A 37-year-old Michigan woman has been arrested after three girls — ages 6, 3 and 2 — were left in a locked minivan on what would become the hottest day so far this year.
The woman was shopping in Clinton Township when police were called at about 9 am local time. The van's front windows were opened slightly.
The National Weather Service says the temperature was about 25C at the time. It reached 35.5C in the Detroit area.
Clinton Township police Captain Richard Maierle tells the Detroit News the 6-year-old girl was "sweating profusely" when officers coaxed her into unlocking a door.
