WASHINGTON PARK, Ill. (KMOV)-- A man charged in the 2010 murder of Washington Park Mayor John Thornton will spend the next three decades in prison, officials announced Monday.
Aaron Jackson, 36, was sentenced Monday to 35 years in prison. The punishment starts immediately.
Jackson was arrested at the Relax Inn in Alorton on May 5, 2010. The month before, Jackson was charged with first-degree murder.
Prosecutors contended Jackson shot Thornton several times in the chest as the 52-year-old sat in his car on April 1, 2010. They theorized Thornton was headed home from his sanitary district job when Jackson flagged him down to ask for money.
Jackson was convicted in a second trial. A judge last October declared a mistrial after a witness changed her testimony about whether she talked to an investigator at the scene of the killing. That witness also claimed the investigator offered her a bribe.
Illinois State Police told News 4 a tip lead them to Jackson.
Jackson was initially questioned as a person of interest in the murder but investigators didn’t have enough information to charge him.
