Was the DNA found under his nails ever retested?
In my personal opinion based on the documents provided the “PERSONAL GRUDGE” would make me think it was a close person to Kirk meaning a “Friend”. he was a stay in person I believe Kirk Called some friends over because he was home alone then went out to get take out and when they came back to Kirk’s house among the friends 1 had a personal grudge against Kirk and was the person who murdered Kirk. The friends of Kirk should be tested.
Don’t forget, you don’t want to throw theories out there and then hope that investigations happen to to prove or disprove the theory. Professional investigations follow the fact patterns instead of trying to get a theory to “stick”.
Should friends be talked to and people close to him interviewed of course! That’s basic victimology done in a procedural way.
We see this happen time and time again. “It has to be the husband”, “it has to be the parents”. Those might end up being true but you don’t jump to conclusions and then investigate out of them. You investigate at the start to get to the conclusion…WHATEVER the facts may be to keep an open mind for professional investigations 🕵🏻♂️
Definitely would say that the DNA under his nails should be tested again especially since he had defensive wounds, have to believe he got some of his attackers DNA fighting them off. I would argue differently if a gun had been used because it puts distance between the victim and suspect but seeing as a knife was used that leaves little to no space for the victim not to be able to collect some form of DNA and again he did have defensive wounds. I’m not going to hop on the theory that it was a friend even though the crime does suggest it was a personal attack, but the friends acting weirdly around family after the crime can be completely normal because no everyone knows what to say or do towards family members after losing someone. Especially if those friends were questioned by law enforcement, it could add to the awkwardness because now they feel the family has already made it up in their minds that they’re the suspect. I also won’t completely rule them out because of the fight between the friends over the girl and the fact his grandmother wanted him to go live with his aunt till everything cooled down suggest the argument could of been a little more than just words thrown back and forth between friends.
