Cleveland kidnap: Amanda Berry's daughter was born in an inflatable pool inside the 'house' Suspected captor Arial Castro used chains hanging from the ceiling to keep the girls inside the Cleveland home for the first few years Local police sources say he would beat them in the stomach if they became pregnant, forcing them to miscarry Used psychological games to 'train them' not to try to run free By Daniel Bates In Cleveland, Ohio and Rachel Quigley Amanda Berry gave birth to her six-year-old daughter in a small inflatable swimming pool while she was being held in captivity at the house of Ariel Castro, it emerged today. Police sources confirmed today that chains, ropes and other bondage devices were found in the house on Seymour Avenue and that at least one of the girls was chained to the wall 'like a trophy'. It also emerged today that Castro would sometimes sneak the women out of the house in disguises and multiple sources confirmed that Berry's daughter Jocelyn was taken out often to visit her 'grandma' and be home schooled. A source with access to a police report told The Plain Dealer that while the women were chained and locked inside different rooms in the home, holes were cut in the doors to slide things like food in and out. Another police source told a local news station that what they found in the house confirms that the victims endured a decade of torture at the hands of Castro. It was also revealed that Castro would use a sick game to 'train' the three girls not to run away by pretending to leave the house, only to beat them if they tried to run free. The trick clearly contributed to the young women's captivity, as Berry stressed the fact that she feared his quick return during her frantic 911 call. The hanging chains were also reportedly used during the first few years of captivity, along with frequent beatings. 'They were bound and gagged several times throughout the course of being held in that home,' WOIO reports. Another psychological tactic that he used to keep the women in constant fear was the constant threat of violence, and threats to their childrens' lives. In hindsight, there were signs of a darker side to Ariel Castro. Divorced years ago and never seen in the company of women, he suddenly started showing up in the largely Latino, working-class neighborhood with a little girl. It was his girlfriend's child, he told neighbors. The 52-year-old was believed to have lived alone, yet on his lunch break would bring home enough bags of fast food and beverages for several people. He was a school bus driver given mostly 'excellent' marks on his performance appraisals, but was repeatedly disciplined, including for one incident when he was accused of calling a young student a 'bitch' and leaving a child alone on a bus. He was fired last November. Castro was arrested in 1993 after a domestic violence complaint, though a grand jury decided not to indict him. Another complaint in 2005 filed by his ex-wife, who died last year at age 48, accused him of twice breaking her nose and attempting to abduct their daughters and keep them from her mother. Knocked out tooth. Dislocated shoulder (twice - one each side); threatened to kill petitioner and daughters 3/4 times just this year,' the petition, signed by Figueroa and her lawyer, said. For years, Castro's neighbors on Seymour Avenue saw him as a friendly but private person, an accomplished musician who played bass in Latin bands such as Borin Plena and Grupo Fuego. He liked motor-bikes and showed up at neighborhood barbecues in a vacant lot on Seymour Avenue. He was a self-taught mechanic who loved to talk about cars. He owned an unremarkable, two-story house in a somewhat dilapidated part of Cleveland. Built in 1890, the home was valued at a mere $13,200 in 2011, according to property records. Its windows were covered to block views from the outside. One childhood friend said a music session with Castro, who was born in Puerto Rico, suddenly turned bizarre. Ariel was in my garage probably five or six years ago. We were recording a song, an idea we had - a little hard rock with some Latin,' said Joe Popow, 45, a father of six who said he has known the Castro brothers since childhood. 'And - you're going to laugh - he said he was in the CIA. And I don't know if he was joking or not, but it's the way he said it, how serious he said it. 'I didn't know what he was capable of. That just put me on defense, and I just started stepping away,' Popow said. Signs: In a photograph taken in 2001, suspect Ariel Castro stands with a former girlfriend in front of a padlocked door, which led to the basement, at his home on Seymour Avenue, Cleveland While Berry is said to have birthed her six-year-old daughter Jocelyn during her captivity, police are reportedly looking for the bodies of other children who were miscarried or died due to malnutrition. 'Numerous times throughout this 10-year period, that some of the women became pregnant and that they would be beaten, forcibly hit in the stomach to force a miscarriage, if you can imagine that,' WOIO reporter Deroos told CNN. Jocelyn, like her mother, was said to be dehydrated and malnourished, but eventually given the all-clear by a local hospital following their rescue. Other children are thought to have suffered a different fate, as cadaver dogs were brought to the house by investigators searching for the bodies of any other children. The ongoing investigation of the house has led investigators to believe that while the girls were kept on the property by the boarded windows, padlocked doors, and chicken wire-laden fence, they may have been able to access multiple rooms inside the home. The house is now the center of an FBI investigation after Berry, 27, DeJesus, 23 and Knight, 30, were all found there after being missing for around ten years.
