Well when Aaron Hernandez did it in prison he put soap on the floor so he could not stand up even if he wanted to.Hanged herself from a door knob with a scarf. How tall was she? How is that even possible?
Hanging isn't about choking/asphyxiation. It is about inertia and pulling the base of the spinal cord from the base of the brain.
But i have little doubt that the way she and Hernandez did it involved choking to death.
