I have been thinking about this as well. It seems that until she was picked up on the warrant and questions within 24 hours of the incident (per the previously posted Affidavit and Application for Arrest Warrant), KA only confirmed a general understanding that a woman in the "cycling community" had been killed. (I don't think the story had hit the news by the 12th so how she knew that would be from limited sources and likely CS and the police appearance at the home.) So if KA was in fact the responsible person for the shooting, then she may have remained under the belief she had successfully made it appear as a robbery as of her questioning on the 12th, right? At that point, it stands to reason she likely would have returned the gun to make it appear as if it never left. While CS was being questioned at the stating, again per the warrant, the search warrant was executed and the gun was retrieved. May have been no chance to get rid of it after she learned the ruse was up if that was in fact what she was up to. All three events appear concurrent or very proximate in the Affidavit - the questioning of CS, the search of the residence and the apprehension and questioning of KA. It does seem like there may have been a little time between CS being first engaged at his home and the execution of the (apparently invalid) warrant as to KA but by then, it would really highlight potential guilt and create great risk to dispose of the gun, right? Obviously there remains speculation here but it does beg the question as to what was happening with KA from her release on the 12th and her leaving on the 14th headed to NYC. Moreover, even if planned ahead of time, the thought KA may have "planned" an exit ahead of time as a contingency plan to leave the Austin area is kind of thwarted when one considers she returned the gun to the home. If KA did indeed do this and it was so well thought out, wouldn't getting rid of the gun immediately be the only option if it was used in the incident? By the time they got to the point of searching their home, if it was used, it would have been connected and her plan to take off would happen anyway. These known facts seem to point to the idea that if she did in fact do this, it seems less likely it was thoroughly planned out ahead of time and KA was reacting as things became known.
