U međuvremenu, njemačke vlasti su našle tragove polonijuma 210 na nekoliko lokacija koje je posjetio Kovtun -- u stanu njegove bivše supruge, u automobilu koji je koristio, te u kući njegove svekrve.
Meanwhile, German authorities have found traces of polonium 210 in several locations visited by Kovtun -- the flat of his ex-wife, in a car he used, and at his mother-in-law's home.
