Stein Havard Dokset, 50, admitted on Wednesday to killing Rungnapa 'June' Ratchasombut but insisted her death was accidental.
He told police she lost consciousness and died after they had an argument and he pushed her down the stairs.
More than two and a half years later, police on Tuesday found Ratchasombut’s decomposed remains in a wheelie bin in a downstairs laundry space at his seven-bedroom home in the Kata beach resort, local newspaper Phuket Wan reports.
A Phuket court ruled on Thursday to hold Dokset in custody for a minimum of twelve days pending a new remand hearing, Aftenposten reports.
Thirty officers swooped on Dokset’s home after relatives of his Thai former girlfriend expressed suspicions he may have been involved in her disappearance, Phuket Wanreported.
On opening a plastic bin in the basement, police were assailed by an overpowering stench. A search led them to the victim’s decomposed remains. She was 30 years old at the time of her disappearance.
