One of the two witnesses whose testimony reportedly convinced prosecutors to drop all charges against Red Bull scion Vorayuth "Boss" Yoovidhya died following a motorcycle crash in Chiang Mai early yesterday.
Jaruchart Maadthong, 40, was involved in a motorcycle crash at 1am. He died shortly after at Maharaj Nakorn Chiang Mai Hospital.
His family and relatives said they knew nothing about his involvement in the high-profile case, Thai media reported.
The Chiang Rai native was one of two new key witnesses added to the case two years ago. The other was a retired officer, Air Marshal Jakkrit Thanomkulabutr. Both testified that the Ferrari was travelling at 50-60kph when the crash occurred.
The witnesses also testified that they saw a policeman on a motorcycle cut in front of Mr Vorayuth's Ferrari. As a result, the dead policeman was named as another suspect in the case alongside Mr Vorayuth.
