A four-year-old boy died after climbing into a boiling-hot car while his mum tended to her newborn baby.
Little Cyller Nelson is believed to have wandered off while his mum was busy looking after his new baby sister.
His family reported him missing at the Pine Oaks Mobile Home Park in Mobile, Alabama, and shortly afterwards a neighbour heard mum Heather Queysen screaming when her son's body was discovered.
Temperatures in the area had soared into the high 30Cs. No criminal charges are expected to be filed as the death is thought to be accidental after the little boy wandered away from his home.
Neighbour Tonya Smith told Fox 10: "It's very tragic. There's another angel in heaven now, one that didn't need to be there, he just started his life."
The tragedy is the latest in a spate of deaths involving young children in overheated vehicles.
According to website KidsandCars.org, 32 children were killed in the US last year when they were left in hot cars. The number of tragedies this year stands at 21 in the US and two in Canada.
