State police served Anthony "Bindy" Rock, 68, with his papers Friday (the 15th), a source said. Contacted Friday night, Rock declined to comment.
Rock was a central figure in an unsanctioned undercover investigation Peterson undertook while he was on loan from the Bolingbrook Police Department to the Metropolitan Area Narcotics Squad in 1985. That investigation led to Peterson's indictment on charges of official misconduct and failure to report a bribe.
Peterson was fired following his indictment when the Bolingbrook Police and Fire Commission found him guilty of those charges, as well as disobedience and conducting a self-assigned investigation.
On different occasions, two appellate court judges ruled Peterson's firing was excessive. The criminal charges against him were dropped and he got his job back.
Peterson's trouble from two decades ago started when he revealed to his supervisors that he'd embarked on a solo narcotics investigation of Rock. A state police undercover officer was already working on Rock, according to court documents, but Peterson went ahead with his probe and failed to tell his superiors until it hit a dead end.
"You had better take your guns off. I have something to say that's real bad," Peterson allegedly told his supervisors at the time.
And Peterson's former supervisor with the narcotics squad, retired state police Lt. Col. Ronald Janota accused Peterson of leaking the state agent's identity to Rock.
Before he was investigated by Peterson, Rock was convicted of the April 1970 murder of Joliet police Det. William Loscheider. But it was actually a fellow officer who gunned down Loscheider during a burglary investigation at a North Broadway liquor warehouse, but courts blamed Rock because the death occurred while Rock was committing a crime. Rock, a reputed loan shark, was allegedly fleeing the scene with two accomplices when Loscheider was killed by friendly fire.
The spokesman for the state's attorney's office, Charles B. Pelkie, said he could not comment on why or even if Rock was subpoenaed. Peterson himself could not understand what prosecutors wanted with Rock, who he had arrested once before the unauthorized investigation in 1985.
"All he knows is, I tried to buy dope from him a couple times. I put him away for 20 years," Peterson said. "He got out on appeal."
Peterson's fourth wife, Stacy Peterson, has been missing since Oct. 28.
