Olivia Wilkins of Thomaston pleaded guilty in March to assaulting a U.S. Border Patrol agent engaged in official duties, and could have spent up to 20 years in prison. Prosecutors say Wilkins drove at a border patrol agent who was taking a person into custody at a crash scene in Washington, Maine, and then left the scene. They say Wilkins stopped her car short of hitting the agent or the individual in custody before swerving back into the lane of travel and fleeing the scene.
