Rest in peace. Steve Dillon, the renowned British comic book artist who created Preacher and cofounded Deadline magazine, died in NYC recently, his younger brother confirmed via Twitter on Saturday, October 22.

“Sad to confirm he death of Steve, my big brother and my hero,” Glyn Dillon tweeted Saturday morning. “He passed away in the city he loved (NYC). He will be sorely missed. Cheers x.”

Dillon, whose birthday is publicly listed as 1962, was either 53 or 54. His cause of death has not yet been released.

The comic book artist was perhaps best known for co-creating comic series Preacher, which influenced Stephen King’s own series, The Dark Tower: The Gunslinger Born (and was recently adapted into a TV show for AMC). He also co-created and edited Deadline magazine in 1988, which was published for seven years.

The self-proclaimed “comic book bloke” was in NYC for New York Comic Con, with his last tweet on October 7, announcing his whereabouts at the larger than life conference.

“Hi, NYCC people!” he wrote at the time. “My shift at the Hero Initiative booth today is changed. I’ll be there from around 2.30 till around 6. Cheers!”

The comics community has reacted swiftly to news of Dillon’s death, mourning a man many considered to be a prodigy. (His first professional work was published when he was just 16.)
