A Vietnamese woman has been sentenced to 14 years in prison for causing the death of her own father when a conspiracy to harm his mistress went awry.

The People’s Court in the Mekong Delta province of Hau Giang announced the punishment for Tran Kieu Trang, 47, who resides in Ho Chi Minh City, at the conclusion of her trial on Wednesday.

Trang was found responsible for the death of Tran Van Ri, 74, her father, and for inflicting serious injuries on Vo Thi Chien, 43.

Trang was mandated to pay Chien VND2.3 billion (US$98,476) as compensation.

According to the indictment, Ri owned a trade and production company in Ho Chi Minh City and had developed a romantic relationship with Chien, who was his deputy director.

Trang’s statements showed that her father had handed over the firm’s management to Chien and paid little attention to the family.

The woman started plotting to separate the couple in March 2017, when she asked Nguyen Thi The to arrange an attack on Chien in exchange for VND250 million ($10,702).

Four months later, The hired Nguyen Anh Tuan, Nguyen Quoc Huy, Nguyen Huu Loc, and Pham Thanh Toan for the job.

The gang attempted to assault Chien in late September 2017 but failed.

They managed to talk Cai Van Chung, Ri’s personal driver, into working with them and planned an attack on October 4, when Chung was taking both Ri and Chien from Ho Chi Minh City to the Mekong Delta region.

At 11:00 pm that day, the group raided the automobile along a section of National Highway 61C in Hau Giang Province.

They blocked the vehicle and forced it to pull over before stabbing Chien in her thighs and stomach with a pair of scissors.

The attackers then poured gasoline on Chien and set her on fire.

While the original target was to only hurt Chien, the entire car caught fire while both Ri and Chien were still inside.

The two victims were then brought to the hospital with severe burns. Ri succumbed to his wounds a few days later.

The incident first appeared to be an attack by a group of muggers but police eventually uncovered the conspiracy.

Aside from Trang, The, Tuan, Huy, Loc, Toan, and Chung, aged from 25 to 57, were also put behind bars for seven to 20 years for murder.
