JOLIET – Will County State’s Attorney James Glasgow announces that a Bolingbrook man faces up to 15 years in prison after being convicted this week of his fifth DUI.


A jury deliberated for 90 minutes Wednesday before finding John A. Prepura, 52, of the 100 block of North Canyon Drive, guilty of aggravated driving under the influence of alcohol, a Class 1 felony that carries a penalty of 4-15 years in prison. Under Illinois law, Prepura cannot receive a sentence of probation. He has four prior DUI violations dating back to 1980 in both Cook and Will Counties.


Circuit Judge Carla Alessio Policandriotes ordered the defendant taken into custody pending his sentencing, which is scheduled for November 30.


Prepura was pulled over by off-duty Cook County Sheriff’s Department Deputy Primitivo Olavarria, who witnessed the car weaving dangerously and driving on the shoulder of Interstate 55 near Bolingbrook at about 11 p.m. on March 28, 2009.


Deputy Olavarria, who was driving his personal vehicle, followed Prepura until the defendant stopped safely at a traffic signal on Illinois 53. He pulled up behind Prepura, approached his vehicle and informed the man he appeared to be too intoxicated to drive and asked for his car keys. Prepura turned off his vehicle and surrendered his keys without incident. Olavarria then contacted Bolingbrook police who administered field sobriety tests and took Prepura into custody.


“Deputy Olavarria’s concern for the safety of everyone on the road that night is highly commendable. Even though he was off-duty, he utilized his police officer training to safely and effectively take a drunken driver off the streets before someone could be injured or killed,” State’s Attorney Glasgow said. “Deputy Olavarria is a credit to the Cook County Sheriff’s Department as well as to Sheriff Tom Dart.”


The state’s attorney also credited Assistant State’s Attorneys Matt Guzman and Chris Messina for their expert trial work that will take a drunken driver off the streets and place him behind bars.
