The bike was temporarily being stored on the garage ceiling, with the lock only on the bike itself, as we've recently moved in to a 3 unit flat. The garage door may have been accidentally left open (we're not sure, we hadn't left the condo). The last entry to the garage was around 2:30. Between 3:30-4:30, judging on the state of the treads and how fresh they looked, someone walked in and rode off on the bike. Around 4:45/5 o'clock, I went to go check on something in the garage, and noticed the main door was open, and the bike was gone. There were bike treads in the snow starting from the front inside of the garage (you could see the slip when the bike hit the snow). These led down the alley (parallel to Racine) heading north. I tracked the tire treads continuously in the snow out down the alley heading for a block or two then heading west, though they were more intermittent then, down Oakdale heading west, after hitting Lakewood, they seemed to turn left but I lost them after that. I did see an open garage, with active loading/unloading happening and a bike that I swore was ours, but it turns out it was new movers and the police questioned them and said it was their bike. It snowed a lot today and it is a small women's road bike with no winter tires - no one would be riding this bike as a commuter at this point in the year! Someone much taller than the bike's size must have reached it from the ceiling. Its kryptonite u-lock is still around the front frame/spokes of the bike. I filed a police report - but handed it to the officer who helped me out when he arrived (I wrote the description of the event, and was flustered, all on the same page...); I'll update this with the serial number and report number when I find them - hopefully ASAP, all of our receipts and everything are packed up so we are trying to find the serial numbers though for reference.
