Final answer:
A completely skeletonized human body found unburied suggests that significant time has passed since death and there may not have been a formal burial.
Step-by-step explanation:
When investigators find a completely skeletonized human body in the woods that is unburied, they can deduce several details about the remains. Firstly, since the body is completely skeletonized, one can infer that a significant amount of time has passed since the individual's death, as the process of decomposition has run its course to the point where only the bones remain. Secondly, the absence of burial suggests that this may not have been a formal death scenario, such as a recognized funeral, and could entail other circumstances such as crime, casualty of nature, or an unattended solitary death.
