I am not sure if this is new of novel information. There are 2 instances in 6x01 of the suspects tracking screen. The first is when lisbon leaves the dinners to make a phone call to van pelt. This is when she confirms tracking is up and it flashes the first shot of the tracking. The second instance is when lisbon is sitting in her office alone at CBI.

I uploaded 1080p screen shots of each instance of the tracking screen below.

Each persons is represented by the first letter of their last name. The right side panel lists the addresses they are at.

Pay attention to Partridge in each frame. Partridge was already at "5570 West
Huron" when the tracking screen is first shown during the day. So Partridge was
present at this address for a some period of time.

He might have left his phone at this address when he learned of the surveilance so as to setup his real or fake death. Which ever you prefer to believe.

So anyone have any idea why he would already be present at this address?


Also as a side note. We all know TV Shows and Movies love to use the 555 prefix for fake telephone numbers. It is used in the tracking screens above. They are all fake numbers being tracked.

Why was Patrick Janes phone number a non-555? It is shown clearly on lisbons phone. here is a screen shot. The number is 310-795-9882.

I tried some "What's my phone spell?" services. It doesn't seem to spell anything though. This might be some oversight. I just found it curious. I don't have a theory about it really.
