Breakthrough in Lilie James murder investigation as police outline chilling ... trends now
Paul Thijssen bought a hammer and arranged to borrow a car just hours before Lilie James was brutally murdered - as his twisted plot to kill and a Triple Zero call are revealed.
Police now believe the murder of Ms James, 21, was not a crime of passion but a planned and premediated attack that came just days after she ended her brief five-week romance with 24-year-old Thijssen.
The budding water polo coach was bashed to death in a gym bathroom inside St Andrews Cathedral School just after 7pm last Wednesday.
Thijssen, a former student of the elite Sydney school, was captured on CCTV footage purchasing a hammer at a hardware store in the city's east, not far from his Kensington home, on the morning of the attack.
It's understood the hammer was not the one used to kill Ms James. Police believe Thijssen had two hammers, one of which may have come from a school storeroom.
Thijssen drove a borrowed 2003 Lexas sedan to work on the day Ms James died, with a source close to the investigation telling the Daily Telegraph that the car would have allowed the sports co-ordinator to 'get away quickly afterwards'.
He also called police four hours after Ms James was killed inside the gym bathroom, with cops receiving an urgent dispatch call from triple zero.
'Informant says there is a body in a bathroom on the right-hand side in reception area. Through reception and to the left. Informant says he was there a couple of hours ago. Female body,' the operator stated.
It comes as exclusive Daily Mail Australia photos reveal the inside of Thijssen's house just hours after he is believed to have murdered Ms James.
Paul Thijssen's bedroom, hours after he murdered Lilie James, contained a Dutch 'Stag' brand hockey shirt on top of a rolled-up doona, tablets including paracetamol and Nurofen and a men' shaver on the bed. Thijssen moved into the house in August
Photos of his messy bedroom show a pile of pills, a broken cupboard, a half-used toilet roll and clothes strewn across the floor.
Thijssen moved into the cramped semi-detached in Kensington in southeastern Sydney in August with a young female flatmate and a fellow male hockey player.
Neighbours said the three flatmates were courteous but 'kept to themselves' and weren't aware of Thijssen's identity until the horrific events of October 25.
Thijssen, a former St Andrews school graduate who grew up in the Netherlands, had been living in nearby Zetland before moving to the Kensington house.
His last known address before he did the unthinkable looked hastily abandoned following the tragedy.
A rolled-up doona, green and yellow shirt by Dutch hockey label Stag, packets of Panadol, Nurofen and Strepsils, an electric shaver, personal items in storage trays including sunglasses, a wrist-sized sweatband and a multi-task tool were dumped on the bed in the middle bedroom that was believed to have been occupied by Thijssen.
A bottle of air freshener sat propped above his bed and clothes were strewn around the room which also contained a flat-screen TV and white wardrobe with a broken door.
