Update: Courtney Plante has taken a plea agreement in regard to attempted-murder allegations against her and significant other Sean Overstreet dating back to January 2016, when she was nineteen and he was 37. The deal trims time off Plante's possible sentence but doesn't let her off the hook for a crime against a former teacher of hers that was as violent as it was bizarre. According to the original arrest affidavit, Overstreet stabbed Michael Brown multiple times while Plante allegedly encouraged him via comments such as, " Go get him, Sean ."
