Woman steals sister's boyfriend but later buries him alive so she can be with new lover

China: After a brief affair, she convinced him to leave her heartbroken sister and marry her instead - but within a year had moved on to another lover.

 A woman married her sister’s f boyfriend- then stabbed him and buried him alive so she could be with a new lover.

Twisted Qiao Li Tsui, 25, first met Jian Tsao, 30, two years ago when he was engaged to her sister.

After a brief affair, Qiao convinced him to leave heartbroken sister Wan Niu, 27, and marry her instead.

But a year after the wedding in Hangzhou, a city in eastern China, she met new lover Cai Chen, 27, online and began having an affair with him.

The demented couple then hatched their plot to get rid of Qiao’s husband so they could marry.

Luring him into the mountains on the pretence of having a picnic, she then attacked unsuspecting Jian, knifing him repeatedly in the chest until he fell unconscious.

She and her lover, who was waiting nearby, then dug a shallow grave and threw the unconscious body into it before burying him alive.

The pair were caught three days later, when a guilt-ridden Cai handed himself into police.

After Cai showed them where they had buried Jian, his body was dug up and sent for an autopsy.

An examination revealed there was dirt and soil in his lungs, indicating he was still breathing when he was buried.

The woman’s sister, Wan, said: "She is an evil, conniving bitch who deserves to be shot.

"She ruined my happiness, destroyed my fiance, and has now destroyed the life of this new lover.

"She has no remorse and no feelings. I hope she rots in hell."

A police spokesman said: "This is one of the most diabolical love crimes we have ever come across."
