High-ranking NATO official Yves Chandelon, whose body was found in his car in the Belgian town of Andenne on December 16, killed himself, the chief prosecutor in charge of the case told POLITICO.

Chandelon, a 62-year-old Liege native, was auditor general at the NATO Support and Procurement Agency (NPSA), charged with logistics for the alliance's headquarters in Capellen, Luxembourg. He may have also been involved in probing terrorism financing and money laundering, according to media reports.

"Mr. Chandelon was responsible for executing the NSPA audit programme of work only, which focused solely on NSPA responsibilities, and did not include any activity associated specifically with counter terrorism, or money laundering,” a NATO official said on Wednesday.

Chandelon's body was found near the town of Andenne in Belgium's Ardennes region, some 140 kilometers from his office and 100 kilometers away from his residence in the town of Tournai.

Local media reported that Chandelon's family initially dismissed investigators' view the death was a suicide, believing it was suspicious. The prosecutor's office said some members of the family subsequently changed their minds when investigators found a one-page, handwritten note in the car.

"We cannot go into details on the content of the note but we can say that it is linked to some investments [which had] gone wrong that Mr Chandelon had done with some friends. The family was not aware of these investments," Prosecutor Vincent Mack said. He added that an autopsy had confirmed suicide was the cause of death and a toxicology exam failed to find the presence of any narcotics.

The prosecutor's office will continue to investigate the death and is still conducting a handwriting comparison, though family members have stated they believe it is Chandelon's handwriting on the note.

Chandelon's family could not be reached for comment.

A spokesperson for NSPA confirmed Chandelon had died, but said "out of respect for the family of Mr Chandelon no additional information will be released."
