Is it true or false that Jason Herbert (aka Jason John) died? (a member of Big Fun pop group)

Is it true or false that Jason Herbert (aka Jason John) died? You can read about it here and here. But I don't know if it's true or false. Please, write a comment if you know something about it. Thank you. Here the wikipedia about him and we think it's true because the Wikipedia reports January 2019 as the year of death.
