A police spokeswoman says she told investigators that she and her 4-year-old child walked a mile to a gas station.In 2009, Redmond police cited Biryukova and her husband, Solomon Metalwala, for leaving a child unattended in a vehicle. The case was dismissed after they agreed to probation, community service and a 10-week parenting class.
