For reference his real first name was Brett. It turns out he was killed by a teen girl with a serial killer obsession and a simp she roped into helping her. He also wasn't their intended victim. They originally planned to kill someone else and that fell through for whatever reason.

When he was killed, it was immediately framed as a 'hate crime' against the troons, without any evidence

Right. The police didn't investigate it as a hate crime until the troon activists threw a shit fit.
