Police say they found the mother of the toddler inside one store. She said she thought there was another adult in the vehicle when she got out. Officers questioned that, asking why she would shut the car off and lock it if that was the case.
Police say they still aren't exactly sure what happened.
Officers ended up giving the mother a $250 ticket under the Forget-Me-Not law. They say they did not arrest her for child neglect because the kid was OK and this was her first offense.
Police say the child remains with his mother, but there will be a Department of Human Services investigation.
