A woman who ran away as a teenager and lived with a school security guard for a decade filed a federal lawsuit Thursday against him, the city, the school district and others, claiming he assaulted her and that they failed to prevent or properly investigate her disappearance.

Tanya Nicole Kach, 24, came forward March 21 and told police she ran away and had been living in Thomas Hose's house in a Pittsburgh suburb for 10 years. Kach told police that Hose, 48, kept her in a bedroom in the small, two-story home where he lived with his parents.

The lawsuit, filed in U.S. District Court in Pittsburgh, claims police and city officials involved in the case were incompetent. It also alleges school officials knew or should have known Kach and Hose were having an improper relationship before her disappearance and did nothing to stop it.

"Now she has a completely stilted existence. She suffers from post traumatic stress disorder. She's unable to function in the community," said Lawrence Fisher, Kach's attorney. "We're calling on those institutions that failed her 10 years ago to step up and do something to help her."

Hose has pleaded not guilty to statutory sexual assault, three counts of involuntary deviate sexual intercourse, two counts of indecent assault and other charges. He is living under house arrest and unemployed, his attorney said.
