A 25-year-old man fell to his death at the Glen Canyon National Recreation Area on Sunday, and when officials went down towards its base to recover the body, found unrelated human remains.

The identifiable victim, identified as Orlando Serrano-Arzola, was taking pictures when he tumbled a total of 250 feet to his death. According to a statement issued by the National Park Service, Serrano-Arzola fell off a 100-foot ridge at first, but slipped down an extra 150 feet towards the bottom. The fall was reported at approximately 9:04 a.m., and his death was confirmed at 9:27 a.m.

A separate statement says that the recovery team found unrelated, unidentified human remains, and states that the Sheriff’s office and National Park Service are conducting an investigation into them.
