Crime Busters

Welcome to Crime Busters! In this event, given a scenario, a collection of evidence, and possible suspects, students will perform a series of tests. Test results along with other evidence will be used to solve a crime and answer questions.

The information below should not be interpreted as an extension of the rules. You can find free online copies of the current rules for download on the 2027 Rules page of the Science Olympiad website. The official rules in the current Rules Manual take precedence.
