Illinois has not put a criminal to death since the 1999 execution of Andrew Kokoraleis. Then-Gov. George Ryan put the practice on hold after learning that more than a dozen death row prisoners were actually innocent according to NBC Chicago.
In 2011, then-Gov. Pat Quinn officially signed a bill repealing the death penalty.
Rauner's notion to bring back the death penalty was part of an amendatory veto of House Bill 1468, which would have implemented a 72-hour waiting period on the sale of assault weapons in Illinois. The veto expands that waiting period proposal to all gun sales in the state.
