FRANKLIN, Ind. -- The Johnson County prosecutor has subpoenaed the father of a missing Greenwood teen in an attempt to make him answer investigators' questions.

But Scott Louks' attorney said Thursday that Louks will not cooperate, alleging that police are inquiring about things that have nothing to do with the teen's disappearance.

Louks (pictured, left), who police say is not a suspect, is scheduled to meet Friday with investigators.

"I don't allow my clients to be strong-armed by the prosecutor's office," said Steve Litz, Louks' attorney.

Brookley Louks (pictured, right), 19, was reported missing June 24. Police found her car in a restaurant parking lot in Waverly a few days afterward.

Police have identified Joseph Nowicki, 53, of Greenwood, as a suspect. Nowicki, an acquaintance of the Louks family, has not been charged in her disappearance, but he is jailed on a weapons charge.

Greenwood police complained to the prosecutor's office that Scott Louks wasn't answering questions about Brookley's disappearance. Prosecutor Lance Hamner said Scott Louks must talk.

"They just need to know some timelines and who was where, when," Hamner said. "To not want to help find your daughter strikes everybody as strange."

Litz said his client cooperated with investigators at first, but then he became uncomfortable with the questioning.

"They started asking him all sorts of questions about his past and things that had nothing to do with Brookley's disappearance," Litz said.

Hamner said because Scott Louks isn't a suspect, he can't legally refuse to talk.

"You have a right to remain silent to keep from incriminating yourself, but you definitely don't have a right to remain silent to keep from incriminating someone else," Hamner said.
