Gov. Bruce Rauner has rejected posthumous clemency for an Illinois man despite the confession of a serial killer to the crime more than a decade after the inmate died.

Grover Thompson died in 1996 while serving a 40-year sentence for the attempted 1981 murder of 72-year-old Ida White in Mount Vernon.

Two police detectives told The Associated Press that serial killer Timothy Krajcir (CRY-chur) confessed to White's stabbing long after Thompson had died.

Krajcir is imprisoned for two southern Illinois killings, has received life sentences for five southeast Missouri killings and has pleaded guilty to killings in Kentucky and Pennsylvania.

A Dec. 2 Illinois Prisoner Review Board letter provided to The Associated Press shows that Rauner denied clemency for Thompson in late November. Rauner's office declined further comment.
