The gun used in the fatal shooting of a popular net idol belonged to the father of her military cadet boyfriend, who was found dead with her, police said on Thursday.

The bodies of Supitcha “Gigi” Predajaroen and her boyfriend Phumiphat “Ikkyu” Chaiwanichya were found, each with a gunshot wound to the head, in a unit of a condominium near the Asok-Phetchaburi intersection in Bangkok on Wednesday afternoon.

Phumiphat, 21, studied at the Armed Forces Academies Preparatory School. He was a son of Gen Somchai Chaiwanichya of the Royal Thai Army who retired last year.

Supitcha, 19, was studying at Chulalongkorn University. She also performed with the girl group One Day to the Next and more recently with Kisskazz. Her profile made her a popular online influencer for cosmetics and other products on her Facebook and Instagram accounts. The latter had 177,000 followers.

Police believe the man might have shot the woman and then taken his own life.

The incident might have stemmed from the pair’s personal relationship, police said.

The initial examination showed that the man was likely to have been the perpetrator.

Supitcha's mother said on Thursday that the cadet used to physically assault her daughter, and that his family was aware of the abuse. The couple had broken up earlier but then resumed their relationship.

She said she often told her daughter to be more careful as her boyfriend often played with guns and carried them. She was worried that he might assault her daughter again if they had a quarrel as he was hot-tempered, she added.
