Jon Schnepp's fiancee, Holly Payne, confirmed that the filmmaker died at age 51 on Thursday, one week after suffering a stoke. "It is with a broken heart the Schnepp family and I must announce the passing of our beloved Jon Schnepp, who died peacefully on July 19, 2018," Payne wrote on Twitter. "Jon ultimately succumbed to the effects of a massive stroke." She elaborated, "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."

Payne concluded by letting her followers know that she and Schnepp's family "appreciate your love and support, and, most importantly, your understanding of our privacy at this time as we grieve." Schnepp suffered the stroke on July 12, according to a statement released by Payne and his family last week. A GoFundMe page was created for Schnepp's medical bills, which has since raised more than $100,000 of its $150,000 goal.

"Jon is on life support at this time," wrote Payne. "While everyone is desperate for updates on his condition, we ask for your understanding on giving us the privacy we need over the next few days as we deal with the difficult decisions concerning Jon’s care." Schnepp was best known for his work on Adult Swim's Metalocalypse. He served as the writer and key director of the animated series, which aired for four seasons from 2006 until 2012. Not long after news of Schnepp's death broke, his good friend Patton Oswalt took to Twitter to pay tribute. "Jon Schnepp, a truly creative and good-hearted man, has passed away," the comedian tweeted, accompanied by a link to Payne's GoFundMe page. "If you can, please help Holly with the massive, life-crushing medical bills? Let's help someone who's been devastated."
