[[Free fall calculator....if saget was 6 ft tall...his head would be 6 ft up...falling limp, straight on his head would be at about 12 mph..]]
Even faster if falling down a set of stairs- depending on how many stairs, coulda hit a couple of times- IF stairs were involved-
Either way...original story was that he simply bumped his head...and decided to go to bed...so story doesn’t match physical evidence...hence, my armchair sleuthing comes out...
