Searching for evidence using ROV
On the night of August 11th, a serious crime occurred in Trondheim. Three men in their 20s were charged and held in custody for attempted murder after a stabbing incident. As part of the ongoing investigation, the police are looking for a weapon suspected to be linked to the crime.
We search for objects with an underwater drone.

Trondheim Police used the Blueye ROV for this critical search. On the morning of August 20th, they confirmed that they had located a knife that could be related to the crime, which has since been sent for forensic investigation.
Human remains discovered by Researchers in Savalen Lake
Researchers from the Norwegian Institute for Nature Research (NINA), Johanna Järnegren and Silje Margrethe Nessjø Larsen, made a startling discovery a month ago while mapping fish spawning areas for char at Savalen Lake in Norway using the Blueye X3 ROV. Initially mistaking the sight for debris, they were shocked to find a raincoat and rubber boots containing bone fragments on the lakebed.
This find has stirred memories in the local community, particularly for 84-year-old Jarle Tronslien, who recalled a tragic incident in 1957 when a married couple from Oslo drowned in the lake. Despite efforts, only the woman's body was recovered at the time.
I immediately thought of the drowned couple. It is quite possible to believe that it could be that person, but I don't know.
- Jarle Tronslien as told to VG News.
The Blueye X3 ROV used for research was equipped with laser and Subsonos tag for precise positioning and size measurement of the find. Police are now involved, and the remains have been sent to the Forensic Institute for identification. The researchers hope this discovery can bring clarity and answers to the families involved.
Blueye X3 - A vital tool for underwater investigations
Using ROVs provides search and rescue teams with essential visibility beneath the surface, making them invaluable for more complex missions. The Blueye X3, equipped with sonars, enhances the ability to locate and track objects in murky or deep waters, where visibility is often limited. There are different sonars that can be integrated with the X3 ROV. You can read about it here.
