While searching through recipes and content to find perfect Halloween fodder for the blog, I remembered that when I wrote about Edna Ruth Bullock, I had mentioned that I had another “killer” story to share. (Kind of punny). So in honor of Halloween and all things horror, let me introduce you to Ma Duncan. A plain, simple woman that was guilty of maybe loving her son too much. While women frequently have tenuous relationships with their mothers-in-law, I don’t know of anyone whose mother-in-law has tried to kill them.
