An FBI agent from our Evidence Response Team in Cleveland watches as the house where three women were held captive for more than a decade by Ariel Castro is demolished on August 7, 2013. The home was torn down as part of a plea agreement that spared Castro a possible death sentence; Castro was sentenced to life in prison without the possibility of parole last week. In the decade leading up to the rescue, the FBI worked hard with its partners to locate the missing women, following every lead and helping to publicize the kidnappings. Since their heroic escape from captivity, the FBI has assisted in numerous ways, lending its investigative, evidence response, behavioral, tactical, victim assistance services, and other capabilities to the investigation, which was prosecuted locally.
