Jürgen Bartsch (born Karl-Heinz Sadrozinski; 6 November 1946 – 28 April 1976) was a West German serial killer and sex offender who murdered four boys aged between 8 and 13 and attempted to kill a fifteen-year-old boy. His conviction was the first in German history to include the psycho-social background of the defendant, who grew up in a violent environment, to set down the sentence.
