The robber’s threatening note made a Chicago bank job easy to solve: The FBI says the suspect wrote it on his pay stub.
An FBI affidavit says the man walked into a Fifth Third Bank on Friday and handed a teller a note that read “Be Quick Be Quit (sic). Give your cash or I’ll shoot.” The robber got about $400 but left half of his note.
Investigators found the other half outside the bank’s front doors.
Authorities say that part of the man’s October pay stub had his name and address.
