Bike was locked on back porch along alley. Was present when leaving for work at 7AM. Missing when I arrived at my apartment around 5:15PM. Thief likely assumed everyone was away at work. Girlfriend's car was not in our parking spot which assured them no one was home. There was a handyman/worker working on neighbors house next door that had parked in our spot most of the day, says he remembered seeing bike on our porch when he arrived in the morning. I approached him, asked if he had seen anyone suspicious walking around during the day. I even asked to look in the back of his truck as if he may have been the person with the tools to break my lock. It of course was not there although it's obviously possible he could have driven away during the day to stash it and come back.
