Ronis de Oliveira Bastos

Ronis de Oliveira Bastos (1988 – April 24, 2017), known as the Itaquaquecetuba Serial Killer , was a Brazilian serial killer who attacked ten men in the city of Itaquaquecetuba from October to December 2011, eight of which resulted in fatalities.

Before he could be brought to trial, De Oliveira was diagnosed as mentally ill and acquitted by reason of insanity, after which he was interned at the Taubaté House of Custody and Psychiatric Treatment. He remained there until his death in 2017.

Early life Little is known about Ronis de Oliveira Bastos' early life. Born in 1988 in Itaquaquecetuba, he started working as a licensed market vendor and specialized in repairing cellphones as an adult. Prior to the murders, he was described as an average young man who had no criminal record and showed no violent tendencies.

Murders Between October and December 2011, ten men were attacked in the Jardim Luciana neighborhood of Greater São Paulo, eight of whom died. Witnesses described the perpetrator as a young white man of short stature who rode around the streets on a blue bicycle and was wearing a ninja hood.

Investigation and capture With the help of witnesses, a physical profile and facial composite of the criminal was created, and police officers were dispatched to the Jardim Luciana neighborhood. Despite these measures, there were three more shootings that occurred the following weekend. Two of these victims, and the sole survivor, Jefferson Soares da Silva, managed to survive. After recovering, he identified the shooter as 22-year-old Ronis de Oliveira Bastos. This claim was not believed and he was immediately arrested for possession of illegal weaponry, with a subsequent search of his home leading to the location of shell casings identical to those found at the crime scenes, as well as the ninja hood and a backpack in which De Oliveira hid his guns. As a result, he was acquitted by reason of insanity and committed to the Taubaté House of Custody and Psychiatric Treatment. He remained there until his death on April 24, 2017, but the exact cause of death is unknown.
