Aaron Michael Pate was 17 years old when the male teenager disappeared in 1992. The National Center for Missing & Exploited Children currently lists him as missing since March 16, 1992, from Grand Canyon, Arizona, although other established case records describe him as having been last seen in his hometown of Keota, Iowa, before traveling west and eventually reaching the Grand Canyon area.
That difference in the public record has followed Aaron’s case for years and appears to reflect the unusual way his disappearance unfolded rather than a single, clearly documented moment when he vanished. Aaron was described as approximately six feet to six feet two inches tall and about 145 pounds, with brown hair and brown eyes. He had several distinguishing characteristics that could help identify him, including a one-inch scar on his right wrist, moles on his back, a pierced left ear, and eyeglasses.
Aaron had been living in Keota, a small community in southeastern Iowa, before the events that ultimately carried him hundreds of miles from home. Investigators have classified the case as an endangered runaway, and published accounts say police believed Aaron had voluntarily left the area. Shortly before he disappeared, authorities believed he had taken a vehicle that was later found abandoned along the Kewash Nature Trail. No trace of Aaron was found with the vehicle. Family information later provided publicly by his brother, Ian Pate, added another important piece to the story: Aaron reportedly left home in a family car, which was eventually located in the Iowa City Public Library parking lot and towed after accumulating parking violations. A Greyhound bus station was located nearby, leading the family to believe Aaron may have continued his journey by bus and then by hitchhiking. His apparent destination was Arizona, where his estranged father, Randall Pate, was living. According to his brother, Aaron had met his father only twice before, making the journey a significant and uncertain step for a teenager traveling largely on his own.
The circumstances became more complicated because Aaron was not formally entered as a missing person until April 30, 1993, more than a year after the date associated with the beginning of his disappearance. His brother later stated that law enforcement had been aware that Aaron could not be located during the earlier period because officers had been looking for him in connection with the vehicle incident. Whatever administrative decisions were made at the time, the delay meant that the crucial first months of Aaron’s travels passed without the kind of widespread missing-person investigation that might normally follow the disappearance of a teenager. Published case records describe Aaron as someone who did not have an established history of serious trouble, and people familiar with him remembered a quiet, friendly young man. His departure therefore left his family with the difficult task of trying to reconstruct where he went, whom he met, and how he traveled after leaving Iowa.
Years later, Aaron’s family obtained information that significantly changed the understanding of the case. Ian Pate reported that he eventually made contact with their father, Randall Pate. According to Ian’s public account, Randall confirmed that Aaron had in fact reached Arizona and had visited him in the Grand Canyon area several months after leaving Iowa. That account provided the family with something they had lacked for decades: confirmation from a person who said he had actually seen Aaron after Aaron began traveling west. Randall reportedly appeared surprised when told that Aaron had subsequently been considered missing. He also told Ian that Aaron had left Arizona intending to meet a girl in Boulder, Colorado. Publicly available information does not identify that girl, explain how Aaron knew her, or establish whether Aaron ever reached Boulder. That unidentified person and Aaron’s intended journey toward Colorado consequently represent one of the most important unresolved portions of his known movements.
The later account from Aaron’s father also helps explain why some databases identify Grand Canyon, Arizona, as the place from which Aaron disappeared while others continue to associate the case with Keota, Iowa. The Iowa records focus on where Aaron’s journey began and list March 16, 1992, as the date he was last seen, while the National Center for Missing & Exploited Children lists Grand Canyon as the missing location. Family information indicates that Aaron traveled across several states after leaving Iowa and ultimately did reach his father in Arizona, meaning there was apparently a period during which Aaron was moving independently and was not simply absent without any contact or destination. The exact chronology of that journey is not consistently documented in the major public databases, and the available records do not establish precisely when Aaron left his father, what transportation he used afterward, or whether anyone reliably encountered him after he headed toward Colorado.
As the years passed, Aaron’s family continued trying to find answers, particularly about his time in Arizona and what happened after he left the Grand Canyon area. His brother publicly expressed frustration that he believed investigators had not obtained enough information from their father about Aaron’s final known movements. The Keokuk County Sheriff’s Office has remained associated with the case, and the National Center for Missing & Exploited Children continues to circulate Aaron’s information and an age-progressed image. The case is identified by NamUs number 6499 and NCMEC number 772107. Taken as a whole, Aaron Pate’s story is not simply that of a teenager who disappeared from one location on one day: it is the story of a young man who left rural Iowa, apparently traveled by a combination of transportation methods across the country, reached the Grand Canyon area to reconnect with an estranged father, and reportedly planned another journey toward Boulder, Colorado. The unanswered question begins after that final known chapter—somewhere between his confirmed presence in Arizona and whatever journey he intended to make next, the trail of reliable information about Aaron came to an end, leaving his family with decades of uncertainty about where he went and what happened to him.Last Seen: Mar 16, 1992
