Boys died because of heat

Boys died because of heat, police say : "The boys had been seen playing in the broken-down vehicle at the Yarunga Street home about three hours before the boot was opened."
They were so little. It seems so very sad. No one heard any cries for help. I expect it will all make sense in time. I was wondering if they accidentally clicked the lock on the boot which allows or disallows opening from inside the car. I did it by accidnet the other week and couldn't work out why my boot wouldn't open. They were probably too little to work out how to get out through the back seat and it may not have been possible anyway. Little children in cars on a hot day would be very vulnerable. It is hard to breath when you get into a hot car. It is just so sad. Little kids and cars like little kids and pools just do not mix over here and we need to keep reminding ourselves of that. I cannot imagine how the parents must be feeling.
