CLEVELAND -- NBC News has obtained interrogation video of Ariel Castro being questioned just hours after his arrest. During the questioning he makes some stunning revelations.
Castro told interrogators that he used Amanda Berry's cell phone to call her mother.
"I think I said something, that I have her daughter and that she's OK and that she's my wife now," Castro is seen saying in the footage. "Something like that, you know, probably not the exact words."
Castro claimed he then hung up on Berry's mother without further conversation.
That admission is just a small portion of the four-hour interrogation video, which was obtained exclusively by NBC News.
Snippets of the interrogation video aired Friday morning on the "Today" show.
The video also features Castro explaining to investigators how he abducted Berry, Gina DeJesus and Michelle Knight.
At one point, Castro reveals how he thought he was going to be caught after abducting DeJesus because surveillance cameras in the area likely captured him on film just 15 minutes prior.
Castro also discussed with investigators details about the day the three women escaped his house of horrors on Seymour Avenue in May.
"I know I let my guard down," Castro says while disclosing how he had left a bedroom door unlocked.
At one other point in the video, Castro told investigators how his daughter pleaded with him to unlock doors in the home.
The video also shows Castro being led out of the Justice Center for transport to prison.
Castro killed himself behind bars earlier this week -- just one month into his life sentence.
He previously pleaded guilty to more than 900 counts against him.
Police arrested Castro on May 6. That was the day Amanda Berry broke out of the house and made a call for help. The women disappeared between 2002 and 2004.
