Police are at the Texaco on Fannin near I-45, where two other victims were located by officers earlier this morning.
All three victims were transported to Memorial Hermann Hospital, but are expected to survive their injuries.
We're hoping to learn more from Houston police shortly, but so far, investigators said two people inside a vehicle pulled up and opened fire on the victims.
About 12 shots rang out before the suspects sped off in an unknown vehicle.
When officers arrived, they found the shooting victims hanging off the sidewalk in the 1100 block of Webster.
The Texaco is near a bus station, but there is no word on whether there were any witnesses.
We do not know the motive in the shooting.
