We had yet to hear of a motive in the Tarwacki murders until today.
It was a brutal slaying that killed a Niles Township couple three and half years ago.
During opening statements today, the prosecution from state attorney general's office provided an outline of what to expect in the next two weeks when nearly 50 people will testify.
John Tarwacki, 42, was shot to death then stabbed.
His wife Carolyn, 39, was also shot but died after several stab wounds and was then beaten.
The case was cold for two years, with no DNA or fingerprints but there were footprints in the snow tracking Lintz allegedly from the crime scene to a place where he was staying in the neighborhood.
The prosecution argued it was a robbery gone wrong.
Doug Baker, a special assistant prosecutor from the state attorney general’s office said in his opening statement. “But out all of this there was one person that admitted to doing these crimes, who admitted doing it time and again, who in fact couldn't keep his mouth shut about it and that's the defendant Keith Lintz.
While the defense says there is no connection between the victims and the Lintz.
Lintz’s defense attorney, Greg Feldman said in his opening argument, “You are going to hear a lot of circumstantial evidence and however long this case is, I think you will find it lacking.”
John Tarwacki Sr. was the first witness to take the stand.
He recalled the morning he found his son and daughter-in-law dead in their home.
If found guilty Lintz faces life in prison without parole.
