"In 2004, when he was 20 years old, Tarrio was convicted of theft. He was sentenced to three years of probation, community service, and ordered to pay restitution. In 2013, Tarrio was sentenced to 30 months (of which he spent 16) in federal prison for rebranding and reselling stolen medical devices."
