Wayne L. Field III was wearing Williams' clothing -- including fur -- and was peeking through the window of Williams' residence when an officer approached the townhome on Benton Place in November 2011, police said.
Field, 53, who was also wearing Williams' 2005 World Series ring, watch, shirt, jeans and sweatshirt, was arrested for the burglary, authorities said.
Judge Joseph G. Kazmierski Jr. previously ruled Field unfit for trial and found him not guilty by reason on insanity during a Friday discharge hearing, according to the Cook County State's Attorney's office.
Field has previously been arrested for assault, indecent exposure and sexual abuse, according to court records. He was also arrested for misdemeanor battery in early September 2011 and public indecency in July 2011, but those charges were dropped.
Field also was convicted of domestic battery in 2010.
In the early 1980s, he was ordered to undergo court supervision for misdemeanor criminal sexual abuse.
