BERLIN - A doctor leading a group therapy session gave participants drugs and other substances that killed two and left 10 hospitalized, Berlin police said Sunday. One person was left comatose and in critical condition.
The doctor acknowledged dispensing the substances and drugs, said Martin Steltner, a spokesman for the Berlin prosecutor's office, Sunday.
What drugs were used was unclear Sunday. Police said, "the chemical-toxicological investigation will take a while."
The doctor, his wife, who runs an alternative medicine practice, and 12 others attended the session Saturday, police said.
After people got sick, police and ambulances found 12 who appeared to be severely poisoned.
A 59-year-old man died at the scene and a 28-year-old man died that night in the hospital, police said. Nine others were released from the hospital Sunday.
The doctor says he specializes in "depth psychology, bodywork and art therapy, and spiritual crises," according to an Internet Web site.
