Chicago radio station WKSC-FM invited listeners to call in and confess any evil deeds they may have committed. A man who referred to himself as “D” called in and bragged that he and five accomplices had robbed a suburban TCF Bank.

He provided details of the unsolved crime, including that a bank employee had been involved, that they tied up the bank workers, and that they had made off with $81,000.

A bank employee driving into work was listening to WKSC and recognized the story as a holdup that had taken place at her bank in April 2004. She called the police.

The FBI traced the call back to a cell phone belonging to Randy Washington, 24, of Dolton.

FBI agents headed to the radio station, which turned over a cell phone number registered in Washington’s name, along with a transcript and recording of Washington’s call.

Washington appeared in federal court this week on charges that he and William Slate, 19, robbed the TCF Bank at 3220 S. Chicago Rd. in South Chicago Heights.

Washington was ordered detained. Slate, who recently moved to Dallas from Tinley Park, will be extradited to Chicago. Authorities are still looking for four others involved in the robbery.
