Murder under the Microscope investigators have been solving mysteries since 1995. For each case, EcoSleuths all over Australia have researched and analysed evidence to solve an environmental crime. Explore the last five cases using the links below.

In Murder under the Microscope, students are presented with an eco-crime they must investigate. Working as a team, students study the issues and crime sites, research the victims and villains and use the clues provided by Catchment Headquarters to try to solve the mystery.

Resources such as a teacher's wiki, timeline of events, activity cards and other support materials are provided to assist teachers in supporting their students.
