The 24-year-old — who is James’ ex-boyfriend, colleague and suspected killer – is seen arriving at Diamond Bay Reserve in Vaucluse, about 11km from the city, just before 9pm on Wednesday.
The video shows Thijssen, who worked as a sports assistant at the school, walking up and down a path, and getting back into his car before it is understood he called triple-0 at about 11pm to notify police about James’ body at the school.
Following a search, a body was located on rocks at the base of nearby cliffs on Friday morning.
The body was retrieved shortly after midday, NSW Police said.
It has not been confirmed as belonging to the 24-year-old, with formal identification yet to take place.
However, detectives have previously said they were looking at the possibility Thijssen had taken his own life.
The discovery comes about 24 hours after police announced they were looking for Thijssen in relation to James’ death.
“From her injuries, it was apparent she was a victim of a homicide,” Sydney City Police Area Commander Superintendent Martin Fileman said, adding that she had suffered serious head injuries.
“Property associated with the homicide”, including a hammer, was found at a site in Vaucluse on Thursday.
Fileman described the crime scene as “confronting”.
CCTV footage from the school allegedly shows James and Thijssen entering the school bathroom, with Thijssen leaving well over an hour later.
7NEWS understands the pair had been dating but James broke it off a few days ago.
Thijssen is believed to have a long history with St Andrew’s.
His LinkedIn profile says he attended the school as a student from 2015 to 2017, when he was a sports captain and part of the school leadership team.
He then took on a sports assistant role the following year, before attending university in the Netherlands.
7NEWS understands Thijssen was previously a hockey coach at St Vincent’s College in Potts Point and, until Thursday morning, was listed on that school’s website as the hockey coach for it most recent season.
Police investigations continue.
