They say he was found lying on the floor, unconscious with food in his mouth - apperently choked to death. One thing I am kinda curious about is this - if someone is choking, seems one would spit out the food in their mouth as they are trying to do anything to get that food dislodged thats deep down in the throat/windpipe. Now I don't know if the food in his mouth was the food that Josh dislodged or what. Choking to death isn't immediate - it's going to take some time before one passes out, whether that's 30 seconds or 2 minutes hell I don't know. My point IS, if he had a heart attack or stroke, while eating, it would make more sense of still having food in his mouth, as they are immediate if severe.
Anyways I remember as a 10 y.o kid I accidently swallowed one of those big gum balls and it was one of my scariest memories. Not being able to breath you go into an instant panic. My mom gave ne a hard slap on the back and it popped out.
Btw not trying to fall into the speculation crowd regarding Dallas. Just making an observation with the information given at this point.
