The sheriff’s investigation into Chase Andrews’s death changes the apparent story of an accident into a case of suspected murder. At the fire tower, Ed Jackson and Joe Purdue find a body beneath an open grate but no trail showing how Chase reached the platform. The absence of ordinary traces becomes the investigation’s central evidence: the scene looks less like a fall that happened by chance than one arranged to resemble one.

The Scene and the Missing Tracks

The first discrepancy appears in the muddy ground between the tower stairs and Chase’s body. Ed points out that the boys’ footprints lead from the staircase across the bog to within eight feet of Chase; they stopped when they recognized him and backed away. Their tracks are plainly visible, but no fresh prints circle the body, approach it, or lead toward or away from the stairs. Ed reasons that people who had been with Chase would likely have hurried to him after a fall, leaving tracks as they checked whether he was alive. The untouched mud therefore contradicts the idea that companions were present at the moment of death.

The possibility that Chase had been alone does not resolve the more basic absence. If he had walked along the path, crossed the mud, and climbed the stairs, he should have left his own footprints. Ed asks how Chase could have reached the tower without making them. At this stage, the investigation has not established what happened, but it has identified a physical gap between the supposed route and the evidence on the ground.

Ed initially acknowledges that, on the surface, the scene resembles an accident: Chase could have fallen from the tower and been killed. He and Joe search the area for ten minutes, finding no additional prints and no sign that anyone had brushed tracks away. The search does not turn absence into proof of a particular suspect or method; it narrows the question to whether the missing traces were never made, were removed, or were avoided by some other means.

The Open Grate and the Accident Theory

The tower’s platform provides a possible explanation for how a fatal fall could have occurred. Its center is made of old wooden planks, while square grates around the perimeter can be opened and closed. When shut, the grates form a walkable floor; when one is left open, a person can fall about sixty feet to the ground. On reaching the platform, Ed and Joe find one of these grates open. Beneath it, Chase’s body has left a distinct outline in the mud, with yellowish material and duckweed splashed around the impact site.

Ed notes that a grate over the stairs is sometimes left open when people forget to close it as they descend, but the other grates are almost never open. That distinction makes the opening over Chase’s impact position difficult to dismiss as ordinary forgetfulness. Ed proposes that someone may have opened it in preparation for pushing another person to his death, then left it open so the fall would appear accidental. The explanation is a working theory, not yet a complete reconstruction: the investigators still have to account for the missing tracks and determine how the tower was approached.

The sheriff’s desk review deepens rather than closes the evidentiary gap. The time of death is placed between midnight and two in the morning on October 29–30, 1969. Apart from the two boys’ prints as far as the third switchback, there are no fresh fingerprints on the railing or grates—not Chase’s and not anyone else’s. Ed observes that there is no physical evidence that Chase walked across the mud, climbed the stairs, or opened either of the two grates at the top, including the one above the stairs and the one through which he fell. Nor is there evidence that another person did those things.

Negative Evidence and the Homicide Conclusion

The lack of tracks and fingerprints leads Ed to describe the case as one of negative data. It does not show exactly who acted or how, but the pattern makes a routine accident increasingly hard to accept. Ed considers two broad possibilities: someone cleaned the scene unusually thoroughly, or Chase was killed elsewhere and his body was moved to the tower. Joe points out a difficulty with the second possibility: transporting a body by vehicle should have left tire tracks. The men decide to return and search again for tread marks beyond their own and the ambulance’s, acknowledging that an overlooked trace might still alter their understanding.

Even before that renewed search, Ed says he is now confident that Chase’s death was no accident, and Joe agrees. Their conclusion rests on the convergence of absences—the missing footprints, the missing fingerprints, and the lack of a visible attempt to erase the mud—together with the open grate and the body’s position beneath it. The scene seems designed to permit an accidental-fall explanation, yet the expected traces of an ordinary approach to the tower are missing. The investigation’s key turn is therefore not the discovery of a single decisive mark but the recognition that the scene’s silences form a pattern.

Laboratory Findings and a New Trace

Later laboratory findings settle one major question raised by the investigators’ alternative theory. Bruising and internal injuries are consistent with an extensive fall. Chase struck the back of his head on a crossbeam, and the blood and hair on that beam match his samples; the impact caused severe bruising and damage to the posterior lobe but did not itself kill him. The reported cause of death is the sudden impact to the occipital and parietal region of the posterior cerebral cortex, together with a severed spine. The findings support the conclusion that he died from the fall and, because matching blood and hair remain on the tower’s crossbeam, that he died where he was found rather than having been killed elsewhere and moved.

The laboratory report also adds a tangible clue without identifying its source. It finds numerous foreign fibers on Chase’s jacket, including red wool fibers that did not come from his own clothes. Ed holds up the sample in a small plastic bag. Joe lists several possible kinds of garment—among them a sweater, scarf, hat, shirt, skirt, socks, or cape—but the evidence does not establish which one supplied the fibers or who wore it. Ed’s immediate task is to find the source. The fibers thus give the inquiry a new material lead, while leaving the larger problem intact: the laboratory clarifies where and how Chase died, but the missing traces at the scene still point toward deliberate concealment.
