AUSTIN (KXAN) — The Austin Police Department is investigating a homicide after a man died at the hospital Wednesday after being shot at a north Austin gas station earlier this month.

APD said Antonio Castro, 72, died at the hospital Aug. 24 at 9:47 a.m.

Castro and another person were shot the morning of Aug. 9 at a gas station located at 1600 Ohlen Rd., according to Austin Police. That’s near Payton Gin Road and U.S. Highway 183.

Both Castro and the second victim were taken to the hospital with gunshot wounds.

APD said the suspect went up to the second victim behind the gas station, pulled out a gun and shot both them and Castro, who were sitting next to each other.

An autopsy was done Thursday, which determined Castro’s manner of death a homicide.

Surveillance video of the suspect was released Aug. 29. In the video, the suspect is seen approaching an individual behind the gas station.
