IMO this guy moved on to his new life and new family. Sad to say, but I don't think he was too involved in Lindsey's life. That's the impression I'm getting.
As ugly a scenario as that sounds, clearly it's a possibility. And, if so, following an argument and dispute on Maple that evening between hopeful plans with Michaela for a sleep over, and troubles with brother J and the bike dispute, would it be too incredible to consider that Lindsey may have decided to "catch a ride" to
dad's place by an acquaintance who happened to drive by and who offered an understanding ear to her about all that she was experiencing: the divorce, the trouble, the brother, the screwed up plans that night since things weren't really going too well for her at all that night.
An impulsive acceptance of a "ride" from someone who lended a seeming understanding ear to her as she raged her way home, alone, and bugged by a whole lot of things at that moment in time, would be relatively quick, silent, and non-confrontational on Maple at that time.
Then, at the same general time, we hear about all of these spottings in and around the Fort Lewis area where the psychotic "Smiley" set out mattresses, toys, cell phone cameras, and other in order to lure children to his little woodland lair, and one or more individuals seeming to leading a LB lookalike along the highway just north of Fort Lewis.
Perhaps SB had set into his new life but it appears clear to me that Lindsey had not, and was
missing her dad at that point in time, the divorce being fresh on her mind and all of what was happening that night just got her worked up to the point where she became less than wise about decisions. This Friday evening was not going her way. Who knows, maybe the "white car" rumor mill thing was a reality and that white car just happened by Maple at that time because the driver was watching her swim with friends and was waiting for a time to take action. Perhaps she was just so annoyed with everything that she finally succumbed to the approaches of the white car driver in order to get back to dad.
Anyway, perhaps a consideration, at least a passing glance, imo.
