Lyle Stevik 1976-2001
6. To establish whether someone is "pacing up and down" the highway suggests that Lyle was being watched for a considerable amount of time. He wasn't just pacing, but rather pacing "up and down". However, the motel is not on the main road according to Google Maps, so I wonder how BW knew this. Unless someone who was working at the grocery store told her (echoing point 3 about the store/motel being connected).
Balthazaro found photos taken by someone who passed through that area on a trip, some of which have pictures of the motel and the store. B may (or may not) have been mistaken about seeing him "pacing up and down" near the highway, because Balthazaro said that the motel is not there but behind the grocery store and trailer park.
And my own query about the grocery store - if he wasn't known to have been seen there, how did he get a drink?
