More than two months after his son’s death in a car, a US man who prosecutors say sat in his office exchanging nude photos with women while his son sat in the car for hours has been charged with murder.

A man who prosecutors said intentionally left his 22-month-old son strapped inside a hot car to die because he wanted to live a child-free life will remain jailed pending his trial, a judge ruled.

US prosecutors say a man unhappy in his marriage exchanged nude photos with several women as his son died in a hot vehicle.
