Shared. This is a bummer, I hate when stuff like this happens. My jeep got broken into late last week, a pair of sunglasses was taken but they were $1 Rayband knock offs.
A few years back my car was broken into and it was a mess, they took a lot of my stuff, ipod, maglite (really bummed about this the most), sun glasses, aftermarket radio, and some other bits and pieces. I learnt from that not to leave anything inside, in sight or hidden, just take it into the house each night.
