Horrible news from Carrollton, Ga.: Police say twin 15-month-old girls died after being left in the back of an SUV, USA Today reports.

The girls were rushed to a local hospital, where they were pronounced dead. The girl’s father, 24-year-old Asa North, has been charged with two counts each of involuntary manslaughter and reckless conduct, CNN reports.
