SAN ANTONIO – In a significant development in local crime news, a man named Nathan Martinez has been found guilty of murder for the tragic drive-by shooting that resulted in the death of 17-year-old Julian Junior Robledo. This event unfolded in August 2023, while Robledo was sitting under a carport with his mother in the 2800 block of Mosscircle Drive. Sadly, he succumbed to his injuries just two days later.
The case against Martinez was robust, with ballistic evidence linking him to not just this incident, but also to multiple crime scenes. Investigators uncovered social media posts where Martinez allegedly boasted about “taking down a rival gang member.” These posts also mentioned a firearm modification called a switch, which can make a gun fully automatic, raising serious concerns about gun violence in the community.
It’s worth noting that this isn’t the only serious charge Martinez is facing. He is also linked to a separate capital murder case from June 2022, where two men were killed and five others injured during a barbecue gathering in the 2500 block of Patron Drive. That case is still pending, adding another layer to Martinez’s criminal history.
As the legal proceedings continue, Judge Stephanie Boyd is set to announce Martinez’s sentence on Tuesday at 1:30 p.m., according to court records. This case highlights ongoing issues related to gun violence and gang activity in San Antonio, reminding us of the need for community awareness and engagement in preventing such tragedies.
