Alleged murderer Kwang Kyung Yoo ‘falsified records’ describing him as a distinguished professor

The taekwondo instructor who is expected to be charged with the murder of three people falsified his academic qualifications and taekwondo experience.

The man at the centre of an alleged triple murder falsified his university qualifications and taekwondo experience it can be revealed.

Kwang Kyung Yoo, known by his students as Master Lion, is set to be charged with murder after he is alleged to have fatally strangled 41-year-old Min Cho and a seven-year-old child inside his taekwondo studio before fatally stabbing 39-year-old husband Steven Cho.

Mr Yoo’s Facebook page describes him as a senior professor at Macquarie Uni.

However a spokesperson for Macquarie University told news.com.au there was no record of him in the uni’s current and past database.

Mr Yoo also proudly posted on social media a document supporting his bid for an even higher position - Distinguished Senior Professor.

But the spokesperson said the role doesn’t actually exist and it “isn’t a title that we use”.

He also boasted on his website he is currently studying a PhD in sports science at the University of Sydney.

But the university told news.com.au they have “no record of that individual being a student or graduate.”

Mr Yoo’s lies go beyond his academic record.

He also claimed on his martial arts academy website to have competed at the 2000 Sydney Olympics, something which was flatly denied by Australian taekwondo.

It comes as troubling new details come to light of the forty-nine-year-old including that he has a family of his own.

His distraught wife is understood to have repeatedly called him for answers after he was admitted to hospital. She is not accused of any wrongdoing.

In videos posted to Facebook, Mr Yoo can be seen filming his wife, son and small dog as the family walk their Kellyville neighbourhood and play soccer in the local park.

“Having a precious time with my treasures on [this] beautiful Sunday afternoon,” he captioned one video.

In another video, Mr Yoo can be seen sparring with his then-six-year-old son in 2022.

“Having a most great time with my Son. My Son was asking me for a little training today.”

Mr Yoo underwent surgery overnight after admitting himself to hospital with “slash wounds” to his chest, arms and stomach on Monday night, telling police he was attacked in a shopping centre car park in Parramatta, police say.

Meanwhile students at Mr Yoo’s prominent martial arts academy in North Parramatta have been left bewildered by the alleged triple murder.

A parent who didn’t want to be named told news.com.au the community has been “saddened and completely shocked” by what happened.

“We trusted him with our children,” the parent said.

“We watched and observed him. He was a very nice person. All of the community would think he would never do such a thing.”

The parent said Ms Cho often watched her child as he practised at the academy and was popular with other Korean mums who congregated there.

Another parent said they were sent a “weird text” by the academy on Tuesday morning informing them lessons were cancelled because the academy’s chief instructor, Master Yoo, was in hospital.

The cryptic message announced that “pick-up at 3:10pm for afterschool activities is no longer possible”.

“Due to injuries resulting from a car accident this morning Master is currently in the hospital,” the text read.

One mother said it was “clearly not a car accident when I saw all the police outside the studio when I went to pick up the kids from school”.

Tributes continue to pour in for the victims.

Steven Cho’s boss described his “shock and sadness” at the news in an email to staff, according to the Sydney Morning Herald.

A close colleague at Richard Crookes Constructions described him as “a very outgoing young man wrapped up in his work as a mid-tier executive”.

“I have never met a more normal enthusiastic guy in the work environment,” the colleague enthused.

Mr Cho was referred to as “the machine” because he was so good at his job as a senior estimator at Richard Crookes Constructions, where he had worked for about two decades.
