What if it was his father's DNA he submitted?
MOO
MOO- that would do him no good.
His fathers DNA (From family trash can) is what ultimately confirmed to the police that the distant relative match previously obtained by detectives connecting BK via sample left on the knife sheath was accurate.. now… with the fathers DNA from the trash to compare…they had a much closer match to the DNA sample left on the Knife Sheath A 99% first degree relative match… so really if you think about it that way… his fathers DNA is what got him arrested.. provided the strongest substantial, probable cause evidence to arrest him.
If he is trying to swap out his online national database DNA sample with anyone… He should have done a stranger… Not his father who leads straight back to him and defeats the purpose of submitting someone else’s DNA….
I know he is heartless if he can commit that Number of senseless murders in one night… but even if he swapped dads DNA for his.. Dad is married and lives across the country… dads dna sample would still ultimately lead investigators to son, once dads alibi clears.
im also not really sure how he could achieve acquiring a stranger sample /swab with his lack of charm and awkward nature…..which you need a mouth swab to submit the test… challenging to say the least for a non-healthcare provider… to request from strangers….possible yes… likely…no.
MOO- I just don’t understand….why someone who’s considering murdering someone/multiple people…someone who had been stalking people/was making plans in his head to commit a horrific crime, would submit his DNA in a national database for any reason…
He of all people had to have known the danger of this and how it could lead to his arrest if any mistake was made and left behind any forensic evidence.
if he did….that’s a big IF….the only logical thing i can think of is if he provided a fake name and age… fake email, fake place of birth… etc. to run the test…. And did it purely to find out if any of his other relatives matched with him…. To clarify to him and him alone….. whether or not LE could ever connect him to crimes via his DNA unintentionally left behind at a crime scene.
I feel like this is something he’d like to know and forget about the consequences of obtaining such knowledge while having tunnel vision on the planning of the crime he wanted to commit.
Still… no part of my theory explains why LE claims it was a distant relative only that matched with the DNA on the knife sheath. If indeed he did submit his DNA to a large company that LE uses to compare forensic evidence… LE Never mentions his DNA Coming up as a match. Which leads me to believe it was not there.
Which makes me wonder if he researched how to dilute a DNA sample to give only a partial match. (FYI… not sure this is even possible.. but if his goal was to locate relatives who may have submitted their DNA that may connect to him… not him wanting to know his ancestry… and him understanding the percentages of accuracy from different types of samples…and what percentage is needed to be fully genetically identified…It’s possible? Maybe?) At this point If this was his goal… finding partial matches to his diluted sample may have sufficed to him. The test would list partial/distant relative matches and give him the information he needed… potentially without fully connecting him / creating a full accurate genetic profile on him.
Tampering with the submission however…. Could have backfired on him… Maybe, just maybe… he was generated a limited genetic profile… had no hits on the relatives which all know where in there….
Which made him sigh in relief… when it was revealed no genetic matches appeared.
Which was only because he tampered too much with his sample.
again… all MOO - Just throwing out ideas. Trying to understand why a criminal / criminologist get submits his dna to ancestry dna right before he commits multiple murders. DOES NOT MAKE SENSE.
