A 3-year-old Idaho girl who shot and killed herself in Yellowstone National Park over the weekend has been identified as Ella Marie Tucker of Pocatello. Authorities said they still don't know how she got the gun.
Park officials said the shooting remained under investigation and they did not release the girl's parents' names or further details of what happened, the Associated Press reported.
Park officials say the girl's mother called for help on Saturday to report her daughter had shot herself with a handgun. Park rangers who responded to Grant Village Campground on the western shore of Yellowstone Lake were unable to resuscitate her.
