CARBONDALE, Ill. (WJPF) – Four Illinois men are facing federal charges in what prosecutors are calling a major mail theft and bank fraud scheme carried out in Carbondale.

Isaiah Jordan of Urbana, Demarius Flakes of Blue Island, Brian Nevils of South Holland, and Quentin Abrams of Charleston are all accused of using a stolen master key to access mail collection boxes throughout Carbondale. They stole and altered checks and then deposited the checks into bank accounts of accomplices, before ultimately transferring the money into their own accounts or accounts of associates.

Prosecutors say the men stole over 100 checks, totaling over $400,000.

Jordan, Nevils and Abrams are in custody, but Demarius Flakes is still at large. Anyone with information about his whereabouts are encouraged to contact law enforcement.
