Demjanjuk's attorney questions evidence

(AP) — John Demjanjuk's defense lawyer is questioning the validity of evidence presented by a top German investigator, including an identity card that allegedly shows his client was a death camp guard at Sobibor.

Attorney Ulrich Busch said in court Wednesday that he has seen "conflicting" examples of the ID card and asked investigator Thomas Walther how the original came into the hands of the United States Department of Justice.

Walther says he doesn't know.

Walther, now retired, led the investigation that prompted Germany to prosecute Demjanjuk on 27,900 counts of being an accessory to murder on allegations he was a Sobibor guard. Demjanjuk denies having ever been at the camp and has maintained the ID card could be a fake.
