Robert Hanes

Robert Hanes was a well-known con artist involved in various scams, as well as a murderer.

Batman: Arkham Origins
Robert Hanes was a con artist who specialized in various scams over a long period of time, usually with inside men involved that he paid a cut to when the scam was completed. At some point, he encountered an account manager at the Gotham Merchant's Bank, Bryan Murphy, and recruited him to his latest scam by convincing him to give him (and presumably the other scam artists involved in the scam) the account number and password for one of the Gotham Merchant Bank's clients. He also planned to print out fake IDs for various criminals who weren't native to Gotham, nor ever set foot into a bank, to ensure the scam went off without a hitch in case the bank got suspicious. By the time of Christmas Eve, however, Murphy had gained second thoughts on the scam and wanted out, presumably also threatening to expose the scam to either the GCPD or the bank employees. However, Hanes, anticipating this, silenced him by shoving him off the roof into Jezebel Plaza, breaking the railing in the process, as he was unable to afford letting the scam become public. Batman, having learned of the incident from a police scanner, arrived and deduced Hanes role in the murder from fingerprints on Murphy's suitcase (which has fallen onto a ledge between the railing and the plaza). Batman, due to Alfred narrowing down the search area for Batman ahead of time, managed to track down Hanes to a rooftop at the Diamond District, also overhearing he and his gang planning their scam. Batman then proceeded to subdue all of them, and interrogated Hanes on the murder and the scam, before leaving him to be apprehended by the GCPD.
