Bryan Murphy was an Account Manager at the Gotham Merchant's Bank and murder victim.
Batman: Arkham Origins
Prior to Christmas Eve, Bryan Murphy was convinced by the con artist Robert Hanes into pulling an insurance scam against the Gotham Merchant's Bank in exchange for a cut of the fee. Murphy began getting second thoughts and planned to expose the scam to either the GCPD or his bosses at the Gotham Merchant's Bank. Unfortunately for him, Hanes anticipated that crisis in conscience and silenced Murphy by pushing him over a broken railing into Jezebel Plaza. He died instantly from internal injuries. Batman heard of the fall via a police scanner, solved the murder, found Hanes, and apprehended him.
