Andrés Ulises Castillo Villareal

Andrés Ulises Castillo Villarreal (born 1980) is a Mexican serial killer, who was active in his hometown of Chihuahua City. He raped and murdered at least three men, as well as raping a teenager between 2009 and 2015. He confessed to around 12 murders, earning him the nicknames The Chihuahua Ripper and The Urban Development Ripper. He can be classified as an organized, sedentary and hedonistic murderer motivated by sexual compulsion. He was sentenced to 120 years imprisonment in 2017.

Modus operandi Castillo, who was a narcomenudista (a small-time drug dealer ), attracted his victims (young men who used methamphetamines) with the promise of giving them drugs. He then drove them to secluded places on the outskirts of town or his own home, where he would drug and intoxicate them. Afterwards, he would hit them on the head with a blunt object to first incapacitate and rape them, before hitting them on the head to kill them. The bodies would then always be dismembered with a coping saw. Castillo would transport the remains in a wheelbarrow and abandon them in vacant places, where he would either hide them partially or bury them completely. Additionally, he would always leave toys next to the mutilated bodies as a "signature".

Confirmed victims

Murder of Lorenzo Ernesto Olivas Barrios Castillo's first identified victim was Lorenzo Ernesto Olivas Barrios, a 22-year-old man from Delicias, who had moved months before his death to the city of Chihuahua to work in a food company. He lived with relatives in Colonia Vista Hermosa before disappearing on November 13, 2015, saying to a relative that he was going to buy "some dinner", but never returned. Three days later, on November 16, his relatives reported his disappearance; they would not hear any news about him until the following day, when the dismembered remains of a man were found by some neighbors of the Urban Development Company. After dismembering the body in the bathroom, Castillo coerced a teenager, under threats of killing him, to help transport the remains. They then returned to Castillo's home on Ninth Street, where they cleaned and painted the blood-stained walls. Castillo later raped the teenager.

All the similarities between the two findings of Lorenzo Olivas' remains and this new discovery, made it clear that they had been killed by the same person. The victim was identified as Daniel Alfonso Rodríguez Morales, nicknamed "El Troya", a 22-year-old who lived in the same Urban Development neighborhood. He had been seen alive for the last time on the same day his remains were discovered. Two years earlier, Daniel had been arrested for trying to break into a car.

According to the reconstruction of the events following the murder of Lorenzo Olivas, the murderer deceitfully moved to a friend's house located on Álamos Street in the Urban Development neighborhood. He continued to harass the teenager he had previously forced to help him, making him move into his house on December 13. Castillo then invited his new victim to the friend's house, drugged him in front of the host and the teenager, and then proceeded to kill him by hitting him on the head with a rock. He threatened both witnesses with death, forcing them to help dispose of the body. In reality, Castillo had drugged, raped and beaten Fernando in the same house where he had killed Daniel Rodríguez.

Possible victims Upon his arrest, Andrés Castillo confessed to killing 12 people, but according to the prosecution of Chihuahua, he might be involved in about 20 murders. Some of the victims attributed to the killer are: Miguel Ángel Castillo Quintana: 21-year-old man, murdered on August 7, 2015; his killer had hit him on the head to kill him, and he was found on the day of his death in the Ferro-construction warehouse building on Nueva Spain Avenue. He was face down, naked from the waist down. Gabriel García Hernández: his dismembered body was found on August 3, 2015, beaten to death. He emphasizes the fact that, in his last crime, he was very careless compared to his previous murders, where he had conducted himself in a methodical way, leaving no evidence and believing that he would never be captured. On December 5, 2017, he was sentenced to 120 years imprisonment.
