Were DC Water involved in plot to kill Seth?

(Right click new tab for full image) Drop Shafts on 1st Street and Adams Street next to Flagler Place & W Street.

I created the info-graph from this Anacostia Tunnel System and this DC Water Clean Rivers using Google Maps

Here's some short videos on these tunnel projects: Drop Shaft at Adams Street & Flagler Place 1st Street Tunnel Project

Video and Article here explains full project: National Geographic

Theory: Did the FBI use the tunnel to interrogate Seth before they killed him?

It's a 100 feet under the street and has a train / trolley system that carries DC Water staff and tunnel workers for miles to the Blue Plains Water Treatment Plant.

Are DC Water involved? They operate the tunnels. Did they switch off the street lightsand refuse to install security cameras in the days surrounding his murder while they worked on the Anacostia Tunnel Project? The lights were out in either Flagler Place or Adams Street (or both?
