It is NWT that first wrote about the police theory.
Police suspect that the 43-year-old has been murdered.
On May 20, a preliminary investigation into suspected kidnapping was launched and later the case was reclassified as murder.
A woman and a man are reasonably suspected, the lower degree of suspicion, of kidnapping.
They are already in custody for theft in another case.
The prosecutor is now awaiting the National Board of Forensic Medicine's assessment and hopes that an identification of the man will be completed as soon as possible.
