Sammy Mean, a guest at the party who knew both the
appellant and deceased, saw the appellant walk out of the restaurant into the corridor. He was carrying two beer bottles behind
his back. He hit the deceased with the beer bottles. The deceased
stumbled. The appellant then stabbed the deceased in his side
with a knife he had in his left hand.
 Rin Ken, who is Vanny Phann’s aunt, decided to leave
after the deceased argued with the event organizer. She saw Kim
struck on the head, and that he had been stabbed in the stomach.
She later saw a man open a folding knife. She then saw the
deceased had been stabbed.
 The deceased, Kim and Phann ran in different directions
in the mall after the fight. The deceased, clutching his side,
headed south towards the vestibule, the appellant in pursuit of
him. Both the deceased and Kim were taken to hospital in the
back of a pickup truck.
The video surveillance evidence
 A central feature of the evidence adduced at trial was
a three-minute segment recorded on various surveillance cameras
throughout the mall, as well as a series of still photographs taken
from the videos showing the appellant’s involvement. The appellant is clearly visible because of the distinctive white shirt and

 On the video, the appellant approached a small group of
people standing outside the restaurant, talking. The group
included the deceased, his wife, Mao Kim and Vanny Phann. The
appellant spoke to them for several seconds. The appellant had
a beer bottle in one hand and possibly some other object in his
other hand. He put both hands behind his back, then stepped
back as the deceased spoke to him gesticulating with his (the
deceased’s) arms wide open.
 Within ten seconds, the appellant struck the first blow in
the direction of the deceased and Kim. Beer spilled on the floor.
The appellant and deceased moved out of camera range. Other
fights started. Within seconds, blood spattered on glass doors
from the direction in which the appellant and deceased
had headed. The deceased stumbled back into the frame covered
in blood on the right side of his shirt. Knocked down by
a co-accused, the deceased regained his feet and headed towards
an exit, a trail of blood behind him.
 The appellant followed the deceased down a hallway
pointing towards him with what appears to be a knife in his
