Police are investigating the mysterious deaths of three Northvolt employees who passed away within the last six months after work shifts.

A 33-year-old man, a 19-year-old man, and a man in his 60s were found dead in their homes in Skellefteå.

The forensic investigation has yet to determine the cause of death, and authorities have not ruled out the possibility of toxic exposure.

The police are conducting extensive interviews to gather more information, while many theories and tips continue to flood in.

The investigation is expected to extend into the fall.
