Former Deputy Pleads Guilty to Perjury
Michael Isenberg pleaded guilty to statutory sodomy 8 weeks ago, then he was convicted of perjury Monday afternoon in an unrelated case.
Cole County Prosecuting Attorney Bill Tackett said the former deputy's perjury case led people to question the local criminal justice system.
"In 17 years as a prosecutor, I've never seen anybody deliver as much pain and grief and anxiety as this guy did," said Tackett.
Isenberg lied under oath during a defendant's drug trial.
"I think it's the first perjury conviction in the law enforcement [community], certainly in this magnitude," added Tackett. "I mean, nobody could remember this ever happening. Old timers can't remember this ever happening."
Tackett said his office notified the court after discovering that Isenberg lied at Chism's trial. As a deputy, Isenberg played a role in 140 cases which Tackett's office had to review. The court set aside the judgment in 40 of those cases and released 18 people who had been convicted.
"We put people on the stand, that's what we do, and we vouch for their credibility," Tackett explained. This guy perjured himself. There's nothing that can unravel the system quicker than this, and what he did was inexcusable."
Isenberg faces up to 5 years in prison for sodomy, but the judge suspended imposition of sentence and put Isenberg on five years probation for the perjury charge. He also will have to register as a sex offender.
