<if indeed he planned to commit the perfect crime.> He DIDN'T!
For some reason that I do not understand, in your replies, what you have completely missed is that, in MY scenario(s), Jim did NOT "plan" to commit the perfect crime. He did not PLAN to commit any crime!
In my most recent scenario, or, IMO, any plausible scenario in which Jim is the perpetrator, I do not think for one moment that Jim had any plan to murder Susanne that night. {Similarly, in my previous scenario, with Jim stabbing her in his apartment, that, too, was sudden, and unplanned.} {{ If Jim is the murderer, given the facts, IMO, it had to occur similarly to the scenarios i presented. Hopefully some of you can present additional scenarios in which the "mechanics of the murder" work as well, or much better. }}
The evolution of this thread, and the excellent discussion of the strengths and weaknesses of several theories and scenarios, is, IMO, working very well in narrowing the possible ways in which the murder could have, and must have, occurred. A very good example of that is whether Suzanne was in a vehicle during part of the +/- 30 minutes.
I may be completely off-base and truly respect the ideas and opinions of other contributors; but, given the FACTS, I would never submit a scenario that includes Jim Van de Veld planning THIS murder. From a mental and intellectual standpoint, Jim Van de Veld would not have ever committed the murder in any manner even resembling the way it occurred. To the contrary, IF Jim, with his intellect, education and training, planned the murder of Suzanne Jovin, or anyone else, it very well might be "the perfect crime." . Think about the Temporary Insanity defense in criminal cases. One of the essential elements is that the crime {technically for other reasons not material here, the criminal action that occurred} was NOT pre-meditated.
Given Jim's life until the time of the murder (or even within a year of it), IF he murdered Suzanne, IMO, it clearly occurred in a manner in which he was "temporarily insane." |
