Summary based on the NamUs case record (MP554) and 14 other sources
In the spring of 2005, a 45-year-old man named Daniel Patrick DeSimone vanished from the vicinity of Pahoa on the Big Island of Hawaii. Known to his loved ones as Danny, he was a resident of Nanawale Estates in the Puna district. On the morning of his disappearance, he left his home around 10:00 a.m. He was last seen later that afternoon, sometime between 3:00 and 4:00 p.m., in the downtown area of Pahoa. Daniel, who has autism and is described as mentally handicapped, was known to enjoy collecting cans and bottles from roadsides, and several local merchants reported seeing him that day as they gave him cans. He was approximately 5'8' to 5'9' tall and weighed around 170 to 180 pounds, with brown, balding hair and blue eyes. A notable distinguishing feature was a horseshoe-shaped scar on his nose.

The circumstances surrounding Daniel's disappearance remain unclear. There are differing accounts regarding his reason for leaving home on that particular day. One report suggests he left to collect cans to redeem for cash, a familiar activity for him. However, another account indicates he may have left after an argument with his brother. It was considered unusual for him to leave without some of his prized possessions, including a fanny pack he reportedly carried everywhere. Concerns for his well-being were heightened due to his medical condition, which rendered him incapable of caring for himself. The days turned into weeks, and despite efforts to locate him, he has not been heard from since.

In the months following his disappearance, there were potential but unconfirmed sightings of Daniel on the island of Kauai. The investigation into his whereabouts has been handled by the Hawaii Police Department. The case remains unsolved, leaving a void of uncertainty for those who knew him. The disappearance of Daniel DeSimone is a long-standing mystery in the community, a poignant reminder of a vulnerable individual who seemingly vanished without a trace from the streets of Pahoa. The lack of concrete leads or confirmed sightings has left his case open and the circumstances of what happened to him unknown.
