San Antonio police are hunting for a man who ran from the scene of a crash that critically injured a woman on the city’s South Side, at Pleasanton Road and Formosa Boulevard.

“She’s not doing too well. Doctors are doing the best they can for her,” said Sgt. Javier Salazar, spokesman for the San Antonio Police Department, referring to the injured woman.

The driver who is believed to have caused the crash may have been injured too, police said.

Salazar said the man, who is in his 20s, was driving a pickup east on Formosa Boulevard just before 9 a.m. Friday when an officer in a Bexar County Hospital District patrol car spotted him.

He said the officer noticed that the truck was speeding, and dragging a trash can beneath it.

"He went to try to get behind the vehicle. That vehicle accelerated at this point, at this intersection, and struck a vehicle driven by a single female," Salazar said.

The impact sheared off most of the driver’s side of the woman’s SUV.

The woman, who’s believed to be in her 50s or 60s, was rushed to a hospital by ambulance.

The driver of the pickup was last seen running toward a nearby apartment complex.

Police used a helicopter to try to locate him from above, but, as of noon Friday, had not found him.

They said the truck he left behind was stolen and had no seats inside, only a folding metal chair.

"It does show some signs that it was used for some sort of a trafficking offense, whether it be undocumented immigrants or drugs," Salazar said.

When he is caught, the driver could face a list of charges, including attempted murder, Salazar said.

However, that could change depending on the fate of the injured woman, he said.
