St Andrew’s Cathedral School: Read principal’s powerful letter to parents about the ‘horror and evil’ at the school where 21-year-old Lilie James was killed in the gym toilet – as suspected killer’s concerning Facebook posts emerge

EXCLUSIVE 

The principal of the school where 21-year-old sports assistant Lilie James was found murdered has penned a powerful letter to parents condemning the ‘horror and evil’ that occurred on its grounds.

It comes Facebook posts emerged that shed light on her suspected killer Paul Thijssen’s alarming behaviour as the Netherlands-born 24-year-old sought an Australian visa. 

Ms James was found beaten to death in a gym bathroom at St Andrew’s Cathedral School just before midnight on Wednesday. 

Police suspect her ex-boyfriend and colleague Thijssen, 24, killed her after she broke off their brief, secret relationship before driving to the cliffs at Vaucluse.

Tradesman spotted a body in the water at the base of the cliff about 8am on Friday. It was retrieved around midday. It is yet to be formally identified. 

As the St Andrew’s community comes to terms with the tragedy, Principal Julie McGonigle sent a letter to parents on Friday vowing to support the James and Thijssen families, and that it would not ‘define’ the community. 

Paul Thijssen, a Netherlands-born former student at the school, is suspected of killing her after she ended their brief relationship 

She wrote: ‘We are deeply concerned for the families directly involved in this incident and I am personally committed to aligning our communications with what is respectful to them and in lock step with the NSW Police.

‘I will not move at a pace that ignores those priorities.

‘Thank you sincerely for the love and support you are generously giving at this time – as I will share with staff today – the horrors of evil, do not and will not define our community, that is my oath. 

‘Thank you for partnering with me in that commitment.’

The school has closed for two days, with the exception of students sitting exams. The gym remains a crime scene. 

Dr McGonigle’s powerful statement comes as Facebook posts emerge showing Thijssen bragging about relentlessly hassling Australian authorities every single day  for a working holiday visa.

In December 2021, the hockey coach, who is originally from the Netherlands, revealed he had successfully secured a visa in Australia after bombarding the Federal government with daily emails.

‘Hi all, I just want to spread some good news,’ he wrote in a group dedicated to foreigners living Down Under. 

‘I applied from Europe for my 2nd 417 WHV last Monday, and got it granted today.

‘I emailed the working holiday department every day after I applied, and my guess is that maybe this might’ve actually helped.

Thijssen bragged about being pushy with Australian authorities while trying to get a working holiday visa approved in 2021

‘Just want to give you some encouragement to keep on hoping, they’re definitely approving new applications now!’ 

While some commenters asked for advice on what to write, another said she thought it was ‘funny’ Thijssen contacted authorities so persistently. 

Lilie James’s family breaks their silence 

As the school community mourns the beloved water polo coach, Ms James’ grieving family broke their silence to pay tribute to their ‘vibrant’ daughter. 

‘We are devastated and heartbroken by the loss of our beautiful Lilie James,’ they said in a statement. 

‘She was vibrant, outgoing and very much loved by her friends and family.

‘We are tremendously grateful for the support of the community at this difficult time.’

A source close to the family told Daily Mail Australia everyone in Ms James’ circle is ‘completely numb’. 

‘It’s numbing – there are no other words that can describe the pain we’re in,’ they said.

‘Everyone is completely numb.’

Workers at a construction site in Vaucluse called police about 8am on Friday after making the grisly discovery, close to Diamond Bay Reserve, where officers had earlier been searching for Thijssen. 

Ms James was reported missing to police when she failed to return to her family’s Kogarah Bay home, in Sydney’s south, on Wednesday night. She was later found beaten with a hammer. 

Thijssen, who she had been in a secret relationship with for just weeks, later rang Triple Zero and told operators there was a body in the school’s gymnasium they should investigate. Some of his possessions were found at the cliffside. 

Authorities spent Friday morning working to retrieve the body from the water, with a Westpac rescue helicopter and a police jetski.

The body, which appeared to be naked, battered and bloated, could be seen slumped between rocks at the base of the cliff. 

While Ms James’s family and friends try to come to terms with their ‘everlasting grief’, police are desperately trying to piece together the events of the tragic night. 

Superintendent Martin Fileman said officers were presented with a ‘confronting’ scene when they arrived at the school due to the severity of her injuries.

A post-mortem examination will be conducted to establish the cause of death.

Detectives are talking to witnesses and also combing CCTV from the school to piece together what led to the killing.

Mr Thijssen graduated from the school in 2017 and worked there as an assistant sports coach, according to his Linkedin profile. 

Ms James was studying sports business at the University of Technology, having graduated from Danebank Anglican School in 2020, while coaching at St Andrew’s part-time.

Supt Fileman said the circumstances of the death would also be confronting for students as it involved school staff.

‘We’re currently working in with the school to ensure the welfare of the students and they have measures in place to make sure those students are taken care of,’ he said.

Meanwhile, tributes have poured in online for the talented young dancer, actor and swimmer whose life was tragically cut short.

‘There was nothing you couldn’t do, beautiful girl. Fly high Lil, we will miss you forever,’ one friend said. 

‘Lilie was the most kind, caring, funny and supportive friend there is,’ another friend wrote.

‘I could never think that we would lose our friend in these circumstances. Our world is so cruel. Thank you for the memories and the good times Lilie.’
