If you are looking for something that will show when something is not there anymore or is destroyed, I think this will be what you are looking for:

public SpriteRenderer notFound;
// This is for showing and hiding the not found message
public GameObject target;
//GameObject that you want to check if it is there

void Update{
if(target == null){
notFound.enabled = true;
} else
{
notFound.enabled = false;
}
}
