PEOPLE is expanding its true crime storytelling with the Monday night premiere of People Magazine Investigates, a new TV series on Investigation Discovery that will reveal fresh turns in some of the most gripping and mysterious cases in American history.

The 10-episode series launches with the story of Shannan Gilbert, whose 2010 disappearance on Long Island, New York, led to the discovery of at least 10 more bodies — and a possible serial killer.

Tracking the devastation of the victims’ families and the fervent search for justice, the two-hour special will include exclusive new revelations uncovered by PEOPLE’s experienced crime reporters.
