The incident occurred at the house of his in-laws where he lived in Phong Phu Commune, Tan Lac District.
He stabbed his wife, parents-in-law, and sister-in-law. His 15-year-old son was also stabbed when trying to stop him.
Phien only stopped and fled when local residents heard the screams and rushed in to restrain him.
Initial investigations showed that Phien had quarrelled with his wife and sister-in-law before attacking them. The wife managed to escape.
The 65-year-old mother-in-law died of serious injuries while the father-in-law and sister-in-law were being treated at the hospital. His child also suffered from slight injuries.
Hoa Binh Provincial Police Department sent hundreds of policemen to search for Phien right after the incident. However, the search is facing difficulties due to heavy rains caused by Storm Maon. Police have informed local residents about the incident and asked for co-operation in helping arrest Phien.
