Macbookpro was stolen/recovered - how to track accessed wireless networks?

Question

Hi All,
I have a MacBook Pro that was stolen and then recovered weeks later from someone who was not the original thief... Is there a way to find out the names of wireless networks accessed in hopes this would lead to the ID of the original thief? I've been looking at Console log under Diagnostic and Usage Messages, and here I can see exactly when the machine tries to autojoin wireless networks that have been remembered (and this is very useful), but wondering if I can find out the actual name of the network(s) joined in the hours after the laptop was stolen from me.
Thanks for any info you can provide!
For example - does this log below provide any revealing info?

Try the following to see if this will provide some information:
Open System Preferences (gear icon) on the dock
Open Network
Click on the AirPort connection on the left of the window
Click Advanced at the lower right
A list of previously joined networks will appear if the option to remember networks has been checked...unless this information has been deleted.
