A group of people, including children, are going from store to store in southern Kentucky stealing large amounts of baby formula and diapers, according to the Laurel County Sheriff's Department.
They say there's a large black market for baby formula, so it's popular among thieves.
The crimes happened at Dollar General stores and Walmart stores, and investigators say they have been increasing since last week.
Authorities are looking for a woman, two teen boys and two young children.
They may be in a maroon Mercury Mountaineer with a Kentucky tag of "613 BEM".
Anyone with information is asked to call the Laurel County Sheriff's Department at 606-864-6600.
