A young sports coach had already been dead for an hour when text messages were sent to her concerned father, suggesting she was in trouble.
Single noted Lilie was happily interacting with Thijssen before her death and appeared to have no indication of what he would do.
“No matter how many times you see that footage, it is not easy to watch,” she said as her voice broke.
Security footage from earlier in the evening showed Thijssen alternating which hand held the hammer while practising the murder outside the bathroom.
He was observed deactivating the automatic sliding doors, which Single explained was to keep the school cleaners from interrupting his assault on Lilie.
In addition to investigating the events leading to the deaths of Lilie and Thijssen, the inquiry will look into coercive control and inappropriate conduct in relationships, aiming to avoid future tragedies.
