On January 16, 2002, first-degree murder charges for the killing of Myrna Opsahl were filed against Olson and four other SLA members: Emily Harris, Bill Harris, Michael Bortin (Olson's brother-in law who had married her sister Josephine), and James Kilgore, who remained a fugitive. Judge Fidler arraigned Olson on the murder charges immediately following her sentencing hearing on January 18. Olson pleaded not guilty to that charge at the time, but on November 7, she changed her mind and pleaded guilty. She was sentenced on February 14, 2003, for the maximum term allowed under her plea bargain, which was a six-year term concurrent to the 14-year sentence she was already serving.
