Leaving any child in a car is dangerous, and can be fatal.
Toddler died after father allegedly forgot about daycare stop for eight hours.
A father in the US has been charged with murder over the death of his two-year-old after the child was allegedly left in a car for eight hours.
Police in the Georgia's Cobb County on the edge of the state capital Atlanta said Justin Ross Harris, 34, had intended to drop his toddler at a daycare centre on Wednesday but had forgotten and continued onto his workplace.
They said it wasn't until after Harris had finished work for the day and started on the trip home that he discovered the child was still strapped into his restraint in the back seat -- and was by then unresponsive.
Fox News reports a witness saw Harris pull into a shopping centre carpark, stop his car across two lanes of traffic, leap out and start administering resuscitation to the child, who failed to revive. “He was constantly saying, "What have I done, what have I done" the witness is cited as having said.
Temperatures in Atlanta topped 32C on Wednesday afternoon, with estimates that the temperature inside a closed car could go as high as 54-60C in a few hours.
The report says Harris has been charged with two felony counts -- murder and cruelty to children -- and is being held without bail the Cobb County Adult Detention Center.
Parents are urged to always make sure their children are not left or inadvertently locked in a car.
