The family of Huynh Thi Vui, the 29-year-old woman who married to a Taiwanese man via a brokerage service, said they have been out of touch with her for three years now.
On Friday, Tran Thi Dien, Vui's mother, told Thanh Nien she could not contact Vui via telephone and that marriage brokers claimed to have no idea where she is.
In 2004, Vui left her hometown the central province of Thua Thien-Hue for Ho Chi Minh City to work.
She was introduced to a marriage-arranging agent in the hopes of finding a foreign husband.
In January 2005, she married a Taiwanese man 20 years her elder. One month after their marriage, the couple relocated to Taiwan.
Vui gave birth to a baby girl the following year. She called home saying she was living with her husband and his parents, but her husband was addicted to gambling and beat her regularly when he lost, Dien said.
She said her husband's brother was also addicted to gambling and often borrowed money from her. If she refused to lend him money, she would be beaten by her husband as well, according to Dien.
In early 2008, Vui called home to get her family's address so that she could send her parents money to cover their debts.
It was the last time she called home. Dien said she tried to contact Vui through the mobile phone Vui used to call but was unable to reach her.
She called marriage brokers but they said they had no idea where Vui is living.
Huynh Van Hai, Vui's father, said the family did not report to Vietnamese authorities about the case because they themselves had little information about their daughter's husband.
