Óscar García Guzmán

Guzmán's first victim was his own father, whom he murdered at 16 years of age in 2006.[11] He confessed to the crime during a phone call to his mother from prison in January 2020.[2][18][12] Eventually, he formally admitted his guilt of the crime to the prosecution.[19] While the circumstances surrounding his father's death have not been disclosed to the public, the prosecution has confirmed that Guzmán was indeed responsible.[20]

His second and third victims were a man identified only as "Tomás" and the man's daughter, identified only as "Mónica", respectively. Guzmán first encountered Mónica on September 10, 2012, at a high school in Otzolotepec, where he quickly became infatuated with the girl and began stalking her. He went to her house and decided to rifle through her belongings, unaware that the girl's father, Tomás, was there. After being discovered by the latter, Guzmán decided to kill him, stabbing the man repeatedly and finishing him off with an axe. He then waited for Mónica to return, with Tomás' remains still in the house. When she arrived, Guzmán subdued her using krav maga and took her to his house in Villa Santin, where he kept the girl alive for two weeks, repeatedly sexually assaulting and torturing her, before ending her life by beating her to death two days before her birthday. He then dismembered her body, put the remains in cardboard boxes, and threw them in a ravine in El Mirador, Mexico City.[10][11][13][21]

Guzmán's fourth victim was Adriana González Hernández, a 27-year-old psychology student at the Insurgentes University of Toluca, who disappeared on March 24, 2017, after leaving her home in the El Ranchito neighborhood in Toluca.[22][23][24] According to relatives, a few days before Hernández's disappearance, she presented Guzmán as her "boyfriend" at a family gathering. Guzmán later confessed to activist Frida Guerrera Villalvazo that he kept Hernández alive until February 2018.[1]

His fifth victim was Martha Patricia "Patty" Nava Sotelo, a 25-year-old criminology and law student who disappeared on February 9, 2019, in Huixquilucan.[22][25] Months before she vanished, Nava expressed concerns to her family that somebody was following her, in particular, the driver of a black truck.[26] It is believed that Guzmán was familiar with the Nava family, as his victim's mother was his neighbor. After her disappearance, Nava's final cell phone reception was determined to be near Guzmán's Villa Santin house. She was held captive under the effects of Rivotril (a brand of clonazepam) for several days until her death sometime later that same month.[27]

The last victim was Jéssica Guadalupe Orihuela, a 23-year-old psychology student studying at UNITEC with Guzmán, who disappeared on October 24, 2019, after leaving her home in Colonia.[28] Guzmán had reportedly begun harassing her months before her abduction.[29] When Orihuela vanished, her family believed that Guzmán was responsible; they went to his house on several occasions to speak with him, but Guzmán repeatedly denied having seen Orihuela and ended up threatening them if they didn't "stop bothering him."[30] Family members remained outside the house beginning on October 26, claiming that they saw Orihuela through the windows. However, the police were unable to act on the family's claims without a court order, which took until October 30 to arrive.[30] The police entered the house on that date, but by then, Guzmán had fled. While examining the house, they found Jéssica's strangled body in the bathroom. She had reportedly been killed just hours prior to discovery.[29][30]

After evading capture following the police search of his home on October 30, 2019, Guzmán taunted authorities over social media for their failure to arrest him.[9] He also threatened to continue killing more women if the authorities were not able to return his pets and/or guarantee their safety.[8][9] Guzmán was captured on December 6, 2019, in the Cascos de Santo Tomás neighborhood in Mexico City,[18] after he was located by agents of the Attorney General's Office after he connected to public wifi during a music festival.[13]
