YELLOWSTONE NATIONAL PARK - Newly released law enforcement reports shed some new light on a human foot found in a hot spring in Yellowstone National Park.
The remains of Il-Hun-Ro, a 70-year-old from Los Angeles were found in the Abyss Pool last summer.
The pool is part of the West Thumb Geyser Basin.
The documents say a park visitor noticed a shoe in the pool and told a tour driver who then notified a park ranger.
Ro was identified using DNA from the foot and a relative.
Documents found in his vehicle also helped in the identification.
That vehicle, a compact SUV, was the last one left in the parking lot after the area was evacuated.
Investigators say no suicide note was found among Ro's belongings.
