Guys, I went back to season 6 episode 1 to look for clues in the last scenes.  A few things stood out which have already been discussed on this site, so I thought I would post a new one for us to sink our obsessive minds into.

At 36.58 minutes, Lisbon is looking at the GPS Mobile Tracker/Locator.  It shows the location of the 7 suspects 'phones' as follows:-

K (Kirkland) - Los Angeles
S1 (Stiles?) - San Francisco
B (Bertram) - Sacramento
P (Partridge) - Sacramento
S2 (Smith?) - In Transit
H ( Haffner) - In Transit
M (McCalister - In Transit

According to the Tracker, Bertram is the closest to Partridge.  But heres the number one thing I find interesting....In recent episodes we are told that since Lorelei's death, Brett Stiles was out the country.  Both S1 and S2 above clearly show us otherwise.  Therefore, it was either a lie he was out the country, he left his phone in the country or theres a link to Brett Partridge's apparent murder and him being in the country..
