A 21-year-old man has been sentenced to 40 years in prison for the murder of a teenager who was attempting to protect his sister during a violent encounter outside their home in Kyle, Texas, in 2020.
Isaac Arispe, who was just 15 years old at the time of the crime, was tried as an adult and found guilty in March of killing 19-year-old Christopher Trevino. Following his conviction, he chose to have his sentencing decided by the judge.
During the sentencing phase, court officials presented evidence detailing Arispe’s troubling behavior while in custody. Over the course of three years, he was linked to more than 30 documented incidents involving assaults on fellow inmates and possession of contraband. Additionally, testimony revealed his affiliation with a criminal street gang.
Family members of Trevino spoke during the proceedings, sharing the deep emotional toll his death has taken on them. In her decision, Judge Tibbe recognized Arispe’s age at the time of the murder but emphasized the need for a sentence that reflects the significant harm caused to Trevino, his loved ones, and the broader community.
The Tragic Incident
Christopher Trevino was fatally shot just days before Christmas 2020 while he was trying to intervene as his sister was being threatened at gunpoint. At the time, she had arranged to sell marijuana to a classmate via Snapchat. When the buyer arrived, he brandished a gun instead of cash.
As Trevino returned home, he noticed the escalating situation and rushed across the street to protect his sister. Tragically, he was shot once in the chest by Arispe, who fled the scene but was apprehended shortly thereafter at a nearby apartment complex.
Evidence presented during the trial indicated that Arispe had been in communication with Trevino’s sister, allegedly soliciting bullets and expressing intentions to commit a robbery.
Remembering Christopher Trevino
In a show of support for Trevino’s family, friends and community members held a fundraiser to honor his memory. The event featured food sales and car washes, with proceeds going to the family.
Trevino was a dedicated student at Texas A&M University-San Antonio, pursuing a business degree while adapting to online learning due to the COVID-19 pandemic. He had recently started working at Home Depot and was known for his intelligence, kindness, and desire to help others. His family recalled him as a bright young man with a smile that could light up a room, often referred to affectionately by his mother as “Binky baby.”
His mother expressed her grief, sharing that her son was destined for greatness and had a loving spirit that touched many lives.
