Dude definitely had some issues. He always claimed that he was treated like a spare by the other kid actors because he was the only one who didn’t look like a model. That has the ring of truth to it.
Had an opportunity to meet him in Monroe, MI with my daughter when he was involved with a couple of charities. I believe it was shortly thereafter he was involved in some drug-related (I think) issues. At the time though, he seemed like a pretty decent guy who hadn’t let his fame go to his head.
Regardless, 44 is much too young for anyone to pass. Condolences to his family
