A half-burned U.S. passport was found near the body of a man who had been murdered in an abandoned garage in the Ural mountains city of Yekaterinburg, police said.
The body showed signs of foul play, and police believe the man died from a stab wound to his neck and traumatic brain injuries, RIA-Novosti reported. The man was also found handcuffed.
It is unclear if the passport belonged to the victim, since the photo in the passport was burned.
Police have opened a criminal investigation and the U.S. Consulate General in Yekaterinburg has been notified.
