What happened to Mr. Turner on Boy Meets World?

“he’s never seen or anything again until the episode where they graduate from high school over a year later.”

So, what you’re saying here is that he was seen in this episode? If that’s the case, then it’s quite obvious he didn’t die (actually, he isn’t seen - only mentioned as being in the area, but not on screen). The truth is, this is one of those famous television plots that were never resolved. There was never an end to Mr. Turner’s story, but all we know is that he did survive.

A kid from the first season comes back on the show for the last few episodes when they’re in high school. When they ask where he’s been he points off camera and says over there…in a part of the school that’s never seen and supposedly no one ever comes back from…or so says Shawn and Cory. The kid laughs and says that’s silly and then says “Hey, Mr. Turner, wait up” and walks off screen. You never see Mr. Turner after the accident episode.

That’s what I said … in less words.
