A Chinese woman who stabbed her ex-partner’s wife and grandson to death has been sentenced to a minimum of 32 years in prison.

When Mrs Mach returned home from work she then stabbed her to death too.

Ms Liao was today sentenced to life imprisonment, with a minimum of 32 years in the Victorian Supreme Court.
