Is the death a murder with poison?

Here are the six critical questions that need to be answered!

(1) What substance was found in the victim that should not be there? = “method”

         - qualitative analysis

(2) Is the substance in a toxic amount? = “method”

        - quantitative ananlysis

(3) Were observed symptoms consistent with the substance and the amount? = “method”

       - witness description

       - autopsy findings

(4) How and when did the substance get into the victim? = “method”

       - by what route?

       - at what time?

(5) Who would gain from the victim’s death? = “motive”

       - study the victim = “victimology”

       - who had a reason?

(6) Who had access to the victim, and the toxic substance? = “opportunity”

       - to the victim

       - to the poison
