On May 10, 1967, Edwin Craig Dowell, a 14-year-old male from Hannibal, Missouri, vanished from the south side of the city in the company of two younger boys, brothers Joel “Joey” Hoag, 13, and William “Billy” Hoag, 11. Edwin was known by his middle name, Craig, and contemporary missing-person summaries note that most accounts refer to him that way.
The three boys were last seen between about 4:20 and 5:00 p.m., carrying shovels and a flashlight and saying they were going to explore Murphy’s Cave, a cave near an active Highway 79 construction project.
The setting of the disappearance was painfully ordinary for Hannibal, a river town whose landscape, local lore, and cave systems were part of childhood adventure. Murphy’s Cave had reportedly been opened or exposed by highway construction, and sources describe the boys as exploring the area where State Highway 79 was under construction. Joel and William Hoag had reportedly been punished the night before for going to the cave without permission and were not supposed to leave their yard, but they left while their parents were away. Craig was with them when they headed toward the cave area, and after that afternoon, none of the three children were heard from again.
Because construction work reportedly caused a cave-in at Murphy’s Cave that day, authorities initially believed the boys may have become trapped underground. The search that followed was extensive and urgent, focused on the possibility that the children were alive somewhere in the cave system and unable to escape. Missouri Life later described rescuers searching the cave for nearly a month, with no remains of the boys ever found. Google Books’ summary of John Wingate’s Lost Boys of Hannibal: Inside America’s Largest Cave Search characterizes the effort as the largest cave search in U.S. history, unfolding in Hannibal after the three boys vanished in a complex cave system exposed by highway construction.
The lack of any discovery left families, searchers, and the wider Hannibal community with grief rather than answers. One theory has remained that a collapse sealed the boys inside an inaccessible passage; another view is that they may not have been in the cave at all, because no physical evidence of them was found despite the scale of the search. The Charley Project notes that speculation about other possibilities has persisted precisely because nothing was recovered, but it also states that there is no evidence supporting alternate theories. Craig’s own missing-person profile records his height and weight as unknown, identifies him as a white male, and notes that he lived on Union Street in 1967 and left behind three brothers.
Decades later, the case continued to draw renewed attention whenever new leads or possible cave entrances surfaced. In 2006, construction workers building a new elementary school on Highway 79 found a small cave about 50 feet long, and authorities checked it in case it was connected to the boys’ disappearance, but nothing was found. In 2022, KHQA reported that the Missouri Geological Survey was examining a newly discovered entry near Lover’s Leap, about 40 yards from where the boys were last seen, after a property owner reported it; the effort reflected the continuing hope that even a small physical clue might provide long-denied answers.
Craig Dowell’s disappearance is remembered not as an isolated entry in a missing-person database, but as part of a shared tragedy that forever changed the families of Craig, Joey, and Billy and left Hannibal with one of its most enduring mysteries. A memorial marker was placed near the cave area, and online memorial information describes the three boys as adventurous children who went into the hills of Hannibal and were never seen again, while also recognizing the rescue teams and community members who came from far and wide to search for them. The overview of the case is this: 14-year-old Craig Dowell, male, was last seen in Hannibal, Missouri, on May 10, 1967, with Joel and William Hoag as they headed toward Murphy’s Cave near Highway 79 construction; a major cave search found no trace of them, later searches and new leads have not resolved the mystery, and the case remains a heartbreaking unresolved disappearance centered on three children who left for an afternoon adventure and never came home.Last Seen: May 10, 1967
