Lew Moxon was the crime boss who hired Joe Chill to kill Thomas and Martha Wayne.
History[]
He is dying of presumably natural causes and is visited by Batman, disguised as a clergyman, while in the hospital. Moxon admits to some of the things he has felt bad about over the course of his life. He also confesses that he had ordered the murder of Thomas and Martha Wayne, due to the fact that he had been thrown into Blackgate Penitentiary because of a past event involving the young doctor. Moxon regrets the murder of Martha Wayne, something that was not part of the original plan, saying he thought it was wrong to leave young Bruce without a mother. Batman demands the name of Moxon's hired killer several times, but Lew avoids the question. Finally, with his dying breath, he gasps out a single word "Chill". This results in Batman reopening the Wayne murder case.
