Michael Jerome Corbitt (March 17, 1944 - July 27, 2004) was a police chief of Willow Springs, Illinois, and an associate of Chicago Outfit mobsters such as Sal Bastone, Sam "Momo" Giancana and Antonino "Tony," "Joe Batters" Accardo. He became a cooperating witness after being convicted of aiding in the murder of Chicagoan Diane Masters, by her husband, Alan. Corbitt has authored a book about his experiences entitled, "The Cop Who Was a Mobster.
Michael Corbitt was born to an Irish American family in Chicago, Illinois. After a several years in a Roman Catholic parochial school, he was transferred to public school at age 9. He would later recall that, without a Catholic school uniform to hide behind, it was obvious just how poor his family was. Humiliated by the poverty of his parents and tired of hand-me-down toys and clothing, he turned to shoplifting and later graduated to running with an Italian-American street gang.
In always hanging around where Corbitt could be seen by Mob members, he soon drew the attention of the Chicago Outfit, who recruited him into running errands around one of its social clubs.
