After killing his wife and children, he cried and apologized to his mother and then turned himself in.

Tay Ho District Police (Hanoi) said they have temporarily detained Quach Van Nam (born 1989, residing at alley 378/65 Thuy Khue, Buoi ward) to investigate the murder of his wife and son.

At around 9am on May 2, due to a conflict in their marital relationship, Nam used a knife to slash his wife, Duong Khac H. (born in 1999, residing in Nghia Do ward, Cau Giay district) and son Quach Phu T. (2 years old), causing both mother and son to die.

The incident shocked many people around.

"I heard the couple arguing, thinking it was just a normal argument like usual, but then around 9am, the police came and asked to open our house, only then did we know he had murdered his wife and children," said Mr. Hung, a resident living near the scene of the incident.

Mrs. Nga (Nam's mother) sadly shared that she raised her son alone since he was young because her husband left. Nam had only been married for 2 years and had 1 son.

Nam’s family has just moved to live on the second floor of his 90-year-old grandmother’s three-story house. Here, Nam takes care of her and helps her collect rent from the tenants on the first floor.

"I came back from the market and met him at home (where Mrs. Nga was staying). He cried and said he could no longer serve his mother. I asked him what happened and he said he had just killed his wife and son. At that time, I didn't believe it was true.

After saying that, he walked to the police station to confess. Only after the police arrived did I know it was true. I couldn’t sleep all night, lying there looking at the family photos, crying for my children and grandchildren,” Mrs. Nga sobbed.

Head of residential group number 3, residential area number 1 Bui Quang Hy said: “The police called me to the scene to witness the incident. Up until now, in this area, he has had no bad reputation, has not quarreled with anyone. Normally, he still goes to work, buys pho for his grandmother in the morning, and cooks for her after work.

Maybe yesterday the couple argued and Nam was so frustrated that he couldn't control himself. Nam's family is poor, his mother sells scrap metal to make a living."
