A life sentence has been handed down to a woman who murdered a four-year-old boy and his grandmother after her ex-lover refused to continue a relationship with her.

Gagging and binding her former lover, Brian Mach, in his Melbourne home, Cai Xia Liao then proceeded to stab his grandson, Alistair Kwong in his bed.  The boy was staying at his grandparents home for a sleepover.

Cai Xia then hid within the home for a further ten hours, before attacking the boy’s grandmother Mai Mach as she returned home from work.  Mai suffered more than 23 stab wounds inflicted by Cai Xia in the back garden.

In sentencing, Justice Lex Lasry described Cai Xia’s actions as “a crime that is horrendous and unbelievable”.  He explained further;

“The killing of a child is extremely serious. Your actions were extreme, grave and callous.This murder falls into the worse category.”

Brian and Cai Xia had been in a relationship for three years, in which Brian was separated from his wife.  Brian re-established his relationship with his wife and ended the relationship with Cai Xia.  Cai Xia had wanted the relationship to continue.

Judge Lasry accepted the murder of Ms Mach was premeditated and also accepted she had a  personality disorder.  

Cai Xia was sentenced to life for the two murders and will serve a minimum of 32 years in jail before being eligible for parole.

  • She should never be released how evil can someone be to wait for 10 hrs with the body of a child. A very sick, evil & sad woman.


  • How someone can do such an evil thing to anyone let alone an innocent child :-(


  • I would have given her life never to be released. Even so, no matter what the sentence, it will never bring back the lives of the two innocent victims.
