A FROZEN AND PUZZLING CRIME SCENE LEAVES A LOT OF THE GUESTS OUT IN THE COLD, ON ABC'S "WHODUNNIT?"

"Frost Nixin" - With only a handful of guests left, the killer is getting more and more inventive, somehow turning a hot tub into the scene of the next victim's frozen demise. If that weren't enough, the remaining four guests are thrown a curve ball when Giles announces that there'll be four instead of the standard three locations to investigate -a mystery location has been added, and they'll have to compete to see who will get access to it -- on "Whodunnit?," SUNDAY, AUGUST 11 (9:00-10:00 p.m., ET) on the ABC Television Network.

"Whodunnit?" is an interactive series that puts 13 amateur slueths' investigative skills to the test in a riveting mystery reality competition. Players will use a variety of crime scene investigation techniques to meticulously uncover evidence in a series of puzzling murders and to ultimately reveal who among them is the killer. Some players will form alliances in the competition, while others will choose to go it alone in their quest for the grand prize of $250,000. The contestants will be guests on a glamorous estate called Rue Manor with a steward, Butler Giles (Gildart Jackson), and each week 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.

The Remaining Guests Are:

Cris, 27, a former beauty queen from Costa Mesa, CA
Kam, 30, an attorney for the Department of Homeland Security from New York, NY
Lindsey, 27, a senior engineer from Boston, MA
Melina, 29, a flight attendant from Chicago, IL
