Euler discovered that if you make more entrances than exits, you will be stuck there! In the crime fiction novel Presumed Dead, the crime reconstruction is solved using this insight. How smart is that? https://wp.me/P1z4yo-n
Many crime fiction stories are solved by luck, by coincidence, by interrogation and by confession. These are not often available in investigation of real crimes and the CI has to rely on search for evidence and analysis. This can be haphazard or systematic and efficient. In the political crime fiction novel Presumed Dead, the CI follows an Euler Walk to reconstruct the crime efficiently. The method could be widely used, even by other crime fiction writers.
Inductive method of psychological profiling
The premise is that if certain crimes committed by different people are similar, then the offenders could have similar personality traits.
This method is slightly different. From a thorough analysis of the crime scene and the evidence left at that scene, the profiler is able to construct a mental picture of the unknown offender. Information about the victim is crucial, for the more one knows about the victim, the more one knows about the offender. In the crime fiction novel Presumed Dead, the investigation employs both methods at different stages.
Direct evidenceof an occurrence is perceived by a witness using their senses.For example: a witness who testifies that he saw the defendant shoot the victim.
Indirect evidenceestablishes immediately collateral facts from which the main fact may be inferred e.g. Caltech astronomers Mike Brown and Konstantin Batygin have accumulated indirect evidence for an object that’s more than twice the diameter of Earth, but 10 times as far from the sun as Pluto.
Circumstantial evidenceconsists of a fact or set of facts which, if proven, will support the creation of an inference that the matter asserted is true e.g. a fingerprint at the scene of a crime.
In the crime fiction novel Presumed Dead, evidence of these types is used to reconstruct the crime.
