# Đồng Nai mass murder investigation > Live situation record from CLSTR: https://clstr.news/situations/ng-nai-mass-murder-investigation > Updated: 2026-09-07T13:46:02.000Z. Sources: 11. Developments: 3. In September 2026, police in Đồng Nai arrested 21-year-old Nguyễn Đức Anh for murder and the unlawful use of military-grade weapons following a mass killing in Bình Minh Commune on September 3. Investigators stated the suspect sought revenge against a former romantic partner, identified as Đ. T. P. A., following a recent breakup. After failing to enter the partner's home by climbing onto the roof and attempting to break through a skylight, the suspect moved to an adjacent residence belonging to N. V. Q. Upon entering the neighbor's home, Đức Anh attacked the occupants, resulting in the deaths of a 36-year-old woman and her two children, aged 11 and 1. The husband, 40, sustained serious injuries and is receiving treatment at Thong Nhat Dong Nai General Hospital, though he is reportedly out of critical danger. Legal experts have noted that because the suspect had no prior relationship with the family and entered the home without permission, his actions may warrant additional charges regarding the violation of residential sanctity under the Penal Code. ## Timeline ### 2026-09-07: Dong Nai police charge suspect in fatal triple murder case Police in Dong Nai have charged Nguyen Duc Anh with illegal use of military weapons following a fatal home invasion that killed a mother and her two children. 6 sources. https://clstr.news/cluster/dong-nai-police-charge-suspect-in-fatal-triple-murder-case ### 2026-09-05: Đồng Nai police charge suspect in fatal multi-person attack Nguyễn Đức Anh, 21, has been charged with murder and illegal weapon use after killing a woman and two children in Đồng Nai, Vietnam, following a failed attempt to attack his ex-girlfriend. 10 sources. https://clstr.news/cluster/dong-nai-police-arrest-suspect-in-fatal-triple-murder ### 2026-08-19: Da Nang court reviews murder trial of delivery driver death A Da Nang court has requested further investigation into a murder trial involving three individuals accused of killing a delivery driver following a dispute over a 375,000 VND payment. 2 sources. https://clstr.news/cluster/da-nang-court-reviews-murder-trial-of-delivery-driver-death --- Cite as: Đồng Nai mass murder investigation.
