Just hours after a Russian ambassador was gunned down Monday by a Turkish assassin, another high-ranking Russian diplomat was found shot in the head at his Moscow home, The Mirror reported, citing local media.

Peter Polshikov, 56, was a senior figure in the Latin American department of the Russian foreign ministry, The Sun reported. Some local reports suggest Polshikov may have left the Foreign Ministry and it’s unclear if he worked for the Russian government at the time of his death.

It's unclear when exactly Polshikov died.

Polshikov’s wife was reportedly inside the home at the time of the shooting, but she was said to be safe.

Investigators discovered two bullet shells and a gun under the bathroom sink.

Authorities have yet to offer a theory on how Polshikov died.
