Yes it is new info (to me at least) that 2/3 of the unknown male DNA samples were from blood.Is this actually new info? I feel like we learned this long ago, but my brain is leaking across different forums and it’s possible I’m confusing one tragedy with another.
What I THINK I recall immediately after the murders is all the talk of its being a party house, with innumerable people coming and going. I also THINK I recall that most of the guests had been tested for DNA.
Even if I’m mixed up about this, yes unknown bloody male DNA seems startling at first glance. However, blood could come from anything at a party house, and to me the integral puzzle piece is WHERE Bryan’s DNA was found.
You’d really have to go out of your way, if you’re innocent, to get your DNA on the sheath snap of the murder weapon found tucked underneath one of the victims.
Also this would suggest two murderers, I suppose, and DM only saw and heard one man.
IMO
ETA: @Boxer I just saw your post after I posted…agree with you.
I don't discount the sheath DNA, and agree that is the main one. I am just shocked that unknown blood samples at the scene weren't more thoroughly investigated.
