The Fairfax County Police Department has released body camera footage of a fatal domestic incident involving a Nepali family in Mantua, Virginia, nearly 24 days after the incident.

The footage, made public through US media on March 19, documents the tragedy following the attack that occurred at around 5:15 am on February 24 in Fairfax County.

Police said 54-year-old Chhatra Bahadur Thapa, originally from Belaka Municipality in Udayapur district, allegedly attacked his 51-year-old wife, Binda Thapa, and 31-year-old daughter, Mamata Thapa, with a sharp weapon. Both women died at the scene.

According to police, officers responding to a 911 call from a neighbour reporting screams arrived to find the suspect inside a blood-stained apartment, holding the weapon and continuing the assault on his son-in-law, Santosh Kumar Basnet.

Despite repeated orders to surrender, Thapa refused and attempted further attacks. Police then opened fire, and he was pronounced dead at the scene.

Basnet, who sustained serious injuries, is undergoing treatment at a local hospital. Police said a one-year-old child present in the apartment was rescued unharmed and placed under protective care.

Police Chief Kevin Davis said officers intervened in time to prevent further loss of life, noting that any delay could have proved fatal for the injured victim.

The footage shows a bloodstained apartment and captures the moments leading up to the police shooting, including repeated warnings issued to the suspect.

This is the second such case involving a Nepali family in the United States within a year. In August last year, a Nepali man in Dallas, Texas, fatally shot his wife and young son before killing himself, according to US authorities.
