A McKeesport girl who went missing for 10 years argued in a court filing this week that the school district, local police and the security company that hired her abductor, Thomas Hose, all failed to do their jobs, which contributed to her abduction.

In a 100-page brief arguing against dismissal of her civil lawsuit against those parties and others, Tanya Kach said that school officials knew of her relationship with then-37-year-old Mr. Hose, but failed to do anything about it.

Mr. Hose pleaded guilty last year to holding Ms. Kach against her will for 10 years.

She went missing in February 1996 and resurfaced in March 2006. Mr. Hose pleaded guilty to involuntary deviate sexual intercourse and was sentenced to five to 15 years in prison.

According to this week's filing, Ms. Kach, who was 14 at the time, first met Mr. Hose when she was a student at Cornell Middle School. She had left wood shop class early, and he asked to see her hall pass.

They began to talk to each other more, she said, and he would walk with her to class.

Ms. Kach began calling Mr. Hose at his home in December 1995 and then started to visit him.

According to court papers, she recounted her personal problems to him, including that she'd been raped and had inappropriate sexual advances made toward her by a 20-year-old man.

"Plaintiff was already a psychologically troubled and abused youth prior to the events in question, and therefore particularly at risk for further abuse and control by any adult bent on subjugating her," her attorney, Lawrence H. Fisher, wrote.

Ms. Kach claims that Mr. Hose helped her run away several times, including giving her money and advice.

Further, she claims that she went to Mr. Hose with allegations that her home life was bad, describing physical abuse by her father's girlfriend as well as drug and alcohol abuse.

She said that St. Moritz Security Services, which hired Mr. Hose, failed to adequately train him in how to handle those concerns.

"Do you feel that St. Moritz in any way helped you deal with these problems that you were having with Ms. Kach?" he was asked during a deposition.

"No," Mr. Hose responded.

Later, he told attorneys that he spoke to Ms. Kach about two local murder investigations, "to show her that there's somebody bad out there that could hurt her," he said.

But it wasn't to threaten her, he continued.

"I loved that girl. I would never have done anything to hurt her, and I didn't," he said.
