Did anybody ever figure out what Cook was doing there? I seem to remember reading that she was a little goofy, and maybe on meds or drugs - - not that any of that means she deserved to be shot. But it has never been clear to me how she ended up in a bad situation where the worst could (and did) happen.
AFAIK, no one knows accept Cook; her husband died not long after her murder, so if he had any inkling, it probably died with him. I have read nothing that suggested she was on meds or drugs.
If I were to guess, she was either calling someone, or was just waiting for something and read a book or listened to the radio. This probably covers 90% of all possibilities, leaving the remaining 10% to bird-watching, or to taking some aspirin, or to checking the map, or to some other, not exceptionally likely, activity.
I've pulled off the road into a parking lot to make a call. I live in a small town, so I wouldn't think twice about pulling into the school parking lot to do so. Well.........until now.
Traffic in Culpeper is gridlock all day long. I used to stop by Baby Jim's when I'd head down that way, but no more. If she wasn't making a phone call, I'll bet the traffic had something to do with her pulling over and his rage.
