I had mentioned over on TalkBass....That yes he was inbetween residences at the time....Considering we are looking at close to 70k worth of basses, im betting (hope) you would rent a climate controlled storage for these fine instruments.....IF that was me, i would have also set up a bed, have a loaded shotgun right beside me and a electrified boobie-traped door incase someone tried to break in. Also you think you would just take them to a family or friends place to keep safe. Fishy fishy indeed.
Almost guaranteed this was an inside job, and not some “random” break in and stumbled on a whack of basses, with him only scheduled to be there a short time.
