Twenty-one-year-old Melissa Garcia was charged with three counts of child endangerment and operating a vehicle with no consent. She was in custody Sunday at the Johnson County Jail on a $10,000 cash only bond. Garcia was arrested Saturday night in Iowa City. Police said investigating officers found that Garcia had allegedly let the 12-year-old drive the car with three other children in the vehicle, which had been weaving all over the road. It was immediately unclear if Garcia had an attorney. A phone listing for Garcia could not be located on Sunday.
