Jon Schnepp, known for his animation work on shows like Metalocalypse and The Venture Bros., has died at 51. Schnepp passed away on July 19 after suffering a massive stroke last week. The news was confirmed by his fiance, Holly Payne, in a statement, which she released on Twitter. Here's what Payne had to say.

"It is with a broken heart that I announce the passing of our beloved Jon Schnepp, who died peacefully on July 19, 2018. Jon ultimately succumbed to the effects of a massive stroke. He had a blood clot removed from his left carotid artery, but the bleeding could not be stopped. Irreparable and catastrophic damage was caused to both hemispheres and all brain activity ceased. His sister Deborah and I had to make the difficult decision to take him off of life support. There was no possible way for him to recover. Please understand."

Born on May 16, 1967, Jon Schnepp managed to break into the world of animation in the late 1990s, with his first credit coming on Nickelodeon's KaBlam! in 1998. Schnepp would later go on to become a fixture on Cartoon Network's Adult Swim lineup behind the scenes as the chief creative force behind Metalocalypse, which debuted in 2006 and ran through 2012. Schnepp also worked on shows like The Venture Bros., Space Ghost Coast to Coast and Aqua Teen Hunger Force. Holly Payne also detailed some of Schnepp's last moments, which he spent surrounded by loved ones.

"I spent the last hour of his life with him holding him, laying my head across his massive chest, kissing him, stroking his hair, playing his favorite songs, and telling him over and over again how much I love him. My life has been forever changed by Jon. I feel endlessly grateful to have shared 16 years of laughter, love and incredible adventures together, including the making of a feature film, as well as a television series that I hope to complete and release later this year in his honor. Jon's mother Miriam, his father David, his sister Deborah and I are devastated beyond measure. We appreciate your love and support, and most importantly your understanding of our privacy at this time as we grieve."

In the movie world, Jon Schnepp was known for directing the 2015 documentary The Death of Superman Lives: What Happened? The movie details the Tim Burton Superman movie starring Nicolas Cage that was developed by Warner Bros. in the 90s but never actually got made. Schnepp also directed a segment for the 2012 horror anthology movie The ABCs of Death titled W is for WTF?

There has been an outpouring of support on social media following his passing. Patton Oswalt took to Twitter saying, "Jon Schnepp, a truly creative and good-hearted man, has passed away. If you can, please help Holly with the massive, life-crushing medical bills? Let's help someone who's been devastated." Holly Payne created a GoFundMe page to help cover the mounting medical expenses that came as a result of her late fiance's hospitalization.
