AUSTIN (KXAN) — The Austin Police Department is investigating a man’s death in downtown Austin as a homicide on Tuesday. No suspect is in custody.

APD said officers responded to the area of Sixth and Sabine Streets just before 11 a.m. after reports from multiple callers saying a man was shot.

Officers found the man at the scene with “obvious trauma to the chest.” APD said medical assistance was given to him, but he was pronounced dead at 11:16 a.m. Police said he was in his 30s. Austin-Travis County EMS confirmed one person died at the scene.

Now, homicide detectives are looking into security footage and canvassing the area to figure out what happened. APD said it’s believed an argument broke out between two or more people which led to the shooting.

No suspect has been identified yet, but police said it’s an isolated incident with no threat to the public. This is Austin’s 49th homicide of the year.

APD said if anyone was in the area and saw what happened, call the APD Homicide Tip Line at (512) 477-3588.
