EAST DUBUQUE, Iowa - It's been a week since the arrest of an East Dubuque man accused of murdering of his missing stepdaughter, Chyenne Kircher.
His biological daughter told KCRG.com that she suffered abuse from the man she once called "dad" and she believes he may have also abused Kircher.
Last Wednesday, police arrested Terry Abbas,40. He's accused of strangling Chyenne Kircher. He's now in the Jo Daviess County Jail on two counts of murder.
Chyenne Kircher was 14 when she disappeared in October, 2011. Police initially thought she'd runaway from home. Last week, investigators found human remains they believe to be Kircher's body buried behind the family's East Dubuque home.They are waiting on autopsy results to confirm it is Kircher.
Sheria Chambers said her biological father, Terry Abbas, sexually abused her when she was just three-years-old. Chambers said it happened while she and Abbas lived in Chariton, Iowa. Police there investigated, but did not find enough physical evidence to press charges.
Chambers thinks if police had done more, Chyenne might still be alive. "Investigators had done a series of tests and put me in a room and gave me Barbies and told me to explain what happened," Chambers said.
Chariton Police reports show two experts found psychological evidence that Chambers was abused. Police and doctors did not find any physical evidence to charge Abbas.
According to court documents, the Department of Human Services also investigated and placed Abbas on it's "Central Abuse Registry". That means the organization deemed the abuse claim as "founded". Chambers said that's when her dad gave up custody and moved to East Dubuque.
Five years later, in 2004, he regained visitation rights. "It started off, you know, like a visitation. Supervised. It started off with my grandma," Chambers said. "And after awhile I guess they approved him to have visitation alone with us. And then there became overnights."
During those overnight visits in East Dubuque, Chambers said she met Chyenne Kircher. She said Kircher confided in her that Abbas was abusing her. ""I told her she needed to go find a teacher. She needed to go find somebody she trusted," said Chambers. "She needed to go tell somebody because I couldn't help her. "
Now with news that Abbas is accused of killing Kircher, Chambers said she wishes she could have done more. "She'd seen the consequences of telling him 'no'. So I think she was too scared to go ask for help."
Police in East Dubuque will not say if they've ever investigated claims that Abbas was sexually abusing Kircher. They also will not say if abuse claims are a part of the murder investigation.
