On a Mercedes-Benz door locking mechanism, you cannot simply push the button down and close the door. It won't work. The door lock motor keeps the button from being depressed manually. They are designed this way. The only way to lock it from the outside is with a key in the lock or a remote transmitter that came with the vehicle. IF the authorities should find one or the other missing, then we may have a second party involved and the hunt is on. If all keys and transmitters are accounted for, we have a suicide.
Simlpe deductive reasoning, Watson.
Say,uh, you wouldn't know where he was coming from at that hour, wouldja?
Could this perhaps be a way, if an assailant were to leave via a back door which he opened from the front prior to leaving? Which was then automatically locked when he shut the back door after he got out?
Ahh, but you forgot the Master Key that exists...
For the most part, suicide is an irrational act. But yet, the tin-foilers try to apply criteria as seen through the rational eye. For example, there has been much talk of where the car was when discovered. Is there a "normal" place where such cars are found when there is a suicide? Where? The garage? Right, then people would be saying that the Exec was surprised as he was coming out of his house and getting into his car. What if his car was found 10 miles away? Well, that just proves that he was driven out that far and killed, right?
Propogating these types of theories is better than selling hair growth tonic. I can't wait for the book on why this and the Vince Foster suicide are related.
Sir, you slipping. Certainly your realize that had this been a hit that was tied to the Enron matter, it would not be beyond possibility that keys could be copied or that a second set could be picked up, used and replaced. Keep working at it Holmes. Your seven percent solution is clouding your thinking. Suggest you try it straight for a bit.
