In this photo taken Sept. 30, 2011, Al Grasch is seen in Forkston, Pa., inside the cabin where his son David Grasch and two of David's cousins died under mysterious circumstances in November 2006. Pennsylvania State Police said Tuesday March 20, 2012 they now believe that carbon monoxide poisoning likely killed three men inside a mountain cabin in 2006 after new tests were conducted in the wake of a story by The Associated Press that raised questions about suspicions it might have been a triple homicide.
