Probably, this is another accident of live burial, this time involving a six-month-old boy in Greenland. He was found together with three female mummies and another young boy. All of them were preserved by the icy climate. The little boy could have had Down's syndrome and that he may have been placed in the grave alive with his dead mother, as was the Eskimo custom of the time. The bodies in the cold rock tomb have been dated to 1460 CE.
