The Marshfield News Herald reports Teschler will provide full and truthful information about Shaun Rudy in exchange for immunity, and to protect her from any further prosecution relating to her testimony.
Prosecutors say she withheld information from authorities and helped Rudy, who's charged with shooting and killing his wife, Christine, and their unborn child.
Teschler's charge of aiding a felon will likely be delayed for a year, and she'll likely be placed on one year probation for her charge of resisting or obstructing an officer. She could also get nine months in jail.
