On the 23rd of December 1991, a devastating fire destroyed the home of Cameron Todd Willingham and his family.
Willingham made it outside whilst his 3 children - 2 year old Amber Louise Kuykendall and 1 year old twins Karmen Diane and Kameron Marie Willingham perished inside the blaze. The mother Stacy Kuykendall was shopping for presents at the time.
Without going into too many details (I don't want to "spoil" the story for those that don't know but can provide full details if required), since his conviction there have been many doubts as to Willingham's guilt and even as to whether or not a crime was committed.
