A woman is in custody and accused of trying to kidnap a four-year-old girl at a San Antonio Walmart. Officers arrested 35-year-old Jessica Vega on Tuesday. Vega reportedly grabbed a woman's shopping cart in the Walmart at Loop 1604 and Potranco Road and pushed it away with the woman's daughter sitting in it. A store employee intervened and the mom grabbed the girl from the cart. A loss prevention officer reportedly recognized Vega from an earlier incident at another Walmart. Vega is charged with attempted kidnapping.
