Question: Tell us all you know about the experiments on human beings performed in
Detachment 100.

Answer: Experiments on human beings were performed in August-September 1944. These
experiments took the form of giving the experimentees, without their knowledge, soporific
drugs and poisons. The experimentees included 7-8 Russians and Chinese. Korean bindweed,
heroin and castor-oil seed were among the poisons used in the experiments. These poisons
were put in the food.

The poisoned food was given to the experimentees five or six times over a period of two
weeks. Korean bindweed was used mostly in soups, I think heroin in porridge, while tobacco
was mixed with heroin and bactal. After eating the soup mixed with Korean bindweed the
experimentees dropped off into a deep five-hour sleep 30 minutes or an hour later. After two
weeks the experimentees were so weak that they could no longer be used.

Question: What happened to them then?

Answer: For purposes of secrecy all the experimentees were put to death.

Question: How?

researcher, was put to death with an injection of one-tenth of a gram of potassium cyanide.

Question: What did you do with the body of the Russian, whom you had killed?

Answer: I dissected the body at the detachment's cattle cemetery.
