A Michigan woman accidentally locked her keys and her infant daughter inside her minivan. “I grabbed a piece of asphalt and started banging, but it would not break,” Lacy Guyton said. She was with her grandmother, Mary Riley, who called 911. To their utter astonishment, the 911 operator in Waterford said she could not help. “My granddaughter just put her baby in the car and the car door locked and we can't get in it,” Riley told the dispatcher. “We don't unlock vehicles,” the operator responded.
