A jilted teenager who massacred four members of his ex-boyfriend's family, set their home ablaze, and killed three dogs is set to spend the rest of his life behind bars. Miguel Diego Sandoval, now 21, pleaded guilty to four counts of first-degree murder over the brutal attack in California, US.
Prosecutors said Sandoval was furious after his relationship ended and carried out the killings as an act of revenge. His ex-boyfriend, who was the brother of two of the victims, was said to be Sandoval's intended target but was not at the property when he struck.
Attack Details
Sandoval waited outside the family home until the occupants had gone to bed before entering. He then shot his ex's siblings Janvi Maquindang, 21, and Christine Aca-ac, 25, as well as their partners Edwin Garcia, 24, and Matthew Montebello, 21.
Sandoval, who was 19 at the time of the attack, then set the house on fire before fleeing, killing three family dogs trapped inside. A 16-year-old girl who was also inside the property managed to survive after locking herself in a bedroom and calling 911.
Victims Remembered
The four victims have since been remembered by their devastated loved ones. Janvi was described as a bright and successful young man, while Christine was remembered as a loving sister who helped care for younger members of her family.
Edwin, who was engaged to Christine, had aspirations of becoming an educator. Matthew was described by his family as curious and driven.
Guilty Plea and Sentencing
Sandoval later admitted to the killings, which took place in November 2024, and pleaded guilty to four counts of first-degree murder on August 13 this year. He also pleaded guilty to attempted murder, residential burglary, arson, animal cruelty and child abuse charges.
Los Angeles County District Attorney Nathan Hochman described the massacre as a calculated act of violence. He said: “The defendant was jilted when he broke up with his boyfriend and then did something unimaginable when he killed four innocent people.”
Sandoval is due to be sentenced to life in prison without the possibility of parole on November 17.
