His first murder occurred when he was only 14 and he had killed 10 people before his 18th birthday.
His first victim was the vice-Mayor of Alfenas, Minas Gerais, because he fired his father, a school guard, at the time accused of stealing the school kitchen's food.
Then he murdered another guard, supposedly the real thief.
His next victims included a drug dealer and gangsters, the latter was a group who killed the woman he lived with.
Filho was born with a cracked skull because of his father beating his mother while he was still in the womb. Later in life, his father murdered his mother with a machete. To get revenge, Filho killed his father, cut out a piece of his heart, chewed it, and threw it away.
Pedro was first arrested on May 24, 1973. He was sentenced to prison and killed at least 47 inmates while incarcerated. He later claimed a total of 100 victims. His total confirmed victims are 71.
In 2003, he was sentenced to 126 years in prison, and that was changed to 400 years after the lives he claimed in prison.
The crazy thing is that, although he had a 400 year sentence, he is already out of prison. Brazilian law states that one can only be incarcerated for 30 years. Filho served 34 years behind bars before being released in 2007.
Besides the number of killings, Pedrinho became notorious in Brazil for promising the murder of other criminals, such as Francisco de Assis Pereira, a.k.a. The Park Maniac, another serial killer.
