On May 10, 1967, thirteen-year-old Joel “Joey” Hoag, a male child from Hannibal, Missouri, disappeared from the south side of Hannibal with his eleven-year-old brother William “Billy” Hoag and their fourteen-year-old friend Edwin “Craig” Dowell. The boys were last seen in the late afternoon, with available accounts placing the sighting between about 4:20 and 5:00 p.m., and other reporting describing the time as approximately 5:15 p.m.
They were believed to be heading toward Murphy’s Cave, an area near a Highway 79 construction project where blasting and roadwork had exposed or opened cave passages that attracted local curiosity. They were reportedly carrying shovels and a flashlight, with some accounts also noting a homemade lantern, the kind of simple equipment that suggested a childhood expedition rather than a planned disappearance.
Joel was remembered as a curious boy, interested in snakes, geology, and exploration. That interest had already caused concern at home: the night before he vanished, Joel and William had reportedly been punished for going to Murphy’s Cave without permission. On the day they disappeared, the Hoag brothers were not supposed to leave their yard, but while their parents were out, they left anyway and joined Craig. The three boys walked into a part of Hannibal shaped by its famous cave country and by the ongoing Highway 79 work, a place where a child’s sense of adventure could meet real danger in the form of unstable ground, hidden openings, construction hazards, and underground spaces that were difficult to search.
When Joel, Billy, and Craig did not return home, the disappearance became one of Hannibal’s most painful mysteries. Searchers focused heavily on Murphy’s Cave and nearby cave systems, and Missouri Life reports that rescuers searched in the cave for nearly a month without finding the boys’ remains. The case has long carried competing possibilities: some believed the boys may have been trapped by a collapse or construction-related cave hazard, while others have questioned whether they were ever inside the cave at all. Later summaries of the case have noted that despite a major search of caves in the area, no trace of the boys or definitive evidence explaining what happened to them was found.
The loss struck not only the families but the broader Hannibal community. Joel and Craig were eighth-graders at Hannibal Junior High, and Joel and Billy came from a large family, leaving behind five brothers and four sisters. Their family owned Hoag’s Tavern, remembered as a popular Main Street restaurant, making the Hoag name familiar in town even before the tragedy. Over time, the boys came to be known collectively as the Lost Boys of Hannibal, a name that reflects both the geography of Mark Twain’s hometown and the aching uncertainty that followed their disappearance. A memorial marker was later placed near the cave area, and a historical marker at Lover’s Leap in Hannibal commemorates Craig Dowell, Joey Hoag, and Billy Hoag as three adventurous boys who explored the hills on May 10, 1967 and were never seen again.
Decades after that spring afternoon, Joel Hoag’s case remains tied to the unanswered fate of his brother and their friend. The available public record does not provide a confirmed resolution, and The Charley Project states that the three boys’ cases remain unsolved. The known story begins with three children leaving the south side of Hannibal for Murphy’s Cave near the Highway 79 construction project, continues through an extensive but unsuccessful search, and rests today in the same sorrowful uncertainty that has followed their families for generations: Joel Hoag was a thirteen-year-old boy last seen alive in Hannibal, Missouri, on May 10, 1967, carrying the tools of a young explorer, and he vanished with Billy Hoag and Craig Dowell into a mystery that has never been conclusively explained.Last Seen: May 10, 1967
