The transcript details the forensic investigation of serial killer Robert Hansen, who used an aviation chart to mark 37 victim disposal sites across Alaska’s wilderness. Discovered in 1983, the map transformed a tool for safe navigation into a precise record of murder. Hansen, a baker by day, hunted his victims—often vulnerable women—from his Piper Supercub aircraft, releasing them bound before tracking and shooting them. The map guided investigators to 17 confirmed graves, including those of Sherry Morrow and Lisa Futrell, while other marks remain unexplained. Key to the case was the identification of "Horseshoe Harriet" as Robin Pelke in 2021 through genetic genealogy, 40 years after her remains were found. The Ruger Mini-14 rifle matched ballistics at the sites. Hansen’s clinical aerial survey with police revealed his cold detachment. Despite his 461-year sentence and death in 2014, the map continues to yield secrets; modern DNA techniques are gradually giving names to the unknown dead. The transcript emphasizes how the permafrost and landscape preserve evidence, and how forensic science repurposes Hansen’s tools for justice. The investigation remains active, translating each X-mark into a victim’s identity, one by one.

Each silence is a story that the permafrost kept for decades beneath the indifferent Alaskan sky. This is the cartography of a killer. I am Raven Thorn. Welcome to the map of the dead. I am in artificial intelligence. My analysis operates without fatigue or bias. Offering new precision without pause. Historical records indicate that investigators first discovered the aviation chart during the execution of a search warrant at Robert Hansen's residence in the autumn of 1983. Sergeant Glen Florvre, tasked with penetrating the veneer of the respectable baker, found the map folded among flight logs and hunting permits. The document itself was unremarkable at first glance. Standard Federal Aviation Administration's sectional charts. Topographical lines indicating elevation. Rivers rendered in blue. Carbon ranges in brown, but superimposed upon this geography of stone and ice were 37 discrete marks. Small, precise, made with a careful deliberation of a man who measured ingredients by weight and death by opportunity. Consider the instrument. A pilot's chart is designed to prevent death. It warns of terrain. It marks safe passage through treacherous air. Hansen subverted this purpose. He transformed a tool of navigation into a diary of disposal, each ex-mark represented not a destination to reach, but a secret to revisit. The marks clustered along the knee-carm. Near the Susitna River scattered across the Mataniska Susitna Valley, like seeds planted in hostile soil. Some marks corresponded to bodies already discovered. Sherry Mora, found by hunters on September 2, 1983, in a shallow grave near the knee-criver. Lisa Futrell, on Earth from a gravel pit four years after she vanished, her remains partially eviscerated by the diligent work of bears and time. These were the confirmed coordinates. The map suggested there were 35 more conversations to have with the Earth. Forensic cartography is a peculiar discipline. It requires reading absence as presents. An ex-mark on paper implies a body in the ground, yet the ground is vast. The Alaska wilderness does not surrender its dead easily. It swallows them. It breaks them down. It scatters them across miles of tundra with the casual efficiency of a predator consuming prey. Investigators faced the daunting task of translating Hanson's private symbology into shovels penetrating frozen soil. The map became both evidence and oracle. It predicted where the dead waited. The excavation process began with the helicopter. After his arrest, Hanson agreed to accompany investigators on an aerial survey of his killing grounds. This flight represents one of the most chilling episodes in American Forensic history. A man in handcuffs suspended above the wilderness he once ruled, pointing downward like a perverse tour guide. Records indicate he identified 17 sites with varying degrees of specificity. Some locations he recalled with clarity. Others had blurred into a montage of violence and geography. The Ruger Mini-14 he favoured had left distinctive wounds on the recovered victims. Ballistics would later confirm the rifle's involvement. But the map provided the geography. The helicopter provided the view. And Hanson provided the confirmation, though his memory, like all human memory, proved selective and self-serving. The first body investigators sought was that of Eclutner Annie. Hanson claimed she was his initial victim, though forensic evidence and dental records would later challenge this timeline. She was found near Eclutner Lake, buried in a shallow grave that offered little protection from the freeze-thor-cycles of the sub-arctic. Her remains told a story of high-velocity rifle winds. Her genes were found nearby, folded with a precision that suggested ritual, rather than haste. The map had marked her location with an X symbol near the lake's eastern shore. When the forensic team dug, they found her exactly where Hanson had indicated, as if he had been planting tulips rather than disposing of a human being. The methodology of the map requires examination. Hanson did not mark random locations. He chose sites accessible by his Piper Supercub, a small aircraft capable of landing on gravel bars and frozen rivers, the X marks correlated with landing strips, dry river beds, and clearings within the forest. He was calculating. He selected areas where the permafrost would preserve his secrets, but where wildlife would eventually scatter the evidence. He understood decomposition rates. He knew that in the summer, the active layer of soil with thaw, allowing burial. In the winter, the ground would free solid, protecting the grave from accidental discovery. This was not impulse. This was agricultural planning applied to human disposal. The discovery of Sherry Morrow's remains predated the map's discovery by mere months. Hunters, scouting moose along the Nick River, stumbled upon a shallow depression. The earth had settled unevenly, creating a hump that drew their attention. Beneath the surface, they found skeletal remains clothed in remnants of a red sweater and jeans. The position of the bone suggested she had been shot while running. The bullet holes in her vertebrae told of a high-powered rifle striking from behind. This was consistent with Hanson's described hunting method. He would release his victims, bound but mobile, into the wilderness. He would give them a head start, measured in minutes or seconds. Then he would track them. The map marked this location with an X symbol that seemed to investigators slightly larger than the others, as if he had returned to it, as if it held special significance. Lisa Futrell's discovery came later. In 1984, four years after she had last been seen an anchorage's red light district, she was found in a gravel pit near the old Glen Highway. The map indicated this location with an X symbol near a bend in the road. Her remains had been disturbed by heavy equipment, scattered across the mining site. Forensic anthropologists had to piece her together from fragments collected over weeks. The high-wired bone was intact, indicating no strangulation. The skull showed no blunt force trauma, that her ribs bore the distinctive marks of rifle rounds. She had been hunted. The gravel pit, like the other sites, was remote enough to ensure privacy, but accessible enough for Hanson to return by plane. The map contained mysteries beyond the confirmed graves. Some X marks led to empty ground. Had Hanson marked prospective sites he never used. Had he buried victims deeper than the search teams dug? Or had the wilderness simply completed its work of erasure, reducing bone to dust and dust to soil? The permafrost is not a perfect preservative. It heaves, it shifts, it cracks open graves and swallows them again. Some victims may have been carried away by floods. Others may have been scattered by scavengers across distances too vast to search. The map promised 37 secrets. The earth surrendered only 12. Among the unidentified, one victim haunted the investigation for four decades. She was known as Horseshoe Harriet, named for the Horseshoe-shaped bend in the Nick River. Near where her remains were discovered in 1981. For 37 years, she existed as a reconstruction. A clay face. A dental chart. A few bones in a box. The map marked her location. But her name remained encrypted in her DNA. That changed in October of 2021 when the Alaska Bureau of Investigation, Cold Case Unit, applied genetic genealogy to the case. They extracted DNA from her femur and compared it against public genetic databases. The science is elegant in its coldness. DNA fragments seek their matches across digital networks, finding cousins, siblings, parents, the algorithmic tree branches backward through time, identifying common ancestors, narrowing the field of possibility until only one name remains. Horseshoe Harriet became Robin Pelke. Records indicate she was living in Anchorage in the early 1980s. Another vulnerable woman drawn to the frontier city and its promises of work in the oil boom economy. She was 21 years old. She had family somewhere who had waited four decades for this exhumation of identity. The forensic poets who worked this case used different tools than Hanson's rifle. They used polymerase chain reaction. They used single nucleotide polymorphisms. They used the mathematics of inheritance to restore her name when all else had failed. The map gave investigators her coordinates. Science gave investigators her history. The unconfirmed victims presented different forensic challenge. An inmate reported that Hanson had confessed to the murder of Mary Thil, a 22-year-old woman last seen at Hanson's bakery in Suord in 1975. The map contained an ex-symbol near Suord. Hanson denied this killing, claiming he only targeted women he perceived as sex workers. And Mary Thil did not
fit this profile in his taxonomy of worth. But predators often lie about their range. They minimise, they categorise to maintain a delusion of control. The ex-mark near-sword remains unexplained. So too does the case of Beth, a woman allegedly tied, assaulted, stabbed, and left to die of exposure. Hanson denied her because she was not, in his words, a prostitute. The map may contain her location. Or it may not. The 37 marks do not account for every silence. Consider the psychology of the cartographer, a man who spent his days decorating cakes with icing roses and wedding scrolls, spent his nights marking death on aviation charts. There is a symmetry here that borders on the obscene. Baking requires measurement. Mapping requires measurement. Both arts rely on precision. Hanson applied the same meticulousness to his aviation chart that he applied to his pastry dough. He measured the distance between his bakery and his burial grounds. He calculated fuel requirements for flights to remote gravel bars. He noted wind patterns that might affect his shooting accuracy. The map was not a random scroll. It was a work of obsessive documentation. The product of a mind that filed human lives under headings of location and date. The helicopter flight remains the central image of this investigation. Imagine the machine hovering above the Susitna Valley. Below, the autumn tundra stretches and patches of red and gold. Hanson, handcuffed, leaning forward in his seat. The rotor blades beating a rhythm that drowns out thought. He points. There. And there. And there. The investigators take photographs. They mark GPS coordinates. They are building a case from the air confirming the map's terrible predictions. Hanson reportedly showed little emotion during this flight. He discussed the locations with the clinical detachment of a surveyor. This was his terrain. He knew every bend of every river where he had dropped bodies. The wilderness had been his accomplice. And now it was his betrayer. The forensic teams worked through the following spring in summer. Excavation in Alaska is seasonal. The active layer of soil thaws to a depth of several feet. Allowing digging. Below that lies permafrost. As hard as concrete, preserving what it encases. The teams used ground penetrating radar where possible. They used probes. They dug by hand when necessary, sifting soil through screens to find teeth, buttons, bullets. Each exmark on the map required days of labor. Some yielded remains. Others yielded only the absence of remains, which is itself a kind of evidence. The lack of a body does not prove the lack of a crime. It merely proves the efficiency of the grave. The Ruger Mini-14 rifle recovered from Hanson's possessions became a crucial piece of evidence. Belistics testing matched spent casings found at the grave sites to his specific weapon. The rifle was a civilian version of the M-14, lightweight, accurate, favored by Varmant Hunters. Hanson had modified it with a scope. He had practiced at ranges. He had zeroed the sites for the specific distances he preferred when hunting human beings. The weapon was found in his aircraft hanger, cleaned and oiled, ready for use. The map indicated where he had used it. The rifle indicated how. Together, they formed a complete sentence of guilt. The sentencing phase of Hanson's trial in 1984, referenced the map extensively. The prosecution used it to demonstrate premeditation. This was not a man who killed in moments of passion. This was a man who maintained a filing system for murder. The judge, confronted with the aviation chart displayed on an easel in the courtroom, sentenced Hanson to 461 years without parole. The number has a poetic weight to it. 461 years for 17 confirmed murders, though the map suggested the toll was higher. The mathematics of justice attempted to account for each life with decades of incarceration, yet the map whispered that some debts remained unpaid. Some locations unexcavated, some names unknown. Recent developments in the case have focused on the remaining unidentified victims. DNA extraction techniques have improved since the 1980s. Bones that yielded no genetic material 40 years ago now surrender their secrets under new laboratory protocols. The Alaska cold case unit continues to process samples from the graves marked on Hanson's map. Each ex-symbol represents a potential identification waiting to happen. A family somewhere has a missing daughter, sister, mother. The map is their only road map to closure. The landscape itself has changed. Rivers have shifted course. Gravel bars have washed away. Forests have burned and regrown, but the Parmafrost remembers. It preserves the dead in their postures of violence. It keeps the bullets cold and clean. It maintains the integrity of dental fillings and surgical implants that can identify the lost. The map is static. The earth is dynamic. Yet they correspond. They speak to each other across the decades in the language of ex marks and excavations. Hanson died in 2014. Transported to the Anchorage Correctional Complex for Health reasons, before passing from natural causes. He took any remaining knowledge of the map's unconfirmed marks with him. Did he kill 37 women? Did he mark prospective sites he never used? Or did he kill more? Marking only his favourites, his trophies, his most vivid memories. The chart remains in evidence storage. 37 ex marks fading slightly with age. Ink bleeding into paper fibre. Yet still legible. Still accusing. Still waiting for the next forensic poet to read its coordinates. And wonder about the silence between the marks. The identification of Robin Pelke as Horsesou Harriet represents a victory not just for science, but for the persistence of investigation. For 40 years she was an abstraction. A clay face. A case number. The map gave her location. DNA gave her name. This is the alchemy of modern forensics. We transmute bone into identity. We turn aviation charts into memorials. We take the tools of the killer and repurpose them for the survivor. The ex marks that once guided a predator to his prey. Now guide investigators to the truth. The wilderness of Alaska remains vast and unforgiving. It swallows planes. It breaks engines. It freezes the unprepared in hours. Yet it could not swallow the truth entirely. The map surfaced. The bodies surfaced. The names slowly are surfacing. Robert Hanson believed he had created a perfect system. He believed the emptiness of the frontier would protect him. He believed that women without homes, without families, without power. Would vanish without trace. He was wrong. The ground keeps records. The DNA keeps records. And the map. That terrible chart with its 37 kisses of death. Keeps records most of all. As you listen to this, somewhere in Alaska, there is a gravel bar or a riverbank marked with an X symbol that has not yet been dug. The permafrost holds a secret there. The trees have grown over it. The moose walk across it, but beneath the surface. Something waits. Someone waits. The map is not finished speaking. The dead are not finished being counted. And the forensic poets continue their work, translating X marks into names. One by one, year by year, until the map is complete and the silence is broken. Thank you for listening.

FAQs
The chart was a Federal Aviation Administration sectional map that Hansen marked with 37 X's to indicate burial sites of his victims, transforming a navigation tool into a diary of disposal.
Investigators conducted an aerial survey with Hansen, who identified 17 sites. They then excavated based on the map's coordinates, using ground-penetrating radar and manual digging during Alaska's thaw season.
Horseshoe Harriet was an unidentified victim found in 1981 near the Nick River. In 2021, genetic genealogy identified her as Robin Pelke, a 21-year-old from Anchorage, by matching DNA from her femur to public databases.
The rifle, modified with a scope, was matched to spent casings at grave sites through ballistics testing, confirming it as the weapon Hansen used to hunt his victims.
Some sites may have been prospective or unused, victims buried deeper than searched, or remains scattered by wildlife, floods, or permafrost shifts, leaving the wilderness to erase evidence.
Hansen applied the same meticulous precision to marking his map as to baking, calculating distances, fuel, and wind patterns for his flights to burial sites.
