A taekwondo instructor has admitted to killing a couple and a child in a shocking triple murder before he attempted to claim he had been attacked in a random incident.

A taekwondo instructor has admitted to a shocking triple murder in Sydney’s west in which he killed a couple and a seven-year-old child.

Kwang Kyung Yoo on Thursday pleaded guilty to three counts of murder when he appeared in the Parramatta Local Court.

He admitted to murdering Min Cho, 41, and a seven-year-old child at a North Parramatta taekwondo studio, as well as Ms Cho’s husband, Steven Cho, 39, at a Baulkham Hills home on February 19 last year.

The North Kellyville man has been in custody since he was arrested in hospital and will now face sentencing proceedings in the NSW Supreme Court.

Ms Cho and the child were killed inside the taekwondo studio where the boy was a student.

Yoo, who was known to his students as Master Lion, left the bodies inside the studio before driving Ms Cho’s white BMW to her Baulkham Hills home, where Mr Cho was stabbed several times.

NSW Police found Mr Cho’s body at the Watkins Rd, Baulkham Hills address before the bodies of his wife and the child were discovered by police two hours later.

Yoo drove to Westmead Hospital with stab wounds to his chest, arms and stomach and claimed he was randomly attacked in a Woolworths carpark.

However he sustained the injuries while stabbing Mr Cho to death.

He will now appear in the Supreme Court in August before he is sentenced at a later date.
