A young girl shot herself to death at Yellowstone Yellowstone National Park on Saturday morning.

According to a statement from the National Park Service, a woman called 911 on Saturday morning and told dispatchers that her daughter had shot herself with a handgun at the Grant Village Campground.

Emergency medical staff attempted resuscitation, but were unsuccessful and the girl later died.

The Park Service said that the girl's identity would not be released until extended family members had been identified. Additional details were expected to be made available on Sunday afternoon.

An investigation was ongoing.

In 2009, Sen. Tom Coburn (R-OK) added an amendment to the Credit Card Accountability Responsibility and Disclosure Act that allowed concealed weapons to be carried in national parks. President Barack Obama signed the Credit CARD Act into law in 2010.
