He was shot multiple times in the face, torso, arms and legs and died at Phetchaburi provincial hospital.
The boy said he and Sunthorn were returning home from cow-racing practice at Wat Saowakhon. They were only about 100 metres from Sunthorn’s house when the boy heard a second motorcycle’s engine revving, followed by a burst of gunfire.
Once Sunthorn’s bike was on the ground, a gunman walked up to him and fired several more shots, but ignored the boy.
Sunthorn had stood trial for murder in 2012 but was acquitted for lack of evidence.
