Man guilty of slaying teen faces sentence

Nathan Martinez stands to receive his sentence this Thursday in Bexar County court after a jury convicted him of murder. The verdict was reached on November 6, 2026, ending the legal proceedings for a death that occurred more than three years ago.

The homicide involved Julian Robledo, who was 17 years old at the time of his death. According to court records, the killing took place on August 15, 2023. Martinez had pleaded not guilty to the charge before the jury returned its guilty verdict.

San Antonio police described the scene as Robledo and his mother sat outside a home having coffee. A vehicle passed by and fired shots at them, striking the teenager. The department identified Martinez as the person who killed the victim in that incident.

Detectives linked Martinez to the crime through evidence from a separate shooting that occurred days after the August 2023 homicide. In that later incident in southwest San Antonio, Martinez was shot while firing back at his attackers. Physical evidence recovered from that second scene matched items found at the Robledo crime scene, connecting the two cases for investigators.

At the time of his arrest in 2023, authorities said they were investigating Martinez in connection with at least three shootings that occurred between 2022 and 2023. One of those incidents took place during a family gathering in June 2022. Officials reported that two people died and five others were injured in that shooting.
