Any new theories regarding new documents/witness testimony?

I had initially believed Kaylee and Maddie were sleeping together, but in light of new witness testimony by DM, it seems it’s very possible Kaylee was up and fled to Maddie’s room (would explain Murphy being out, the TV in her bedroom on, DM hearing her say “someone’s here”). Would anyone like to lay out their evolved theories/timeline? I’d be very interested to hear.
