Marcos Antunes Trigueiro

Marcos Antunes Trigueiro, known as the Industrial Maniac and the Contagem Maniac (born in Brasília de Minas, Minas Gerais on May 29, 1978) is a former Brazilian driver accused of being a serial killer of women who operated in the Contagem and Belo Horizonte cities. 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. Delegate Edson Moreira, one of those responsible for the case, announced on February 26 that at least three women were able to escape the maniac.
