Kou Voravong
The attack occurred at approximately 22:15, at Phoui Sananikone's, an official residence nearby the Voravong family's. The attackers launched three grenades by one of the windows on the ground floor, in the dining room. They fired three or four pistol shots and then run away. Kou voravong, sitting with his back to the window, was directly hit by a bullet which came in by the kidney and out through the navel, after cutting the vena cava and crossed the liver and intestines. His dead is declared shortly after admission to hospital. A dozen people were injured by the explosion of the grenades, slightly for most of them.
Kou Voravong
To close the file definitively, in July 1959, the 9th Royal Government, chaired by Phoui Sananikone, brought the case to trial quickly and behind closed doors, dealing exclusively with the assassination of Kou Voravong, in order not to revive "old issues". Apart from that of Oudom Louksourine – sentenced to death in absentia – no other name was pronounced and the judgement legally exonerated Phoui Sananikone of all charges.
