Trigueiro raped and murdered five women between April 17, 2009, and February 26, 2010, when he was detained by Minas Gerais Civil Police in the Lindeia neighbourhood, near the industrial district in Contagem.
Police officers discovered that he tracked down the victims' cell phones, with Trigueiro himself confessing to the murders after his arrest.
On February 2, 2010, police had disclosed that there was a common behavioural pattern in all the murders, and that an expert found semen in the three 2009 victims which was from the same perpetrator.
