Jürgen Bartsch (born Karl-Heinz Sadrozinski; November 6, 1946 – April 28, 1976) was a West German serial killer who murdered four boys aged between 8 and 13 and attempted to kill a fifteen year old boy. The case of this sexual offender was the first in German jurisdiction history to include psycho-social factors of the defendant, who came from a violent early surrounding, to set down the degree of penalty. Early life Bartsch was born an illegitimate child whose birth mother died of tuberculosis five months after his birth, and so he spent the first months of his life being cared for by nurses. At 11 months he was adopted by a butcher and his wife in Langenberg (today Velbert-Langenberg), who gave him the name Jürgen Bartsch. Bartsch's adoptive mother, who suffered from obsessive-compulsive disorder, was fixated on cleanliness. He was not permitted to play with other children, lest he become dirty. This continued into adulthood; his mother personally bathed him until he was 19. At the age of 10, Bartsch entered school. Because, in his parents' opinion, it was not sufficiently strict, he was moved to a Catholic boarding school. Bartsch was physically abused as a baby and was often discovered with visible scars and bruises. His mother also physically beat him, often in the same room where his father, the butcher, cut up carcasses. He was detained in an underground cellar for six years and was also sexually abused by his mother during bathing sessions. Bartsch was sexually abused by his thirteen-year old cousin when he was only eight years old and was also later abused by his teacher when he was thirteen years old. Murders Bartsch began killing at the age of fifteen. His first victim was Klaus Jung who was murdered in 1962. His next victim was Peter Fuchs who was killed three years later in 1965. He persuaded all of his victims to accompany him into an abandoned air-raid shelter, where he forced them to undress and then sexually abused them. He dismembered his first four victims. His intended fifth victim, 15-year-old Peter Frese, however, escaped by burning through his bindings with a candle that Bartsch had left burning after leaving the shelter that he has been keeping his victims in. Bartsch was arrested in 1966. Sentence Upon arrest, Bartsch openly confessed to his crimes. He was sentenced to life imprisonment on December 15, 1967,
