Michael Chavez was an 18-year-old Hispanic male who was killed on January 4, 2014, at a home in the 5600 block of Porsche Lane in Southwest Austin. Police received a call about the incident at approximately 5:28 p.m.; Chavez was pronounced dead at University Medical Center Brackenridge shortly after emergency crews arrived.

Investigators reported the suspects fleeing in two vehicles, a dark four-door sedan and a green Cadillac from the mid- to late-1990s. Authorities examined phone records, interviewed neighbors, and canvassed for surveillance footage, but faced difficulties because there were no direct witnesses and the suspects used multiple vehicles to escape. No arrests or formal charges had been announced and the case remained open.

Does anyone have information about activity in the Porsche Lane area on January 4, 2014, or about a green mid- to late-1990s Cadillac seen that evening?
