Rumor, locally I heard people got caught going to strangers apartment building and trying to build a secret room to kidnap people under city road.
Could be near construction site.
Guy said he found in a regular heat building a secret propane hose and outside ground loose power cable in his building while doing renovations.
No propane service was offered at the building.
He said, homeless people were loitering watching the area around the rumored secret room, could be near construction sites at apartment buildings.
