Quick Summary

Trysten Mullis is trying to exonerate his father Todd from the conviction for murdering his mother Amy on their Iowa farm in November 2018. On the day of the incident, Trysten, then aged 13, was helping his parents prepare baby pigs for shipment while his siblings stayed at home. When Amy appeared unsteady and dizzy shortly after returning from a minor medical procedure, she agreed to rest inside but promised to retrieve a pet carrier from a shed before doing so. An hour-and-a-half later, when the pet carrier wasn't outside as expected, Trysten discovered his mother's body in the shed with a corn rake in her back, leading to Todd's subsequent conviction for murder.
