Written by In 2017, Sergeant Mathieu Nadeau oversaw the investigation of a suicide by firearm. An internal investigation found that he violated Attorney General’s Office protocols for death investigations and failed to maintain sufficient competence. Initially, a one-day suspension without pay was determined, but after grievances, no discipline was ultimately imposed. Additionally, concerns about his truthfulness in handling a traffic accident involving Deputy Jones led to inquiries about potential Giglio impairment, though no sustained findings of untruthfulness were made.
