Regarding the robbery charge-I have mentioned on here before that I was the victim of an abduction/sexual assault. One of the charges the perp faced in my case, among others, was aggravated robbery. The AR charge was based solely on the fact that they found my bra in the garbage can at his residence. The legal reasoning was that 1.) He forced me to remove the bra by force (in commission of the sexual assault) and 2.) It was in his possession (even though he tried to discard it)
That charge was dropped pretty early on, IIRC because it would have violated the double jeopardy rule. We will probably see the same thing happen in this case-along with many of the other charges (AS certainly cannot be convicted of 4 murder counts for the same victim, for example) but from a legal standpoint, prosecutors want to stick anything and everything they can get for him early on because it is more difficult to tack on additional charges after the arraignment (not to mention it will slow down the judicial process)
I don't believe that the robbery charge shouldn't be interpreted as anything more than the facts show Austin Sigg forcibly removed Jessica's backpack at some point during the commission of the kidnapping/sexual assault/murder, and at one point had her property unlawfully in his possession.
Hope that makes sense
ETA-Also in my case, the perp was charged with 2 charges of unlawful restraint/kidnapping- One for not allowing me to leave his vehicle, and one for taking me to a separate location. I see that Sigg also has 2 charges of kidnapping.
That tells me he did NOT kill her right there in his car, as he has claimed (not that I ever believed him in the first place :furious
but took her to a second location, where he killed her
Also just want to make it clear I'm not bringing this up to get anyone's sympathy, just to help some of this legalese make a bit more sense
