South Holland police said the suspect, Joseph Wingard, turned himself in to police at 8 p.m. Saturday.
He has been charged with first degree murder for the June death of his wife, Lone Williams, police said.
Wingard, 49, was recently released from prison after he was convicted of killing two women in Calumet City in 1991, when he was 17.
The family of Williams had previously offered a reward to find Wingard when he was on the run.
