Jorge del Carmen Valenzuela Torres was born on August 23, 1938, in Cocharcas, Chile. He was the son of Melvina Torres Mella and Carlos Alberto Valenzuela Ortiz. Carlos Valenzuela died in 1943 when Jorge was only five years old. After this loss, Jorge's childhood took a difficult turn. When he was seven years old, his mother remarried. She married one of Carlos' older sons from a previous marriage. This change made Jorge leave his home. After leaving home, Jorge traveled from city to city. He took any jobs he could find to survive. Life was tough for him as a child, and he often ended up stealing animals and other goods to get by. 

On August 20, 1960, Jorge del Carmen Valenzuela Torres was at a ranch he had built with Rosa Elena Rivas Acuña, a widow with five children. He had been waiting for Rivas to return with money from her widow's pension so he could buy alcohol. However, Rivas could not get the money because of a bus malfunction. When she came back without it, Valenzuela became extremely angry.

In his fit of rage, he killed Rivas using a scythe. He then turned his anger on her five children, one of whom was just a six-month-old baby. After committing these acts, Valenzuela fell asleep in his drunken state.

When he woke up and realized what he had done, he placed stones over the bodies of the victims for reasons that are still unclear. He then fled the area, changing identities to evade capture. He used names such as "Jorge Sandoval Espinoza" and "José Jorge Castillo Torres." While on the run, he was also suspected of killing a man named Pedro Ojeda, but he was never charged with that crime.

Several days later, a local landlord, Exequiel "Quelo" Dinamarca, discovered the bodies and reported them to the police. About a month later, Valenzuela was found in the area of General Cruz in Pemuco. Two locals managed to capture him in a sack and handed him over to the police.

After he was arrested, Valenzuela showed signs of remorse for his crimes and worked to improve himself in prison. He learned to read and write, became a more committed Catholic, and even learned guitar-making. Despite his efforts to reform, Valenzuela was executed by firing squad on April 30, 1963. His execution raised questions about the justice system and the idea of rehabilitation.
