It is the prosecutor's office that is the target of a new lawsuit as one father of a victim is fighting to get information.
Barry King wants answers. He's been waiting since 1977 to find out who killed his son Timothy, one of four children abducted and murdered by the Oakland County child killer.
"I never even asked - i just trusted the cops for 30 years," King said. "I have not seen one iota of evidence exonerating (Christopher) Busch or his companions."
King referring to Christopher Busch - a convicted child molester and the son of a high-powered auto executive who committed suicide shortly after the murders.
King has spent years fighting for access to police records - but he says he's still not getting the answers he wants from the Oakland County prosecutor.
"I didn't get anything from the prosecutor - zip, nada, zero," King said.
But prosecutor Jessica Cooper says her office has met with King as have numerous investigators.
King has filed two Freedom of Information Act lawsuits against the prosecutor and is taking his case to court once again.
"I would just like clarification from the prosecutor's office as to whether I'm being mistreated or not," he said.
King had a hearing scheduled for Wednesday but Cooper tells FOX 2 the hearing has been postponed.
Cooper says this is the same lawsuit King has filed in the past.
The Court of Appeals has already spoken in a published opinion, and the prosecutor is asking that his latest filing be dismissed.
Michigan State Police are still investigating this, anyone with any information is asked to call the tip line at (877) 616-4677.
