Does Illinois do lethal injection?

Since 2011, the death penalty has been abolished in the United States state of Illinois.
Until 1928, the state of Illinois used hanging as a method of execution.

The state of Illinois adopted lethal injection as the default method of execution on September 8, 1983, but the electric chair remained operational to replace lethal injection if necessary.

Since 1977, the state of Illinois has executed a total of twelve people convicted of murder. All were put to death by lethal injection.

In 1999, Ripper Crew member Andrew Kokoraleis was executed in Illinois. Alton Coleman, another man sentenced in Illinois, was executed in Ohio.

On January 11, 2003, Republican Governor George Ryan commuted the sentences of all 167 inmates sentenced to death and pardoned four of them, a gesture that his opponents attribute to his ineligibility due to his unpopularity and charges of conspiracy, racketeering, and fraud.

On March 9, 2011, Democratic Governor Pat Quinn signed legislation to abolish the death penalty in Illinois, effective July 1, 2011, and commuted the death sentences of the fifteen inmates on Illinois’ death row to life imprisonment.
