A Nebraska mother is facing charges of child abuse after allegedly leaving her three-month-old baby in a hot car to go horse riding at a fairground. Cara Dugan, 40, was arrested while riding a horse at the Merrick County Fairgrounds on Saturday afternoon, a day that reached 90F, after passers-by heard her baby crying in a hot pickup truck and stepped in to help, according to the Merrick County Sheriff’s Office. Despite being in the truck with windows only “partially ajar” and no air conditioning for a “substantial amount of time”, the child did not receive any injuries, and is now in the care and custody of the Nebraska Department of Health and Human Services, according to the sheriff’s office.
