Fessel, thinking about that video you posted.
At 2:45 p.m., Somer is last seen by her siblings at Solomon and Gano (MPR).
Maybe she hides behind the tanks (she is seen by J., boy on his bike) until her siblings go by?
Maybe she goes to visit the workers at 1080?
Maybe OPAA -- on the swings?
(Ten minutes at each of the three places, tanks, 1080 and swings would eat up that half hour).
At 3:15 p.m., Somer is seen in the yard of 1152 with her face in her hands (on video posted above).
At ~4 p.m., Diena leaves the OP office and goes home. Somer is not there; she retraces Somer's route home.
At ~5:06 Diena flags down A. Coan and they head back to Horton.

I don't know where I'm going with that ... just trying to figure out who else might have seen Somer. I wonder if anyone saw JH that day out washing his car or smoking cigarettes while the children of GPE walked by.
