Emily died from exposure to the harsh winter elements after being assaulted.
In the film “Wind River,” Emily is a young Native American woman whose body is found in the snowy wilderness of the Wind River Indian Reservation in Wyoming. The FBI sends in agent Jane Banner, played by Elizabeth Olsen, to investigate the death, and she teams up with local wildlife officer Cory Lambert, played by Jeremy Renner, who discovered the body. As they delve into the case, it becomes clear that Emily was assaulted and then ran barefoot into the snow, where she eventually succumbed to the cold, dying from pulmonary hemorrhage caused by rapid inhalation of freezing air. The film explores themes of loss, grief, and the challenges faced by law enforcement in investigating crimes on Native American reservations.
