A man who pulled over to help a woman who had just been involved in a crash was struck by a hit-and-run driver early Thursday morning.
San Antonio police said the Good Samaritan -- 39-year-old Luis Saul Vasquez -- saw a woman spin out and crash into a guardrail along the Highway 281 southbound access road inside Loop 1604.
He had stopped to help the driver when was struck by a white BMW around 3:30 a.m.
Police said the driver who struck the Vasquez did not stop, but a license plate was left behind at the scene and officers hoped it would lead them to the driver.
"If you're involved in an accident, the best thing to do is stop and give information or stop to check on the people, and see if they need help, because otherwise you could face a felony charge for failure to stop and render aid," said Roger Zuniga, patrol officer for the San Antonio Police Department.
Vasquez was rushed to University Hospital with a broken leg and facial fractures, but was expected to survive, police said.
Zuniga said it was important for other Good Samaritans to know that sometimes the best way to help is to call police, but not to get out of the car.
"People have good hearts," Zuniga said. "I understand people want to stop and help and that's great, but it can be a very dangerous situation, and they're putting their lives at risk when they do this."
