Police said the case began as an online jewelry sale arranged through OfferUp.
SAN ANTONIO, TX — An 18-year-old man has been arrested after San Antonio police said a planned robbery tied to an online jewelry sale left a father and son shot multiple times earlier this month.
Jacob Farias Jr. is accused of taking part in the robbery, which investigators said was set up through OfferUp and disguised as a meeting to buy jewelry. The arrest moves the case from an active search for suspects into the early court process, while police continue working to identify another person they say was involved.
According to an arrest affidavit cited by police, the father and son agreed to meet with people who appeared to be interested in buying jewelry. Investigators said the meeting changed once Farias and another unidentified suspect pulled out guns. The two victims were shot during the encounter, police said. Their names, ages and full medical conditions were not released in the early reports reviewed after the arrest. Police have not said whether the jewelry was recovered or whether other property was taken.
The San Antonio Police Department said Farias was arrested in connection with the shooting after investigators linked him to the robbery. Police have not publicly identified the second suspect. The affidavit says the robbery was not a random attack but a meeting arranged around an online sale. Detectives described the setup as a planned robbery, with the jewelry sale used as the reason to bring the victims to the meeting. No full timeline of the shooting was released, and police had not provided a complete account of how officers first identified Farias.
The case adds to a series of San Antonio investigations in which police have said online sales or private transactions became violent. In this case, investigators focused on the OfferUp meeting and the statements included in the affidavit. Police said the father and son were shot more than once, a detail that raised the seriousness of the case even though the victims survived. The available records do not say whether either victim fired a weapon, whether surveillance video was collected or whether police recovered shell casings, phones or messages from the sale.
Farias now faces the court process in Bexar County. Police did not announce that all suspects had been arrested, and the unidentified person described in the affidavit remained a key part of the investigation. Detectives are expected to keep reviewing phone records, messages tied to the online sale, witness statements and any video from the area. Formal charging details, bond information and future hearing dates were not immediately available in the public reports reviewed after the arrest.
The shooting drew attention because the victims were family members and because the robbery was tied to a common online marketplace transaction. Police said the suspects presented themselves as buyers before the meeting turned violent. The father and son were left with multiple gunshot wounds, and investigators later moved to arrest Farias as one of the people accused of taking part. Officials have not released a detailed statement from the victims or their family, and the motive beyond robbery remains under investigation.
The case remained open as of Sunday, with Farias in custody and police still seeking more information about the second suspect and the full sequence of the shooting.
