Who Killed Laura Palmer?

Went to a Twin Peaks inspired art show at Clifton's downtown.  I felt like I was in a David Lynch dimension because they played music from all his movies, served cherry pie and coffee, there were red curtains everywhere, and the ambiance was just very Lynch-esque.  Was really hoping he would be there, so I could freak him out by saying something awkward and embarrassing, but alas, he was not.
