Officer Blake Devillier has faced multiple allegations of misconduct. In 2017, while employed with the LSU Police Department, he was accused of domestic violence against his girlfriend and abuse toward his K-9 partner, Tessa. The victim reported incidents of physical assault and mistreatment of the police dog, leading to a protective order being filed against him. Devillier resigned from LSU Police following these allegations. In July 2023, as a member of the Zachary Police Department, he was placed on leave after a complaint alleged he struck a child in the back of the head. The department initiated an investigation into this incident.
