Pol Lieutenant Amnart Onpan, who is investigating the death, said Sitthikorn’s younger brother Thawatchai showed police Sitthikorn’s will.
Thawatchai informed police that in early October Sitthikorn told him to follow what was in the will – but he thought his brother was joking, the officer said.
Handwriting in the document matched writing in a suicide note left in the Phitsanulok hotel room where Sitthikorn’s body was found on Thursday night.
There was no sign of a struggle in the room. The hotel is located in Muang district.
Amnart quoted Thawatchai as saying he chatted with Sitthikorn via Line without knowing his brother would later overdose on sleeping pills. Amnart said police were waiting for the autopsy results to confirm the cause of death.
In his suicide note, Sitthikorn asked his younger brother not to hold funeral rites for him but simply cremate his body. However, the family said there would be rites at a ceremony at Wat Suwanrangsan in Rayong.
Sitthikorn’s elder brother Chaowalit Boonchim, who went to the morgue with Thawatchai to collect the body, said Sitthikorn was the third oldest of five brothers.
Banchangkanchakul Wittaya School teacher Darun Khongtharat and her son Piano were also at the morgue. Darun said she knew Sitthikorn since 2003 and Sitthikorn had actively supported youth promotion activities and granted 57 scholarships to children that enabled many kids to graduate from university with a bachelor’s degree.
