AHA!....i think he was going around and looking at cars on the sheet that says NOTES, that would explain the reccurences and the circling, he was keeping the vehicles separated.....he went to go see a car and got murdered by the owner?? oh yeah i live in SOCAL, so the freeway thing was a longshot....i also believe that this man has Aspergers and Dyslexia....but they balled up his symptoms as Aspergers. One word keeps calling to me .... PSESHLE....take the first three letters PSE change them to SPE and add SHLE SPESHLE....this guy had the basics, mixed with his own different thinking style.
