An Israeli foreign ministry source said: "The doubt isn't over whether he was Israeli, it's not quite clear what his name is. We do not know what he has been involved in. Usually in the event of the death of an Israeli citizen abroad, we are asked to inform the family. But in this case we believe the close family is residing in Britain, maybe in the London area." Detectives in London believe the victim was linked to criminal activity, probably international drugs networks. While they do not believe he was a major player, Yunataev went to great lengths to conceal his identity.
