Police investigators in Russia’s Kaliningrad region on Monday discovered the decapitated body of the CEO of a local fertilizer company.

The chief executive, Alexei Sinitsyn, is believed to have died by suicide, according to a law enforcement source cited by the Vedomosti business newspaper.

Investigators told state news agencies that Sinitsyn’s body was found with an attached towing cable under a bridge outside the city of Kaliningrad. They said they were establishing the circumstances of his death.

Sinitsyn, 43, was the CEO of K-Potash Service, which has been developing the Nivensky-1 potassium-magnesium deposit in Kaliningrad since 2014. The ambitious project was originally planned to be launched in 2021, but has since been pushed back to 2032.
