[2] On February 15, 1991, 21-year-old Eliana Macedo Xavier was strangled to death with a wire in the Riograndina sector of Nova Friburgo, followed by the eerily similar murder of 11-year-old Norma Cláudia de Araújo on September 11.
[1] According to Celso Novaes, a colonel who would later participate in the manhunt for the De Oliveira brothers, Ibraim was mistreated and sexually abused during his stay at the facility, which caused a profoundly negative effect on his personality.
For their modus operandi, they would target people living in isolated farms with various weapons, purposefully avoiding harming them from the neck down as to not leave traces, and would always take souvenirs.
[2] Their first recorded non-fatal attack took place on December 12, 1994, when they attempted to rape a woman named Carmén Augusto dos Santos in São José do Ribeirão, but she managed to escape.
[3] Their first confirmed murder took place on February 27, 1995, when they stoned to death 30-year-old João Carlos Maria da Rocha and attempted to kill his 39-year-old wife Elizete Ferreira de Lima, who survived by throwing herself into a nearby ravine and pretended to be dead.
Upon hearing this, a mob of angered residents stormed the family home, prompting the parents and the younger children to allegedly flee the city and relocate to Itaboraí.
[1] The brothers' last confirmed crime took place in the early hours of November 24, when they invaded a farm in Mariana, Sumidouro and burgled it while the owner, 35-year-old Vera Lúcia Matias, was still inside it.
[1] By December 1995, approximately 700 people consisting of BOPE agents, military police officers and civilian volunteers were participating in the manhunt for the De Oliveiras.
On December 16, a 46-year-old woodsman named César Araújo Pinto spotted a man resembling Ibraim loitering around the Barro Branco farm in the village of Sítio do Coronel, which he immediately reported to a nearby search party.
[6] Despite the lengthy sentence, Henrique de Oliveira was paroled sometime in 2015, but shortly afterwards was detained on drug possession charges and given an additional 7 years imprisonment at the Márica Prison.
