So basically they are focused on proving that when Arochi took Christina that was planned, that is to say, premeditated, wholly against her will, and in no way a consequence of some sort of accident?
They don't have to prove negatives that "it wasn't this, it wasn't that." They just have to provide evidence within the time-space-circumstances context that proves she was kidnapped (and if they can prove she was in his trunk, there ya go, because that clearly would have been an act of taking her somewhere against her will) with an aggravating factor also being a part of the equation. It's not as complex an equation legally as some want to make it imo.
I notice that they make no claim that she was dead when he put her in the trunk or that she is dead now. The language is general in that respect.
Correct. That distinction (of whether she is currently alive or dead) would be irrelevant to the charge of whether he kidnapped her on or about Aug 30 2014.
