It was the trial that defined a generation. This January, Investigation Discovery (ID) in association with Objective Media Group challenges everything you think you know about the trial of O.J. Simpson in a riveting new six-part docu-series Is OJ Innocent? The Missing Evidence. Narrated by Emmy Award-winning actor and activist Martin Sheen, and featuring exclusive new interviews with the families of Nicole Brown Simpson and Ron Goldman, the series follows investigators as they re-open the case that captivated the world, exposing the facts that were overlooked by authorities and questioning and dissecting each pivotal move in the original investigation.

From the infamous Bronco chase to updated forensics and DNA data to the examination of a potential murder weapon, each hour-long episode explores new possibilities and theories about what might have really happened on that fateful summer evening more than 20 years ago.
