Pedro Pablo Nakada Ludeña was born on February 28, 1973, in Lima, Peru. His birth name was Pedro Pablo Mesías Ludeña. He grew up in a difficult family environment. His father was an alcoholic, which affected the family significantly. Nakada's mother suffered from a mental disorder that was not clearly defined. As a child, Nakada was described as submissive and was often abused by his siblings.

When Nakada was young, his father passed away. This loss impacted him deeply. He used to defend his father from mockery by his sisters and their friends. They would sometimes make Nakada dress like a girl, which troubled him. He also reported a traumatic incident involving his brothers. They believed he had accidentally killed their pregnant dog, which led to him being raped by them. He later claimed that this incident contributed to his feelings of hatred towards homosexuals.

As a child, Nakada claimed to have tortured animals. This behavior would become a significant part of his later life. In 2003, he sought to change his life by paying a Japanese citizen to adopt him as an adult. He hoped this would help him move to Japan, believing he could pass as a Japanese descendant. He changed his surname from Mesías to Nakada as part of this process. This method was known among some Peruvian criminals as a way to escape justice.

Although Nakada never emigrated to Japan, his younger brother, Vayron Jonathan Nakada Ludeña, did move there. In 2015, Vayron was arrested in Japan after a violent incident in which he fatally stabbed six people over three days. Reports also suggest that both brothers were diagnosed with paranoid schizophrenia by family members.

Pedro Pablo Nakada Ludeña was a Peruvian serial killer who committed his crimes between January 1, 2005, and December 27, 2006. He killed his victims using 9mm pistols that were fitted with homemade rubber silencers, which he modified from slippers. Nakada claimed that he was acting on a divine command to cleanse the Earth by eliminating individuals he deemed unworthy, including drug addicts, prostitutes, homosexuals, and criminals.

His first victim was Carlos Edilberto Merino Aguilar, a 26-year-old man, whom Nakada shot on January 1, 2005. He shot Merino in the thorax and abdomen and then stole money from him, believing Merino was going to rob him.

On May 31, 2006, Nakada shot Teresa Cotrina Abad, a 50-year-old woman, twice in the head because he saw her smoking cigarettes. Later, on July 20, 2006, he shot Walter Sandoval Osorio, 44 years old, in the head. Although Sandoval was taken to the hospital, he died from his injuries shortly after.

Next, Nakada murdered Gerardo Leonardo Cruz Libya, a 30-year-old man, on August 8, 2006. Cruz was shot in the head and later found submerged in a water well. Nakada killed him to prevent Cruz from informing the police about a previous robbery and murder they had committed together.

On August 18 and 19, 2006, he shot 21-year-old Carlos Walter Tarazona Toledo and 15-year-old María Verónica Tolentino Pajuelo, respectively. Tarazona was shot after Nakada saw him smoking drugs. Tolentino was shot in the head when she approached him; Nakada later expressed regret for killing her, stating she did not deserve to die.

On November 18, 2006, Nakada killed Hugo Vílchez Palomino, robbing him after the shooting. Four days later, on November 22, 2006, he murdered three men—Luis Enrique Morán Cervantes, Pedro Omar Carrera Carrera, and Enoch Eliseo Félix Zorrilla—whom he believed were using their taxi for assaults.

On November 19, 2006, he shot and killed Widmar Jesús Muñoz Villanueva, whom he targeted due to rumors about him being a homosexual and engaging in prostitution. This crime was followed by the killings of Nell Cajaleón Pajuelo, Nazario Julián Tamariz Pérez, Didier Jesús Zapata Dulanto, Agustín Andrés Maguiña Oropeza, and Luis Melgarejo Sáenz during December 2006.

Nakada shot Nicolás Tolentino Purizaca Gamboa on December 27, 2006. After this murder, the police arrested Nakada on December 28, 2006, following a shootout in his workplace that resulted in one officer being injured.

Although he confessed to killing 25 people, Nakada was convicted of 17 murders and sentenced to a maximum prison term of 35 years.
