Joseph Chill (Earth-5192)

"Your Honor... not a day goes by that I don't wish I could take back what I did. Sure, I was desperate, like a lot of people back then... but that don't change what I did."

- - Joe Chill

Joseph "Joe" Chill was a street criminal operating in Gotham City who was the responsible for the deaths of Thomas and Martha Wayne in front of their son, Bruce, when he was a child, in an attempt to steal the family's money and Martha's jewelry in the place that became known as Crime Alley. The event led Bruce to develop post-traumatic stress disorder, and in years, become the vigilante Batman.

Murder of Thomas and Martha Wayne
Joe Chill was a resident of Gotham City during the city's famine and economic bankrupcy period. This drove him to a life of crime. He went to the Crime Alley, behind the Monarch Theatre, and cornered Thomas, Martha and Bruce Wayne. He demanded for Martha's pearls, but Thomas went to defend her, causing a panicked Chill to shoot them both dead at the front of the young Bruce.

After this, Chill was arrested by the GCPD and was impassioned at the Blackgate Penitentiary. There, Chill shared his cell with the mob boss Carmine Falcone, who became a confidant of his.
