'A Polish parliamentary investigation into President’s Lech Kaczynski plane crash in Smolensk in 2010 is considering witness protection: A flight engineer set to deliver critical testimony was found hanged in his house in Warsaw.
The body of Remigiusz Mu?, a 42-year-old aviation engineer, was found by his wife in the cellar of their house in the suburbs of the Polish capital at around 11:30pm local time on Saturday. She called an ambulance and attempted to resuscitate her husband, but medics pronounced him dead as soon as they arrived. An autopsy is set for Monday, October 29.
As news of Mu?’ death hit headlines, the head of the Polish parliamentary commission looking into the crash, Antoni Macierewicz, said that Mu? was one of two key witnesses in the case. With Mu? dead, key witness Artur Wosztyl should be put in protective custody, Macierewicz said.'
