Julio Segundo Pérez Silva (born July 15, 1963) is a Chilean taxi driver and serial killer who raped and killed at least 14 women and girls between 1998 and 2001.
Working as a taxi driver, he intercepted girls and young women with offers of free rides, then would take them somewhere remote, where he would rape and kill them with blows to the head.
After threatening her with a knife and raping her, he tied her hands and threw her into the Huantajaya Pique, which is more 220 meters deep.
Then, on April 5, he attacked Katherine Arce, whom he raped and murdered like Angelica Lay, then buried her body in an unofficial garbage dump.
It was at that moment that Pérez kidnapped, raped and killed her, leaving her body in Huantajaya along with the corpses of Sánchez and Zola.
He raped and murdered Macarena Montecinos in the "Pampa El Molle" sector, who suffered the same fate as Lay and Arce.
The luck would be different this time, since the father of the last minor mobilized the relatives of other victims, who according to the authorities and the police had fled from their homes, immersed in poverty, to Peru or Bolivia, looking for a better future.
Because of this, Pérez did not attack for nine months, but on April 17, 2001, he struck again in the sector "Autoconstrccíon" where he intercepted a child under 16 years of age, only identified as Maritza, threatening her with a knife and raping her, but did not kill her.
On October 4, 2001, Julio Pérez made this last attack, when a young woman identified as Bárbara Nuñez survived.
He intercepted and attacked in the same way he did with other victims, the difference was that Pérez confessed to being the murderer; After he had hit her with a stone on the head and thinking she was dead, he left.
During his trial, he was monitored 24 hours a day and subjected to sleep control, after he tried to commit suicide in his cell with a shoelace wound to a toothbrush.
So far, the names of five other disappeared young and adult women emerged in Alto Hospicio area between April 1999 and August 2001.
