During the set up for the mega-prison Arkham City, Lawrence Graham was ordered by Hugo Strange to work on Wonder Tower by implementing various wireless communication relay points. Six months later, Strange repaid his work by throwing him into Arkham City as a political prisoner. Eventually, he became privy to an attempt on his life, eventually calling for help from the old FM tower. Batman eventually picked up the SOS signal and found him nearby, with his explaining what happened that got him locked up and hunted down. However, just as he was about to give Batman the specifications of the signal relay points at Wonder Tower, he was killed via a sniper round, with Batman deducing Deadshot's involvement shortly thereafter.
- He is not actually named when Batman speaks with him. He is instead named in the contract list schedule included on Deadshot's PDA.
