Warning Signs Missed Before Fatal Crimes Driven by Jealousy and Revenge

The latest case happened on June 20 in Viet Yen Ward, Bac Ninh Province, leaving five people dead or injured. Nguyen Van Tuyen attacked several family members of N.T.N. after a relationship conflict and then took his own life. The attack was very violent. Many people are shocked by the news. The police are investigating the case. The family is very sad.
The attack left N.T.N., her two children, and Tuyen dead. A girl was injured and is still in the hospital.
Earlier cases show a similar pattern.
In Gia Lai Province, a jealousy-fuelled attack on October 18, 2025, left four people dead or injured. Nguyen Anh Duy allegedly set a spa on fire. The spa was owned by his lover, T.T.T.N.
The woman died at the scene. N.B.C., the victim's former husband, later died from his injuries. Their child suffered severe burns, and Duy was injured.
Authorities later charged and detained Duy for murder.
Another case in 2025 shocked the public in Phu Tho Province.
At around 8:10pm on September 26, 2025, Vu Phuong Nhung allegedly stabbed Nguyen Van N. and Cao Thi Y. Both victims died at the scene. The attack happened on a road in the Phu Ha Industrial Park area.
After the attack, Nhung travelled to the home of Nguyen Tien D. and fatally stabbed him. He was arrested by police the following day.
Long-term resentment, jealousy, and revenge are common themes in these cases.
Lawyer Diep Nang Binh said these cases represent particularly serious murders that demonstrate an extremely high level of danger to society.
A common characteristic is that offenders often accumulate resentment, jealousy, or a desire for revenge over time. When they can no longer control their emotions, they resort to violence.
Many cases show evidence of preparation, including the selection of weapons, timing, and locations. Some offenders planned attacks against multiple victims.
Under Vietnam's Penal Code, murders involving two or more victims or children are considered aggravating circumstances and can carry the maximum penalties.
Where an offender dies by suicide after committing the crime, criminal liability ends under the law.
According to Binh, many offenders come to view spouses or partners as the source of their personal grievances and seek revenge through violence.
Such thinking is extreme and represents a serious violation of both the law and social morality. No relationship conflict can justify taking another person's life.
The recent cases also underscore the need to identify warning signs at an early stage, including domestic violence and threats.
When such signs emerge, victims and their relatives should report them to authorities so that preventive measures can be taken.
The legal consequences of these crimes are severe. The greatest tragedy remains the lives lost and the lasting pain inflicted on families.
The cases could have been addressed through dialogue and lawful means. The families are still suffering.
