A private investigator thinks he knows who killed a Paris couple in 1986.
Bill Clutter sent an affidavit to Gov. Pat Quinn, encouraging him to sign a clemency petition for Herb Whitlock and Randy Steidl.
Whitlock and Steidl were originally convicted of the murders and spent nearly two decades behind bars. In the 14 page document, Clutter lays out evidence that he says shows that Texas death row inmate Tommy Lynn Sells was the one killed Dyke and Karen Rhoades and then set the house on fire.
Clutter says Sells was a drifter who checked into a nearby hotel just hours before the murders. He also wrote Clutter a letter, where he appeared to know more about the murders than he let on.
