Bicycle detail

The bike was stolen from inside my home at 3340 Bell St. at an unknown date. The bike was stored in a shared storage space that no one has access to except the upstairs tenants and us (downstairs tenants). The space is a closed off, secure place at the back of the house, and therefore I do not check every day to make sure my bike is still there. I did not feel the need to lock it up as it was stored inside my home. I believe my upstairs neighbor stole the bike and has it or has sold it. This hypothesis was formed after a number of other items went missing from our home such as my roommates rings, a very large coin jar, and a check from my checkbook. Additionally, seeing as she is the only other person who has access to this area, I have reason to suspect that my bike could have been stolen by my upstairs neighbor.
