CHINESE WOMAN KILLS EX LOVER, HIS WIFE AND GRANDSON!

A spurned Chinese woman sobbed hysterically in court on Thursday after being accused of killing a four-year-old boy in Australia with garden shears before laying in wait for his grandmother and stabbing her to death.

Cai Xia Liao, 45, had been having an affair with the boy's Melbourne-based grandfather Brian Mach, 61, until he recently called it off, prompting her to allegedly tie and gag him after arriving at his home on Tuesday morning.

Police claim she then killed his grandson Alistair Mach, 4, whom he was babysitting, as the boy lay in bed, stabbing or slashing him with the shears in the head and neck. He also had deep defensive wounds to his fingers, hands and arms.

Cai, in Australia on a tourist visa, is accused of waiting 10 hours for Mach's wife Mai to return home before allegedly attacking and murdering her with the same shears, stabbing or slashing her 23 times in the backyard.

A neighbour alerted police after witnessing the second killing.

An out-of-sessions court hearing late Wednesday was told Brian Mach had recently broken off a relationship with the woman. He was taken to hospital with minor injuries, police said.
