Awesome narration Xander !It wasn't a good way to go. Spine snapping wasn't an unusual way of killing someone historically though. Everyone knew about the Wild West, and as common as shootouts were the hangings. Someone stood in place on a raised platform as a noose was tied around their neck, then the platform was removed, the neck snapped, and the criminal or whoever snapped their neck in a swift death.
Except it wasn't always swift. Sometimes when the noose wasn't tied or positioned properly it didn't result in a swift death. The noose dug into their neck, obstructing blood and air flow. It's not as excruciating after loss of consciousness, but that doesn't stop the body from thrashing about. Bonnie? She was already unconscious, so the pain wasn't something she'd take with her to the other side. That didn't stop the body from trying to fight it though. Arms twitched and moved slightly as legs moved and kicked the car door. Her mouth opened slightly as her unconscious form tried to draw air into her lungs, but the arms constricting around her neck stopped that from happening.
Apparently she wasn't going as silently into the night as Avis would have liked.
