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.
Cui Hao
Modern historian Bo Yang believed there to be two probable reasons to Cui's death:Bo's analysis is itself speculation, but might be considered a reasonable explanation for what happened to Cui. Bo also believed that Cui was poisoned—which would explain why he was not able to respond at all to Emperor Taiwu's interrogation, and was later only yelling "Ao Ao" in lament, unable to say anything.
