Having followed this case right from the start where I was listening to the podcast when Heidi's friends realised it was Magens house the police were at to magen pleading guilty and being sentenced, this movie doesn't give any viewers who didn't follow the case an ending on what sort of justice was served to Magen, it just ended.
So for the viewers wondering what happened to Megan, she originally tried saying the baby was hers, and after 3 years Magen took a plea agreement and waved her right to any future appeals and Heidi finally got her justice in Feb 2023 when Magen was sentenced to 55 years.
