1. Blood toxicology screen is clean.

6. What was the cause of death? (one sentence)

8. The body was found at 3:00 pm on a Tuesday. Estimate the possible time of
death. Provide a range and explain your answer. (one to three sentences)
9. Dr. Fisher was found lying on his back. Is it likely that his body was moved after
death? Why or why not? (one to two sentences)
10. The white powder on the table was also tested. It turned out to be an unusually
high-quality blend of an illegal drug. Was Dr. Fisher under its influence at the
time of death? How can you tell? Speculate on what this evidence could mean
for the case. (three to five sentences)

10) No because toxicology report was clean. Had he been under the influence of drug the toxicology report would have detected traces of drug. A person doesn't die instantly under the influence of drug. The heart has already pumped blood around the body when the person die so toxicology report can't be clean.

Explanation:

8) a general formula for hours since death is: (98.6 - body temperature when body is found)/1.5

Here temperatures are in Farenhite. Assuming room temperature to be 72 degree Farenhite,

hours since death= (98.6-72)/1.5

= 17.73

Back counting from 3pm, it is between 9pm to 10pm a day earlier
