I genuinely hope McCraney gets a fair trial, as would most. The majority of people around here believe he is innocent, even with the DNA evidence presented. For alot of them, that sentiment is based of the preconceived belief of the high level of corruption that has always been associated with OPD. Of course with social media and 24/7 new sources, police in general, all are painted with that generalization. But I digress.
So obviously the DNA report is a big game changer. But here are some interesting caveats to ponder in relation to the DNA.
Semen was found on the sweater, underwear, and within the vaginal cavity. Which as the lawyer states only implies he potentially knew them, interacted with at least Beasley. Semen can be viable for up to 7 days I believe in the vaginal cavity (dependent on age of female, pH, etc), around the same time on clothes. Mind you, washing clothes doesn't necessarily rid them of stains AND can potentially spread to other articles that may be washed.
That means if the laboratory findings are correct, pointing to McCraney, then there is potential that they have met from the time of the prior weekend to the night of the murders. Figuring out what Beasley did in the afternoon/nights of the week would be insightful, school records of missing class or anything too. I'm inclined that any sexual encounter would be consensual unless it was a forced interaction say in a house at gun point.
Now, one must consider the sample collected from Beasley. How well preserved was the samples? So many variables that would compromise the stains/samples from the collection of them, handling of the bodies on scene, environmental factors. Assuming they were murdered between 12p-2am plus the 6 hours stuck in a fairly humid trunk, also the environment where the murders were committed all could skew the sample. Same goes for the sample the collected from McCraney. His would exclude the environmental factors aside from the room it was collected so it would be more with the person that collected, handled, packaged, and shipped it. Of course, human error in the lab can be prevalent. So in reality, even with the family tree created, matching the DNA, its still not 100% (its extremely strong, dont get me wrong) because even with the profile of the sample be it degraded, partial, whatever, I don't like that they base the claims on the probability of the match.
Hope this makes some sense, sometimes its difficult for me to adequately articulate all things medical lol.
I am going to type out my opinion on what could have happened, potentially tying in the McCraney DNA and his relationship with Beasley. This will be based on the what has been officially publicized. With that being, please correct me with anything I dont state being correct as for as the timeline and such that is deemed common knowledge
