Based on preliminary information, Gonzalez says it's believed that four juveniles were riding on the ATV, which included two 9-year-olds, a 14-year-old, and a two-year-old. Three of them were taken by Life Flight, according to the sheriff. Gonzalez says that the mom of the 2-year-old arrived on the scene and refused transport.
