MURDER MYSTERY: Stoichiometry Edition You are the lead investigator on the case of a murdered athlete. You must find out how the victim was killed and who killed him, using your knowledge of stoichiometry. Read the instructions, find the evidence, and solve the case. Victim information: Case # 153 Name: Jasper Chan Sex: M Height: 5' 10" Weight: 154 lbs Information : The victim is a minor league baseball player for the Kane County Cougars . He lived alone in a one bedroom apartment 5 blocks from the stadium. His teammates say he was a nice guy. He has a mother and younger sister in Seattle, WA. This was his first season with the Cougars. He played for the Quad Cities River Bandits for two years before transferring to the Cougars in December. When he wasn't practicing or traveling with the team he played a lot of Xbox. There was no sign of injury on the body so you suspect the victim was poisoned. You instruct the lab to do a toxicology screen and look for poisons. When you get the toxicology report back you find out that the lab tech forgot to convert the moles of toxic metals into grams. Luckily, you paid attention in chemistry and remember how to do those conversions. Toxicology report for case # 153 There were traces of lead, arsenic, mercury, and chromium in the blood. Very small amounts of these toxic metals will not kill a healthy adult, but if the dose is high enough the individual will die. The amounts of toxic substances found in the body are listed below.
