Kanpitak Pachimsawat, widely known as “Moo Ham”, crashed his Mercedes Benz into a crowd of people in 2007, killing a bus conductor.
The 27-year-old, who has previously sought mental treatment, appeared calm as the verdict was read out yesterday. He has been jailed for two years and one month.
His parents, businessman Kan-anek and former beauty queen Savinee, were not present for the verdict.
Kanpitak was convicted on all counts for killing and injuring others.
According to witnesses, Kanpitak quarrelled with a bus driver and hit him with a rock on July 4, 2007.
The bus conductor and passengers who had to get off the bus due to the quarrel surrounded Kanpitak’s car and loudly complained.
Kanpitak’s younger sister was in the car and broke into tears, resulting in Kanpitak being thrown into a fit of rage.
He said he was lovesick at that time and had not seen his doctor at a psychiatric hospital for more than one month.
Rage blamed on mental health
The Court of Appeals handed him a suspended jail term in 2013 on the grounds he committed the crimes because of his mental-health problems.
The leniency was also based on the fact that his family provided compensation to the victims.
The mother of the bus conductor received more than |Bt2 million. But public prosecutors and a plaintiff petitioned the Supreme Court.
In jailing Kanpitak, the court said despite his mental-health problems he deserved to serve a jail term based on his age, behaviour at the time, and the circumstances surrounding the incident.
