Alokaab Saleh Muhammed, third secretary at the Kuwaiti Embassy in Moscow, was found dead next to a railway line. In spite of being only 30 years old, he allegedly died of heart failure.

Investigators were intrigued by the fact that he was carrying no papers, which slowed down the body identification process.

Nor could they find any trace of the 100 000 US dollars that he had stashed in his Porsche 911 Carrera S.
