Someone in one of our other threads had brought up if a vehicle was involved in the other attacks and where it might have been parked, or if the perp simply was on foot. The one was in a parking garage and he was on foot, but the vehicle could have been parked there, and the other of course included the victim being in the actual truck.
This is a really great point you bring up, Dad. Why is he attacking both on foot and with a car? Being on foot would lead me to believe he lives very close to these attacks. Maybe the car isn't used to get him to the campus, but just as a place to carry out the attacks.
Do you think he killed Brianna on the couch, in the car or at a property?
I think he drives to the area from somewhere 10-15 minutes away. If he gets out of the truck/SUV to troll for any period of time, then he is pretty bold.
It is stated that she died of strangulation. Others have pointed out that it take a few minutes to strangulate, with intoxication also being a factor.
Since there was Brianna's blood on the pillow, he either hit her immediately or subsequent to her resisting. In either case, it was soon after he entered the apartment based on the dog not barking. So, that may indicate he was not in the apartment long enough to strangle her.
Since a previous victim was assaulted in the truck/SUV, it would be resonable to think the Brianna was also assaulted in the truck/SUV rather than in the field. I think the field was just a place to dispose the body. I guess I am deducting that she was most likely murdered in the truck/SUV.
Was she murdered defore or after a sexual assault? LE has stated that the abduction was sexually motivated but I don't think they have stated if Brianna was sexually assalted. If I am correct, it has been stated that a previous victim was sexually assaulted in the truck/SUV then awoke from unconsciousness. Based on that statement, it would be likely that, if Brianna was sexually assaulted, it was after he had rendered her unconscious. I don't know if that was from the hit, that caused the blood on the pillow, or from strangulation. There was a functional reason for him to strangle Brianna and not the other victim he had unconscious. That makes me think that she continued to fight him and he escalted his attempt to subdue her resulting in stragulation. That is a long way to say, I think he murdered her prior to a sexual assault, if there was one, which is most likely.
Just my long winded opinion. What is yours?
