Forgot to add, she also had congestion in her lungs and had changes in her pancreas consistent with death due to strangulation. She had petechial hemorrhaging on her heart also.
I have no links. I googled the subject and read maybe 100 results.
"consistent with death due to strangulation"
But, you're saying, NOT consistent with head trauma. It's how you are EXCLUDING that as a possibility that I'm not getting. I googled it, too, and found references to the causes of petechial hemorrhaging. I was surprised to find that it is NOT solely related to strangulation.
Also, a semantics issue. The material issue in this question of which event occured first has to do with strangulation, not asphyxiation. There can be many causes of asphyxiation and strangulation is only one of them.
