Prosecutors in the southern province of Binh Phuoc on Monday ratified a decision to detain and launch a criminal investigation into two men for allegedly killing six members of a wealthy family before taking their money and valuables.
Nguyen Hai Duong and Vu Van Tien, both 24, will be detained in four months for investigation on “murder” and “robbery” charges.
The brutal case has shocked the country for the past week.
Police with the Ministry of Public Security told the press they arrested the two suspects, who confessed to their crime, just three days after the murder.
According to the police, Duong is the ex-boyfriend of Le Thi Anh Linh, the 22-year-old daughter of Le Van My, 48, who owns a timber processing company in Binh Phuoc’s Chon Thanh District.
After Linh broke up with him in April, Duong devised a plan to kill the family and rob them, police said.
To prepare for the crime, he bought two knives, a stun gun, a BB pistol, gloves, masks, plastic cable ties and duct tape.
On July 6, Duong persuaded his friend Tien to join him.
At around 8 p.m. that day, Duong phoned Du Minh Vy, My’s 14-year-old nephew, asking the teenager to open the gate for him later so that he could sneak in and steal something. He promised to give Vy some money.
At about 2 a.m. on July 7, Duong and Tien drove a motorbike to the house, which is located on National Highway 13.
Police said they killed Vy immediately after he opened the gate.

They then killed all the other five victims -- his ex-girlfriend Linh, her parents, her 15-year-old brother, and another cousin, police said.
They however spared the life of Linh's 18-month-old sister who was sleeping in the bedroom, police said.
They left the house at around 4.30 a.m. on July 7 with about VND4 million (US$183) in cash, five smartphones and a tablet, police said.
Local police was informed of the murders three hours after by a housekeeper of the victims' family.
Police said they found the murder weapons, cash, phones and tablet in Tien's house.
Duong was arrested at 3 p.m. on July 10 in Binh Phuoc.
Tien was arrested five hours later in his house in Ho Chi Minh City's Hoc Mon District.
