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 Laurence's work and threw him into Arkham City as a Political Prisoner. Eventually, Laurence became privy to an attempt on his life, and eventually called for help from the old FM Tower. Batman eventually picked up the SOS signal, found Laurence nearby, and he explained 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 to Wonder Tower, Laurence was killed via a sniper round, and Batman had deduced Deadshot's involvement shortly thereafter.
- Laurence was not actually named when Batman spoke to him. He was instead named in the contract list schedule that was found on Deadshot's PDA.
