“We heard her accelerating, no brakes, she went up on the curb. I think she hit carts and then we heard the crash over here, said Stephanie Pruscha. “I took off running and once they said there was a baby in the car, I jumped up onto the car and once Officer Dombrowski gave the okay, I took the baby out and handed him over to her.”

Both the woman and toddler were transported by helicopter to Children’s Hospital Oakland and John Muir Walnut Creek, respectively, for treatment of major injuries. No word as to their condition.
