Anything is possible, but I'm still thinking suicide.
So the story is this guy is attacks Rita at a rest stop in the middle of the day. How did he get there? On foot?
And then the carjacker, who mysteriously appeared at a reststop without a car then leaves the stolen car at a remote place outside of Seattle and walks away? The police arrived five minutes after the gunshots. Where did the guy go? Doesn't seem very convenient for him.
And what was the motivation to shoot her? He didn't take her purse, ipad, or gun - just opened the trunk and shot her without the cop hearing any sounds other than gunshots when he was on the phone?
Just the beginning and the ending of the story have unbelievable aspects.
And then there is the middle. The guy is in a stolen car with a woman in the truck with a phone. Even if he didn't know she had a phone, wasn't he worried someone would wonder where she is and call the police? The police then would be looking for the car. He doesn't seem concerned that he could be pulled over at any time but kept the car for hours and hours, traveling on major highways and stopping at a store that had cameras and used her card?
It's possible it's a true story.....but.....I'm thinking it's not true.
