JOLIET, Ill. (CBS) — A Frankfort man who was already behind bars for murder has been charged with trying to hire someone to help him kill a Will County prosecutor.

Brian Trainauskas, 36, was charged with solicitation of murder on Tuesday, authorities said. His case has been referred to the Illinois Attorney General’s office.

Trainauskas was already in jail, charged with killing Monica Timar of Frankfort Township in January 2009. Timar’s body was found wrapped in a bed comforter in the trunk of her 2007 Ford Mustang.

Trainauskas told police he found Timar’s body on his bathroom floor, where she had shot herself with his shotgun. But he was arrested after police determined Timar could not have shot herself with the gun.

Charles Pelkie, spokesman for the Will County State’s Attorney’s office, declined to comment on the new case other than to say it’s important to make sure prosecutors are safe and able to perform their duties.

“We’re very concerned that one of our prosecutors might have been targeted in such a manner,” Pelkie said.
