An 8-year old boy and a 10-year old girl sneaked into the trunk of a car on Wednesday and when they were found, the boy had died.
The girl, who could hardly breathe at the time, was rushed to a hospital.
She succumbed to brain damage the next morning, local media reported.
Doctors said a lack of oxygen in the trunk had damaged their brains. Hot weather also worsened their conditions, doctors added.
The two families of the two children were preparing for a party.
The parents were so busy that they only noticed the kids’ disappearance after a while, when it was too late.
