Crime Busters B - 2022 UCSO Crime Busters Test - University of Chicago B - 01-15-2022 Instructions (shown before students start the test) Hello and welcome to the 2022 UChicago Division B Science Olympiad Tournament and more specifically to Crime Busters! You will have 50 minutes to complete this test over the week. Unlike most years, this year’s test will have no lab section, so all of the necessary information will be included in the test section. You will need the information from this document in order to successfully take this test. https://docs.google.com/document/d/19T xAGzMMbpSfFKrG4bwp3Y5Al835z8eLE8AzbqjJio/edit?usp=sharing (https://docs.google.com/document/d/19T-xAGzMMbpSfFKrG4bwp3Y5Al835z8eLE8AzbqjJio/edit?usp=sharing) Introduction (shown after students start the test) The Crime: Once again The Office has faced tragedy. When Hank, the security guard, opened the building and made his rounds, he found a warehouse worker extremely beaten and passed out behind the Dunder Mifflin™ reception desk. Along with that, the place was ransacked with paper, M&Ms, and office supplies all over the place. When the police arrived they noticed a trail of blood coming from the annex, solid #1 on Kelly’s desk, liquid #1 and powder #2 in the kitchen, and a few other powders, plastics, liquids, hairs, and polymers along the way. Lastly, the police found a ransom note on the front desk. When Angela arrived at work, she realized that one of her cats, Bandit, was missing from his place in the filing cabinet, the reason for the ransom note. The police have five suspects in mind: Toby Flenderson, Dwight Shrute, Kelly Kapoor, Ryan Howard, and Roy Anderson. Each of them have been interviewed by the police, and their information can be found below. Your task is to determine who is the guilty party based on the evidence provided (no knowledge of The Office is required to solve the crime). For fingerprints please put the specific type of fingerprint.
