Why wasn't Mosler stolen?Devil's advocate here. If a car enthusiast/wanna be car thief is in on the crime, wouldn't he know the Mosler won't operate without a code? Wouldn't he bring the device to bypass so could turn on ignition? BBC produced a video to show how and everyone up in arms because London known for high level of high end car theft. Second, SS would have given the key up, given the code. There's also a system for making a key that involves programming a blank.
Back to drawing board. Why wasn't Mosler stolen? Decided too hard to unload it so plan B? Had to beat a hasty retreat? Buyer shows late to find a crowd of onlookers, fire fighters and police?
Because killers goal was to get cash?
