Couple things. First, it's been mentioned a couple of times that maybe the alleged kidnapper shot Rita when he heard the phone ring and the officer was calling. That doesn't make sense to me. It sounds like the shots happened so fast after the phone picked up, that I can't see the alleged kidnapper having time to pull over, pop the trunk, walk to the back of the car and then fire 2 shots. This sounds like it happened immediately when the call was picked up. The only way that is possible is if the kidnapper had already pulled over and gotten out and was headed toward the trunk, which he would have already had to pop open. Then, fire 2 shots.
Also, if the reason for shooting her at that point was because the phone rang then why didn't he shoot her at any of the times the phone rang previously or she was making calls. From what I can tell, there were several phones to and from the phone; between Rita and her family, as well as the police. Surely the kidnapper would've heard those previous phone rings and calls?
Also, I have an issue with the timeline. I haven't seen this mentioned, but maybe I missed it. Anyways, the first use of the debit card was in Kingston, ID, at 4:15pm, right? Then, the next thing we have is the car being picked up on a highway video camera at 9pm in Post Falls, ID.
Well, Google maps tells me that Kingston and Post Falls are only 43.1 miles apart and the drive from Point A to Point B would take 42 minutes. Except, the car is at Point A at 4:15pm and not at Point B until 9pm. That's 4 hours and 45 minutes, for what would be about a 45 minute ride. So, what's going on in the 'missing' 4 hours? Where did the car go between 4:15pm and when it showed up on the camera at 9pm? If it was a kidnapper, somehow I doubt they would be hanging around the gas station for any longer than they had to.
I don't know, for me, that 4 hours is a something that I'm hung up on. It makes no sense, especially if it was a kidnapper. Now, if it was a person who was conflicted about harming themselves and just driving around trying to think, then that makes more sense. I don't know. I just thought I would mention the 4 hours because I haven't seen it discussed anywhere.
Of course it bothers me, too that the car traveled to Ritzville, past Spokane, got gas, and then turned around and went back to Spokane. Why would it matter to a kidnapper where he ditched the car? And why would he go past Spokane then turn around and go back? Even if he didn't know that Rita was making phone calls, he surely would have figured that someone might have noticed she was missing and called police, and that police could be out looking for the car. Why not just dump the car in Ritzville somewhere? If seems like the person who drove the car had some idea of where they were going, at least with regards to familiarity of the areas.
ETA: When you consider the car stopped for gas again in Ritzville, it seems even more illogical to me that the car would then go back to Spokane. Why would a kidnapper shell out another $25 to buy enough gas to go back to Spokane, instead of just ditching the car somewhere in Ritzville? Even though the money was taken from Rita's card and he didn't pay for it, why take the chance of going to a second gas station when it wasn't necessary? Any why put in $25 instead of say $10? Ritzville to Spokane seems to be only 60 miles. Putting $25 in makes me think someone was putting in at least half a tank and was planning to drive around some more. For a kidnapper who is trying to avoid being caught, that doesn't make sense. For a conflicted person trying to decide what to do, it makes a lot more sense.
The parking lot where she was found was somewhat close to Spokane Airport, wasn't it? If it was suicide that would make sense to me, because she might think the police would believe the kidnapper hopped a plane out of the city and no one could ever be prosecuted or even found.
