(AP) Five children are in protective custody after a neighbor found one of them locked out of his Kansas City home in freezing weather.

The neighbor heard the 6-year-old boy crying around 9 p.m. Sunday, when the temperature was about 15 degrees.

 Police were called, and the boy told officers he fell asleep inside the family’s car on the way home from dinner. He woke up alone in the car and couldn’t get inside the house.

A man and woman in the house told police they thought all the children were upstairs sleeping. The adults were being questioned Monday.

Police said the home lacked heat and hot water and had other problems. Along with the 6-year-old, three other boys and a girl were in protective custody.
