A serial killer is someone that commits a series of murders. These series of murders are uasually committed by people who have had a rough childhood or brain deformities. This is what happened with Pedro Rodrigues Filho. He is one of Brazil’s most prolific killers. Some people call him “a brilliant psychopath” and some call him simply a sociopath. Pedro Rodrigues Filho was born on a farm in Santa Rita do Sapucai. His father beat his mother while she was pregnant with him. This caused him to have a deformed skull.

He killed him because he fired his father
