Key Witness in Kaczynski Plane Crash Case Found Dead

A key witness in the case of the Polish Tu-154 airliner crash near Russia's Smolensk in 2010 has been found dead at his home near Warsaw.

A Polish prosecution official has said that investigators believe the man committed suicide.

The flight engineer of a Polish Yak-40 plane, Riemigiusz Mos, was found hanged in a Warsaw suburb late on Sunday, The Voice of Russia informs.

The body was found in the basement of a residential house where he lived together with his wife, the prosecutor's office official said in a live interview with Radio Poland. According to him, neither police, nor prosecutors have reasons to suspect that third persons could be involved in the death of the 42-year old Mos.

On April 10 2010, the Polish government TU-154 took off on its way to Katyn to commemorate 70th anniversary of the Katyn Massacre. The plane crashed near Smolensk during landing killing all on board.

The Voice of Russia has reminded that Mos was in the cockpit of his Yak-40 airliner that landed at Smolensk-Severny airport just one hour before the presidential Tu-154 had attempted to land at the same airport but crashed, killing all 96 people on board, including Polish President Lech Kaczynski. Mos could hear the communication between the Tu-154 crew and the Smolensk air traffic controllers via his onboard radio.
