Their worst nightmare happened to a couple in Detroit, Michigan.
Their five-year-old boy wandered off in the middle of the night on a freezing cold night, wearing only a tee shirt and his underwear.
The boy’s mother said that she tucked him in at 10 pm, and the next morning he was not in his bed.
The child somehow left his suburban Detroit home and the family called police on the morning of January 23.
Police searched for the child and found him dead in a nearby snow-covered playground.
The police did not say how the boy was able to get out of his house or when he wandered off. The incident is not considered suspicious.
The temperatures on the night the child died were as low as 27 degrees.
