James “Jimmy I” Inendino has always been known as a devoted Outfit member and lately known as one of the top leaders of the Chicago Mob. Now, the I-Team is revealing what has been unknown to most.

Inendino is listed in FBI records obtained by the I-Team as Informant Number 6931-C. Documents show his FBI connection dates back in the late 1960s and mid-1970s. This information did not appear to be common knowledge all the way up to Inendino’s death of natural causes at age 80 this past week.
