interrogation in which he also claimed authorities missed opportunities to capture him.

Revelations of the decade-long kidnapping and repeated rapes of three young women shocked Americans when the women escaped from Castro's home in May. Castro, 53, was a month into his life sentence for the crimes when he killed himself on Tuesday.

In the video obtained by NBC, Castro said that he called the mother of Amanda Berry using Berry's mobile phone.

"I think I said something ... that I have her daughter and that she's OK, and that she's my wife now - something like that, you know, probably not the exact words," he told investigators.

When asked for the mother's response, Castro said, "I hung up, so we didn't have a conversation." Berry's mother died before Berry escaped.

Castro's captives - Berry, Gina DeJesus and Michelle Knight - disappeared separately between 2002 and 2004, when they were 14, 16 and 20.
