As night falls, Grace (right), now abandoned by the rest of her family, remains with Eleanor, trying to nudge the sickly elephant to her feet. Grace stays with her for another hour, but Eleanor is unable to stand, and Grace leaves.
By this time Eleanor's family is already about a mile (1.5 kilometers) away, moving away from the river, as elephants typically do at nightfall.
"As Eleanor became sick," zoologist Iain Douglas-Hamilton said, "she lagged behind the rest of the family. They would normally expect her to keep up or lead the group. So we assume her own family did not know of or witness her collapse."
