Alleged triple murderer forged documents

The man allegedly behind a triple homicide in Sydney’s west forged his university qualifications and lied about his Olympic taekwondo achievements, it has been revealed.

Kwang Kyung Yoo, a 49-year-old taekwondo instructor, has been charged with three murders of 41-year-old Min Cho and a seven-year-old child at his Paramatta north martial arts studio.

He has also been charged with murdering the woman’s husband, 39-year-old Steven Chu, by stabbing him at his home in Baulkham Hill on Monday.

Mr Yoo allegedly drove to Westmead Hospital with stab wounds to his chest, arms and stomach, and claimed he was randomly attacked in a supermarket car park.

But police will allege he sustained the injuries while committing murder.

Mr Yoo claims to be a Senior Professor at Macquarie University on his Facebook page and reportedly posted a photo to social media indicating he was applying to be awarded with a more senior position within the university, a “Distinguished Senior Professor”.

But a spokesperson for Macquarie University said “there is no record of any appointment of Kwang Kyung Yoo, nor Lion Yoo, to a position at Macquarie University”.

While a “Distinguished Professor” is a title given out by the Sydney university “Distinguished Senior Professor” is not.

On the website for Mr Yoo’s business, Lion’s taekwondo and Martial Art Academy, he suggests he is currently studying a PhD in Sports Science at the University of Sydney.

But the university said they had “no record” of Mr Yoo being a “student or graduate”, according to The Daily Telegraph.

Mr Yoo also claims to have won a silver medal in the 2004 Taekwondo World Cup, a gold in the 2002 Martial Arts World Championships and a gold medal in the 1995 Army Taekwondo Championship.

But it can be revealed that none of the three events exist by those names and there appears to be no record of Yoo taking home a medal at any of the competitions.

Mr Yoo also claims he was selected by Australia to compete in the 2000 Olympics, but Australian Taekwondo denied the claims, according to The Daily Telegraph.

Neighbours of the Cho family told NCA NewsWire they were “shocked” and “scared” by the alleged murders.

Baulkham Hills resident Saniu Awais, whose house looks directly at the Cho family house, said she didn’t hear or see anything on Monday night when Mr Cho was allegedly murdered.

“That’s what’s so shocking. How did he get here?” she said, noting that the neighbourhood was known for being “very safe”.

Ms Awais said she had “never heard of this” happening in the area during the nearly four years she has lived there.

“It’s very sad and shocking,” she said.

“(The neighbours) all want a kind of closure. We all want to know what happened. Because otherwise you’re just scared for your kids.”
