"Who Killed Garrett Phillips?" is a documentary project about an unsolved crime that led to a prosecutor losing his job. The story takes place in a peaceful town, where a child unexpectedly dies in broad daylight. In 2012, a boy named Garrett Phillips was found strangled in his home in Potsdam, a provincial town in northern New York state. The main suspects were a football coach and a former lover of Garrett's mother. As the investigation unfolds, the case becomes increasingly convoluted. The killer was never found.
