Young couple goes on van tour of US, boy comes back with van - no girl

I still don't think a lot of people understand this.. a person can usually lose consciousness in 30 seconds, but take up to 5 minutes of strangulation before they die.
that means while strangling her, she would have lost consciousness pretty quick, and be just kept on strangling her for over 3 minutes before she died.

Also, she wasn't choked, she was strangled. choking is internal and strangling is external force.
This, I mentioned much earlier in the thread that you have to put a lot of effort into strangling someone. It takes strength and stamina. The only thing that would make it easier is if he used a tool of some sort but I don't recall reading anything like that, just strangulation.
