About Marius

Marius Mason is a transgender environmental and animal rights activist and anarchist. In 1999, in the name of the Earth Liberation Front (ELF) he set fire to a lab at the University of Michigan that was conducting research on genetically modified organisms (GMO). After Marius’ husband turned state’s-evidence, Marius was threatened with a life sentence for the arson and other acts of sabotage. With little financial stability and fear of dragging his family into a costly legal battle, Marius pled guilty and was given an extreme sentence of nearly 22 years. No one was ever harmed in any of his actions.
