Tragic final moments of Lilie James revealed at inquest

The final moments of Lilie James, a beloved 21-year-old water polo coach, were captured on CCTV just minutes before she was brutally murdered by her ex-partner, Paul Thijssen, inside a Sydney school. Shocking new details have emerged during a coronial inquest into the October 25, 2023, killing, revealing the calculated planning behind the horrific crime that shook the nation.

Lilie was viciously attacked with a hammer in a bathroom at St Andrew’s Cathedral School in Sydney’s CBD. The inquest heard that Thijssen, 24, a fellow teacher at the school and Lilie's former boyfriend, meticulously stalked her and rehearsed the attack in the days leading up to her murder.

Court proceedings detailed how Thijssen, a Dutch national, spent days stalking Lilie, watching her movements and even performing dry runs of the attack. CCTV footage played at the inquest showed him practising how to burst into the bathroom where he would ultimately kill Lilie. The court heard that he placed a “cleaning in progress” sign outside a different bathroom to manipulate her into using the one where he planned the attack.

On the evening of October 25, Lilie was seen on CCTV chatting with Thijssen as she walked to the bathroom. Moments later, footage captured him switching a hammer to his right hand before charging inside at 7:14pm. While the attack itself was not recorded, Thijssen was seen lingering outside, seemingly listening to the aftermath, before locking the bathroom door to prevent entry. He remained inside for an hour and 12 minutes before leaving.

After the murder, Thijssen took Lilie's phone and sent messages to her father, Jamie, pretending to be her.

“Don’t ask why or call please come to the school now and pick me up,” he texted. When Mr James responded with concern, Thijssen continued the deception, replying, “All good just came (sic) trouble.”

In a chilling turn, Thijssen later made a triple-0 call after driving to Diamond Bay Reserve in Vaucluse. Described by the operator as eerily calm, he reported the location of Lilie's body before refusing to disclose his identity. He ended the call with an unsettling message: “I think someone should just go in there before people arrive in the morning. Thank you.”

At 11:59pm, CCTV captured Thijssen entering the reserve, where he later took his own life by jumping from a cliff. His body was discovered in the water 32 hours later.

Police found Lilie's body around the same time they began searching for Thijssen. Due to the sheer amount of blood in her hair, officers initially mistook her for someone else, leading to early misinterpretations of the crime scene. A post-mortem examination later confirmed she had suffered at least 25 blows to the head and neck.

The inquest also heard that Thijssen had a history of stalking behaviour, having previously followed another ex-girlfriend. Additionally, he had forged documents in an attempt to extend his Australian working holiday visa.

Investigations revealed that in the six days leading up to Lilie's murder, he had driven to her house multiple times in a hired car, taken photographs of vehicles parked outside and tracked her movements. Further footage showed him buying a hammer and duct tape from a hardware store, though that hammer was later found unused in a school storeroom.

The brutal murder of Lilie James has left the community reeling. St Andrew’s Cathedral School was closed for two days following the tragedy, and the inquest continues before Coroner Teresa O’Sullivan, seeking to provide further insights into how such a devastating crime unfolded.
