stolen Kona LANA'I

I leave my bike behind our building in a fenced-in yard, out of sight from the street. Only access to the area is by squeezing between head-high bushes in the front between the buildings. This area has had higher traffic due to construction in the last week. My partner goes out and sits next to it daily, but in recent days only done so when it was dark. I saw at 6pm on August 27 that it was gone. I walked around the entire property to check (in case the construction workers moved it to do their work) and walked part of the bike trail next to us in case it was dumped, no sign of it anywhere. Last time I know for sure it was back there leaning against our apartment was August 20th at 12:37pm. It was unlocked, other items that were next to it are still untouched. I have reported it to property management. We have experienced several security issues on the property (Liberty Management Group, Timber Grove Apartments) in the past 2 weeks, including vandalism on August 24/25, theft of packages from other apartments, and 2 cars broken into (attempted to steal, didn't succeed). This may have occurred the night of the vandalism.
