Getting back into it — pls help catch me up

I’m just now learning of the people who presume BK to be innocent.. Those of you that do, please link or comment your most compelling reasons, videos, docs, etc. so that I can catch up! The last I read of this case I felt as though BK was the only suspect, but after spending the last half hour or so on the sub, I’m really interested in see differing viewpoints.
