Illinois Gov. Bruce Rauner signed legislation Tuesday meant to reduce gun trafficking by imposing stiffer penalties for the offense.
Those caught bringing guns into Illinois illegally will now face a prison sentence of four to 20 years for the first offense and up to 30 years for repeat offenders.
Over half of the guns found at crime scenes in Illinois reportedly come from out of state. Authorities say the guns are commonly purchased in places with looser gun laws. In Chicago, 60 percent of the recovered guns come from outside Illinois.
Illinois House Minority Leader Jim Durkin (R-Western Springs) sponsored the bill.
"There's never been a major focus on who arms the shooter," Durkin said, adding that now "they're going to be held accountable and they're going to be sentenced in a very strong fashion."
Chicago Mayor Rahm Emanuel described the measure as "a step in the right direction."
