Okay, this is more of a head-scratcher than it first appears.
Because at first, it seems like an open-and-shut case - she drove her drunk-drove her drunk cop boyfriend to his friend's house and backed over him and killed him, either accidentally or on purpose, and in the morning she noticed her taillight was busted out.
When he didn't come home, she called everyone trying to find him, searching for him in the snow until they found him, and then said "Oh my God, I didn't kill him, did I? I killed him?"
Also, she left horrible, verbally abusive voicemails for him previously, and admits they were arguing and she was angry when she dropped him off at his friends' house (who didn't like her).
Now, Occam's razor would say the simplest explanation is answer the best - she killed him.
However, Occam's razor isn't always right, some things aren't as simple as they first appear - plus you still needs facts and evidence.
Because remember, we once believed the sun traveled across the sky over our flat earth because it "looked that way."
There was a dog that was known to be aggressive in his friend's house, but inside due to the blizzard. O'Keefe's cop friends said he never actually made it into the house - but the body had dog bite marks on it.
The bite marks were tested for DNA and came back positive for animal bites; however, they can't test the his cop friend's dog because they "sent it away because it was too aggressive," but no one can find where they sent it.
There is security video evidence of her coming home after dropping him off about 3 a.m. and the taillight appears to be intact at that time.
The evidence collection at the scene was botched horribly, collected in red Solo cups and plastic shopping bags by the cop friends themselves, and most importantly, the red tail light fragments supposedly found near the body weren't covered with snow, like the actual body was, thought it was a blizzard.
There had been a a previous coverup in that same town police department over a cop strangling to death his teenage girlfriend.
Anyone that has publicly written or spoken about the Canton police department finds dead animals in their yard or hanging on ropes on their porches.
Two of the cops at the house that night have been suspended for not disclosing evidence about their cop friend who had killed his girlfriend, as well as inappropriately harassing their critics.
Lastly and most importantly - the defense hanging their argument almost entirely on this piece of evidence - Jennifer McCabe, girlfriend to one of the cops at the house that night, "How long does it take a body to die in the cold" at 2:27 a.m." - about an hour after O'Keefe was dropped off - and 4 hours before his body was found.
So the defense's theory is that Keefe actually did make it in the house, the dog attacked him, he fought the dog, his cop friend owner that owned the dog and he physically fought and O'Keefe went down hard, busted his head on the floor, and died accidentally, and the police are covering it up.
So let's go with Occam's razor and say Karen is guilty, whether she did it on purpose or not - but we still have these questions:
Where did those dog bites come from, considering the dog was inside during blizzard conditions, and where is the dog now?
Why weren't the shards of taillight covered in snow, like the body?
Why was her taillight not busted at 3 a.m. on security camera but was busted by 6:30 a.m.?
Why was anyone at the friend's house searching for how long it takes for someone to die in the cold at 2:27 a.m. - 4 hours before his body was found?
In watching her interviews, even if Karen IS guilty, I believe she believes herself that she's not - but that wouldn't be uncommon. Some people can't come to terms later with what they've done, plus she was drunk.
The saddest thing about this whole story is the O'Keefe's adopted children, who lost both parents to cancer (their mother was O'Keefe's sister) and O'Keefe is now dead - so these children have lost everyone they've ever known as a parent 😢
So I don't know, though it's most likely she's guilty, I will admit those are odd things that do leave doubt, so I will officially say I have no opinion.
What I DO know for sure is that - I would never hang out with any of those people on either side ever!
Bar-hopping cops during blizzards who drive home drunk?
One of those cops being O'Keefe, who is partying instead of being home with his adopted kids during a blizzard?"
Girlfriends that scream "I hate you" on repeat voicemails that drive drunk during blizzards and drop off their drunk boyfriend's and don't wait for him to make it to the door?
However, this case has been an interesting case study of people going with what they choose to believe rather than the facts, which is rampant nowadays because people don't seem to know the difference.
The only thing I know for sure is that I wouldn't ever want to know or hang out with any of those people, and further, Not only would I never want to hang out with any of these people, but remind me never to go to Canton, Massachusetts!
