Anthony E. Zuiker, the creator of the "CSI" franchise, begins production on his first primetime reality series, Whodunnit? Cris Abrego partners with Zuiker for the new nine-episode alternative series that puts 13 contestants' investigative skills to the test in a mystery reality competition. Each week players will use a variety of crime scene investigation techniques to meticulously uncover evidence that will ultimately reveal who among them is the killer. The interactive series will pit 13 amateur sleuths against each other in a quest to solve a series of puzzling murders. Some will form alliances and others will choose to go it alone just to get them closer to the grand prize. The contestants will reside on a glamorous estate where each week they must solve a new crime in order to advance in the game. Failure to solve the crime will lead to a player's demise, until only three are left. In the final episode, one player will unmask the killer and take home the $250,000 prize.
