The former 90 Day Fiance star has passed away due to Covid-19 complications and possibly other factors, according to his sister Shannon.
She told TMZ that her brother died in a Florida hospital after being admitted to ICU, and his family was able tobe with him during his final moments and held his hand as he passed on.
Shannon also told the website that Jason - who appeared on the reality show's second series in 2014 - wasn't vaccinated and didn't have any pre-existing medical conditions to the family's knowledge.
But they later went their separate ways in 2017 and filed for divorce in January 2018.

Speaking about their separation, Jason previously said: "A successful relationship is communication, physical attraction and doing whatever it takes.
"Right now it's time to go in different directions. I think we'll remain friends. She knows I have her best interests at heart.
"She did not come here just to become an American citizen. She had a good life in Brazil. She was about to finish college. She didn't have to marry me."
He also admitted there would be "no fighting" between the pair as they went their separate ways.
