Sture Bergwall

Thomas Quick (born Sture Bergwall 1950 in the parish Korsnäs, Falun, Sweden) is a child molester and serial killer, with over 30 murder confessions (although only eight convictions). He has confessed to committing murder and rape, victimizing mainly men in Sweden and Norway, with the first known murder committed when he was 14. He changed his name after this, and adapted the first name from that of his first victim, Thomas Blomgren, and surname Quick, his mother's maiden name.

According to his own book, Kvarblivelse, he was abused by his father as a child, something which his brother, Sten-Ove Bergwall, denies in the book Min bror Thomas Quick: en berättelse om det ofattbara ("My brother Thomas Quick: A story about the unbelievable.")

He was arrested in 1990 for attempting to rob a bank outside Falun, Sweden. During his years in Säter hospital (receiving treatment for being criminally insane), he started to confess to numerous murders, and he was convicted for eight of them.

Critics of the confessions and the trials claim that Quick never murdered anyone, but that he is a compulsive liar. Amongst those critics are the parents of a child he confessed to having murdered in the late 1970s. In response to these accusations, Quick himself wrote an article for the Swedish newspaper Dagens Nyheter in 2001, where he said that he refused to co-operate further with the authorities concerning all open murder investigations.
