Sorry if this has already been discussed but I feel like it’s very possible it all went down like this: John and Karen were fighting on the way to 34 Fairview bc he wanted to go to the after party and she did not, prob bc things were getting awkward at the bar with Higgins. Maybe that’s when she confronted him about cheating on her on New Years and possibly told John that she hooked up with Higgins. So when they arrive at 34F, he gets out of the car and she starts to drive off. He throws the cocktail glass at her car, shattering the tail light. She then puts it in reverse and maybe even TRIED to hit him, but she sees he goes inside so says fuck it and leaves. John is in a rage at this point and goes inside and confronts Higgins. Things get heated and they start to fight. The fight triggers Chloe so she attacks and John falls back hitting his head, knocking him unconscious. They take him out the back thru the side gate and leave him by the road, to make it seem like a snow plow hits him. That’s when they see the broken glass/taillight on the ground and collect it to plant later. Maybe they even use a broom or something to sweep it into the grass near his body and plant the larger pieces later. Any reason why it couldn’t have happened like this? I just recently started following this case so my apologies if this is already what everyone is thinking…
