Brazilian serial killer, believed to have murdered between 3 to 13 gay men in
São Paulo.According to Botton, he was raped by a truck driver when he was eight, causing him to develop a deep hatred towards those who were physically stronger than him. Around this time, he realized that he was attracted to other men, and when he was a teenager, he started offering sexual services to older men who were attracted to his muscular physique. Between 1986 and 1989, a mysterious series of murders against homosexuals began plaguing São Paulo, but was largely ignored by police due to social stigma and unwillingness of potential victims outing themselves as gay by reporting it to the authorities.
Confirmed victims:
- José "Zezinho" Liberato
- Antônio Carlos Di Giacomo
- Manoel "Maneco" Iraldo Paiva
When brought to the police station, Botton admitted that he had killed seven gay men from 1986 onwards, explaining in detail how he would repeatedly stab them post-mortem. According to him, most of the killings were a result of the victim underpaying him, but on a few occasions the reason was a negative remark: in the Di Giacomo case, he claimed to have killed the psychiatrist because he complained that he smoked too much.
