This weekend, Investigation Discovery will kick off their three-part special on Casey Anthony’s case — appropriately titled Casey Anthony: An American Murder Mystery. And while the disappearance of her daughter, Caylee, and her subsequent murder trial were widely followed by the public — which helped the case earn the title of “social media trial of the century” — there are still some key facts that people may not remember about the case.

While the three-part special — which kicks off on Sunday, at 10 p.m., with subsequent episodes airing at the same time the following two nights — promises to provide new revelations about the case that “outraged the nation,” in the five years since she was acquitted for the murder of her daughter, there are many things that people may have forgotten about the 31-year-old’s trial.
