Matthew Escalante Argumedo was 20 when he was shot in East Austin after arriving to meet a man his girlfriend knew as Rudi. On the afternoon of November 7, 2024, he got out of his car in the 2600 block of Rosewood Avenue while on the phone; his girlfriend heard several gunshots moments later, found him with a gunshot wound, and he died at a local hospital on November 8, 2024.

Witnesses saw three men run from the scene, and surveillance footage shows one man drawing a handgun. Investigators analyzed ballistics, social media records, and cellphone location data during a yearlong probe. A U.S. Marshals task force arrested 21-year-old Rudy Tito Zamora on November 20, 2024, and charged him with murder. Later developments in 2026 included charges against two additional men named in the investigation.

Did anyone in the Rosewood Avenue area that afternoon see the three men or the vehicle Matthew arrived in?
