Yellowstone National Park announced Thursday that the human foot found in Abyss Pool, located in the West Thumb Geyser Basin, belonged to a 70-year-old man from Los Angeles, California. Yellowstone law enforcement officers received the positive identification of Il Hun Ro based on DNA analysis in the last three weeks and notified the family.

In August, staff discovered part of a foot in a shoe floating in the well-known thermal feature and an investigation led by Yellowstone law enforcement officers began. The investigation determined, to the best of our knowledge, that an unwitnessed incident involving one individual happened on the morning of July 31 at Abyss Pool, and no foul play occurred. Based on a lack of evidence, the circumstances surrounding the death of Ro remain unknown.

This investigation has concluded, and the park has no additional information to share.

Yellowstone would like to thank the NPS Investigative Services Branch, Teton County Coroner’s Office, Teton County Search and Rescue, and Wyoming Division of Criminal Investigation for their assistance in the investigation.
