San Marcos, TX — Arrest Made in Double Homicide Near San Antonio and Guadalupe Streets
The community of San Marcos, Texas, is grappling with the devastating aftermath of a violent shooting that left two young men dead and another injured in the early hours of Saturday, July 19, 2025. In connection with the tragic incident, San Marcos Police have arrested 18-year-old Jermiah Jayden Tobias, who now faces serious charges, including two counts of capital murder and one count of aggravated assault with a deadly weapon.
The Shooting Incident — How It Unfolded
According to the San Marcos Police Department (SMPD), the violent altercation began as a fight between two men near San Antonio and Guadalupe Streets, a bustling area in downtown San Marcos known for its nightlife. What reportedly started as a dispute quickly escalated into chaos when, during the scuffle, a third individual allegedly stole a necklace — an action that police believe ignited a deadly chain of events.
Witnesses say that in the moments following the theft, Jermiah Tobias allegedly opened fire, discharging multiple rounds in the crowded area. The sudden eruption of gunfire caused panic among bystanders and resulted in catastrophic consequences.
The Victims — Lives Cut Tragically Short
The gunfire struck 24-year-old Anthony Barrera, who was pronounced dead at the scene despite the efforts of first responders. Barrera, known among his family and friends for his vibrant personality and kind heart, leaves behind grieving loved ones who are now mourning his senseless loss.
20-year-old Alek Pacheco, another victim of the shooting, was rushed to a nearby hospital in critical condition. Despite the best efforts of medical personnel, Pacheco succumbed to his injuries shortly after arriving. His death marks a second tragic loss stemming from the same incident — a heartbreak felt deeply by his family, friends, and the community at large.
A third victim, who has not been publicly identified, sustained a graze wound from the gunfire. Thankfully, this individual was treated and later released from the hospital.
Arrest and Charges — Justice in Motion
After an intensive investigation, San Marcos Police arrested Jermiah Jayden Tobias in connection to the double homicide. Tobias now faces two counts of capital murder, a charge that carries the possibility of life imprisonment or even the death penalty under Texas law, as well as one count of aggravated assault with a deadly weapon.
Tobias remains in custody as the investigation continues, with detectives working tirelessly to gather evidence, interview witnesses, and determine whether additional individuals may be involved in the incident.
