Buyer9901,
Tragic!
I am so sorry to hear of this. Please, can you provide some details and perhaps photos so other forum members might keep an eye out for it?
Also, can you tell us if it was locked at the time and if so, by what means? I'm trying to get a better sense of what works to keep a bike secure in a given circumstance so if, say, a particular brand of lock proves vulnerable I can avoid it.
Again, I am surely sorry for your loss and really feel for you. I hope it will turn up soon...
Best,
Dan.
