A device as cheap as $9 could have saved the life of a Greene County, Virginia toddler earlier this week. On Monday, a 25 year old mother of three was washing her 2002 Ford Explorer in the family’s driveway, while her two older children, ages 3 and 5 sat inside the parked vehicle. Her 18 month old daughter, Aeayla Camacho toddled outside following her mother as she performed this chore. Suddenly, the vehicle began to roll backwards and the mother scrambled to get her toddler out of the way. Despite injuring herself, her efforts to save her daughter were in vain. The vehicle crushed the toddler. Little Aeayla died in her driveway.
