Two men were shot at a downtown intersection early Monday morning possibly following a work related dispute, San Antonio police said.
Investigators said shots were fired around 2 a.m. on McCullough Avenue and North Alamo Street.
The two victims -- men in their 20s -- were parked in their car when a second car pulled up, police said.
"A passenger in that second vehicle fired several shots into the victim's vehicle, striking both victims in the abdomen," San Antonio police Sgt. Javier Salazar said.
They drove themselves to Metropolitan Methodist Hospital and were transported to San Antonio Military Medical Center, police said.
Police also investigated the scene at the hospital.
"We investigate all aspects anywhere that evidence from the shooting itself may be gleaned, and so we're looking at both scenes separately," Salazar said.
An employee at a nearby bus station said security cameras there showed the two cars pulling up in the intersection.
Police reviewed the video, but did not say whether they were able to identify the car the shooter was in.
Several people were at the bus stop when shots were fired. They were rushed inside by an employee and no other injuries were reported.
