The Litvinenko Poisoning Germany Plays Central Role in Polonium Investigation

A passport photo found in a Hamburg city office is proving to be a central piece of evidence in the investigation into the murder of the ex-Russian spy Alexander Litvinenko. It shows that Dmitry Kovtun, a suspect who met with Litvinenko on the day police believe he was poisoned, came into contact with Polonium 210 at least two days earlier.
