I agree. The OP drew a conclusion, and rather than just demanding proof I wanted to point out why I didn't think it was obviously true. There would very well be other things not in my analysis that could lead the OP to that conclusion.
For example, methods besides chemical traces might determine the cause of death. Friends of the deceased might provide information about the circumstances of death, additional drugs or paraphernalia might be in the pockets of the victim, or in the immediate surroundings.
In addition, if it were true then there should be a lot more people who are injured in similar circumstances. The medical personnel at the hospital may learn some of the background context when asking for details about what happened to cause the injury.
