It's a shame that you've lost a brand new Jepp bag. How long was it "sitting" there? Don't give up hope though, I lost a brand new 3 cell Mag Lite a long time ago, and it stayed missing for just under a year, when lo and behold, it showed up in my cubby (we didn't have lockers back then, the new guys just had open cubbys.) Guess the guy who "borrowed it" was tired of seeing my name and employee number etched in the aluminum.
And it's a double shame that your first two posts on this web site have to be about someone stealing your stuff. As Famous Francis said "Any of you homo's touch my stuff, I'll kill ya."

Good luck with the retrieval process.
