Relatives of convicted Nazi war criminal John Demjanjuk claimed, Thursday, that Demjanjuk was put to death through drugs at the senior citizen center where he lived out his last days. They have submitted a claim to German authorities.

Demjanjuk's son said, Wednesday, that his father was given an overdose of a pain killer banned in the United States. The manufacturer warned against the drug being ingested to the patient's bone marrow. He demanded an investigation.
