South Korean police recovered the dead body of a Vietnamese woman from a gorge in the south-western province of Chonlanam-do on Tuesday.
Police said Do Thi My Tien, 27, was murdered five days before by a killer who then pushed her and her motorbike off a mountain road to make her death seem accidental.
Tien was married to a Korean man in 2004. The mother of an 8-year old boy was then granted South Korean citizenship.
Her husband was summoned to the police station for questioning.
Tien’s Vietnamese neighbors told Vietnam News Agency that she and her 47-year old spouse had argued before her mysterious disappearance.
The Vietnamese women married them hoping for fairy tale lives. Instead, most suffered from steep language and cultural differences.
In March 2012, the South Korean consulate in Vietnam announced that a Vietnamese woman had been killed by her husband in South Korea.
