In CS's recent case, her parents drove to all the places that they used to go in that area, as children, when they were searching for CS in the morning after she disappeared.
I am not sure that made sense, as CS is a 4 year old who likely has no concept of where they used to go as children, or would go there in the middle of the night.
People become frantic when looking for their lost child. How far can they go? Are they hiding in a cupboard? Did they run down the road, they've never done that before? Where is he?
They don't necessarily make sense.
imo
