Video footage from security cameras has shown that a suspect who allegedly committed the murder of a married business couple in Vietnam’s Mekong Delta on Sunday is about 1.8 meters tall.

The suspect was seen at the couple’s house around 1:45 am in the video clip extracted from the security cameras installed at the residence in Cai Lay Town, Tien Giang Province, a Tuoi Tre (Youth) newspaper source said.

The person then stabbed the couple several times with a knife before cutting their throats in their bedroom on the second floor of the house, according to the footage.

The evidence also pointed out that the suspect intruded into the home of the victims by climbing over the fence.

On Sunday morning, local people in Cai Lay Town, Tien Giang were startled as Luong Van Dau, 67, and his 63-year-old wife, Vo Thi Nam, were found dead in their own bedroom.

The two were owners of the Huu Khanh coffee processing company, the largest such firm in the area.

The couple were discovered dead at their house, which is also the main office of the company, by Tran Van Phuoc, who is Nam’s nephew.

A 14-year-old grandson of the couple was also present at the house at the time of the incident. However, he is safe, as he was sleeping in another room.

Officers from the provincial department of police as well as from the Ministry of Public Security then arrived at the scene to investigate the case.

At 4:00 pm yesterday, inspection at the scene was completed and the bodies of the deceased victims were brought to a local general hospital for an autopsy.

The couple began the business operation of the Huu Khanh coffee processing firm, which is managed by one of their sons, in 2009 by distributing coffee products to Ho Chi Minh City and other provinces in the Mekong Delta, with an annual revenue of VND60 billion (US$2.67 million), a business partner said.

Their house was built two years ago and the two victims only lived there for about three months.

They rarely interacted with their neighbors, according to a citizen living nearby
