Jürgen Bartsch (born Karl-Heinz Sadrozinski) (November 6, 1946 – April 28, 1976) was a German serial killer who murdered four boys aged between 8 and 13 and attempted to kill another.
The case of the sexual offender Bartsch in German jurisdiction history was the first to include psycho-social factors of the defendant, who came from a violent early surrounding, to set down the degree of penalty.
