Julian Castro, running for the Democratic nomination for president, also a San Antonio native, expressed his shock.
"As we await more information, my heart goes out to the victims, their families, our city, and our country," Mr Castro tweeted. "Enough is enough - we must act on gun reform now."
Local journalist Jacob Beltran tweeted that witnesses heard arguing just moments before shots rang out.
Locals have been urged to stay away from the shopping centre and police have established a crime scene.
