yeah, but serial killers are not taking on a victim twice their size. They can pick their victims and pick the ones they are prepared for because of their vulnerability.
The other problem is the messy crime scene. It looks disorganized and unplanned.
I could see stabbing him as part of her plan to make him pay, but not unless he was disabled firsl. Would you plan a murder of someone twice your size with a knife? The Jury's going to talk about stuff like this.
I don't think this murder went as planned. The gun jammed.
IMO
I'd have to go through and dig up some serial killer cases to prove that there have been serial killers who have taken on victims bigger than they are. But I don't think size matters. strength, stamina and endurance matter. I've seen some guys who "look fit" but don't have the traits I just named.
I started working at a CrossFit gym. They have women Jodi's shape in there, beating some of the men, so I can't say Jodi's a wilting flower.
I keep explaining that I think she disabled Travis with duct tape. Again, she uses the "rope" to explain why a knife would be upstairs. Why can't the knife be up there to cut the duct tape to bind him instead? I think she was clever to come up with the rope story to cover for the duct tape. We see no evidence of a rope, but evidence of duct tape.
I agree that the murder did not go as planned. She'd hoped to duct tape him, taunt him in the shower, and shoot him. But she messed up when she bent over him to cut the duct tape roll off his hands with the knife. Or he charged her, knocked the gun away and she had to get the knife that she'd brought up there to cut the duct tape with.
I realize that they have not discussed that duct tape in court, but it was there, and it would be an explanation as to how she could overpower Travis with few defensive wounds.
There are tons of messy, gruesome crime scenes. The sloppiness of it should not be indicative of whether it was planned, though. It'd be a mistake for a jury to assume a disorganized sociopath would have a neat clean crime scene. Look at where Jodi lived. Her grandparents house was totally disorganized.
