Taekwondo instructor accused of triple murder in western Sydney faces delay in entering plea

A taekwondo expert is accused of violently killing an entire family, including a seven-year-old boy, at two separate locations.

A martial arts instructor accused of violently killing an entire family in Sydney’s west faces a fresh delay in fronting court for the triple murder charges.

Kwang Kyung Yoo, 50, was charged with the murders of Min Cho, 41, and a seven-year-old boy at North Parramatta as well as the murder of Ms Cho’s husband, Steven, 39, at a Baulkham Hills unit block in February 2024.

Police allege that Ms Cho and the child were in February murdered inside a North Parramatta taekwondo studio where the boy was a student.

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

Mr Yoo’s solicitor appeared in Parramatta Local Court on Thursday in front of magistrate Kate Thompson.

The lawyer requested a six-week adjournment of Mr Yoo’s case after “discreet questions” came up in a report obtained by a psychologist.

A further case conference is scheduled for May 28. It will determine the accused’s plea and identify any disputed facts.

A case conference was previously held between the prosecution and Mr Yoo’s defence in October.

The North Kellyville man has been in custody on remand since his arrest in Westmead hospital last year.

At the time, he was hospitalised for injuries, including stab or slash wounds to his chest, arms and stomach, police said.

Mr Yoo claimed he sustained the injuries after being attacked in a North Parramatta carpark. Police allege Mr Yoo received the injuries while he stabbed Mr Cho to death.

Mr Yoo is due to appear at Parramatta Local Court on May 1.
