The main suspect in the Cleveland kidnappings is Ariel Castro, a 52-year-old former school bus driver.
It was a house of horrors where he allegedly kept four females captive for so many years. Neighbors say he always kept the blinds drawn and even boarded up a window so no one could look in.
Some residents knew Castro as the neighborhood nice guy.
Juan Perez told INSIDE EDITION, "I thought he was a great neighbor. I've known him since I was five years old. You know, in this community we don't have very many fathers, very many male role models. He seemed like a guy we could look up to."
Victim Amanda Berry spelled out her captor's identity in her desperate 911 call after she fled his home.
Berry: "His name is Ariel Castro."
911 Operator: "Ok. How old is he?"
Berry: "He's like, 52."
Castro has owned the house since 1992. According to one report, neighbors once heard someone pounding on a door of the home, and even saw a naked woman crawling in the yard.
Police actually went to the home in 2004 to speak with Castro after he left a kid on the school bus at the depot. They found nothing suspicious.
Castro's own son, also named Ariel, actually wrote an article for a community newspaper about the disappearance of Gina DeJesus in 2004, apparently unaware that his father allegedly had the girl chained in his home.
It said: "Gina's disappearance has the whole neighborhood talking...Residents have been taken by an overwhelming need for caution."
Castro even interviewed Gina's mother. He quoted her as saying, "It's a shame that a tragedy had to happen for me to really know my neighbors. Bless their hearts, they've been great."
And when the son posted a picture of him and his family on Facebook, Ariel Castro Sr. commented "Happy birthday to my grand baby. Love the flower on your hair...I love you! Xoxoxo."
Castro played bass guitar. Photos have surfaced showing him when he was in a band.
His last Facebook posting was on May 2. It said: "Miracles really do happen. God is good."
Castro's brothers, Pedro (left) and O'Neal (right) have also been arrested in the case.
When a Cleveland TV station did an earlier story on the search for the girls, Pedro had this reaction: "That's a waste of money."
Paul Boyd spoke to the men's uncle, asking, "Take me through what you're thinking and feeling."
"I have very high emotions on both sides. Being happy because they found the girls. Being sad because a member of my family was involved," said the uncle.
Criminal profiler Pat Brown told INSIDE EDITION, "It's very unusual that you actually have a whole family that is so creepy, that you would have three brothers that would actually kidnap girls and keep quiet about it for a decade. But you know, sometimes all of them have personality disorders and they support each other."
