For any species there is a minimum viable population, the smallest possible size of a biological group that can exist without becoming extinct. For terrestrial vertebrates this would be in the thousands.As the creatures go above ground to hunt in the day time (and there is no reason why they would also not go in great numbers, having no fear of people or even bears), it is inconceivable that they would not have been noticed, or even photographed, by large numbers of people.
