I would imagine that it either started in the kitchen or tumbled into there, and perhaps she was attempting to defend herself with the only thing she could grasp, a fork. Perhaps he took it from her and stabbed her with it? No matter how much he attempted to plan it, clearly things went sideways and they were both grasping at whatever they could, her to save her life and him to end it. What a monster she must have been so scared.
I've thought about a struggle. It could not have been much of a battle if Mom and other siblings were home "sleeping" at the time, and didn't wake up. Hmmm. Also, yes the suicide note is definitely mentioned to justify the 1st degree Homicide charge. Other strange things not yet figured out..
Key found outside
Copper ligature found in back yard
Him seen driving his Dodge Charger in surveillance..but blood found in Mom's car
Lelevier "attack" a week after the Homicide
He had a Den? did he sleep in Den?
Mother is about to give birth to their child, we're they estranged in some way?
