Investigators are collecting evidence as they try to get a better understanding of the nightmare on Seymour Avenue in Cleveland.
FBI sources describe 10 years full of pain and torture. The back of the home was covered in tarps. The basement windows were covered with garbage bags. Wooden barriers made a sound-proof room.
Amanda Berry, Gina DeJesus and Michelle Knight were chained, beaten and raped.
"It's a long time and for them to come out of there safe, and they appear physically to be well, it's a miracle," said Cleveland Police Chief Michael McGrass.
Detectives were in and out of the home all Tuesday evening collecting evidence. K-9s sniffed for clues. Police searched the homes of all three Castro brothers.
Meanwhile, specially-trained interviewers are talking with the women, hoping to get information on how they were abducted, if anyone else was involved and details of the condition of the captivity.
But on Tuesday night, joy for the women rang out all over the neighborhood.
The chains were broken and 10-year-old mystery was solved.
