Paul Thijssen, the man who brutally killed Lilie James and stashed her body in their school gym bathroom, ended his own life after his vile plan unraveled. The 24-year-old likely panicked as he realized he had lost control of the situation following the murder. Criminal psychologist Tim Watson-Munro suggests that Thijssen's decision to take his own life indicates his awareness of the consequences of his actions, rather than any signs of mental illness.
Thijssen, a former student of St Andrew's Cathedral School and a hockey coach, carried out the most shocking stages of his plan, which involved luring Lilie to the gymnasium under the pretense of returning sports equipment. Dr. Watson-Munro explains that individuals with controlling and toxic traits like Thijssen struggle with rejection and become more aggressive when they lose control of their victims. The psychologist also highlights that Lilie, described as a gentle and kind person, may not have realized the danger she was in when she innocently met up with Thijssen.
Even after killing Lilie, Thijssen continued to exert control by posing as her and using her mobile phone to send messages to her father. He then drove to Diamond Bay Reserve in Sydney where he spent hours wreaking havoc and contemplating his future. Thijssen eventually called the police to inform them of Lilie's body in the gym bathroom before ending his own life by jumping from the cliffs above Diamond Bay.
Despite the tragedy, Thijssen's parents have made the decision to have his remains cremated and scattered in Australia. The investigation into these horrifying events continues, but for Lilie's loved ones, they are left to mourn the loss of a sweet and kind young woman who fell prey to a controlling and dangerous individual.
