so proderman was only recording official trips. doesn't leave us much to go on. no, it doesn't-- which is why i called charlie. he was nice enough to come down here on short notice. hey, charlie. how you doing? thanks for coming down. i was around here-- i was at that, uh, that detention center, with amita and the girl. is that that log book you called me about? yeah, it is, but like i told you, it's just the official runs. well, then you were probably able to get the total distance driven by the driver on each of his shifts. well, yeah, the company records daily mileages for each driver. how's that gonna help us, charlie? he still could have gone anywhere. no, his destinations are limited, by the total miles driven in each shift. okay, well, we still don't know where he went, and more importantly, where he could've taken those other girls. well, keep in mind that where he went couldn't have been random, you know, his choices were influenced by things: by the time of day, and his location. so you mean like if it was noon it's likely that he went to lunch. exactly
