I think it is worth taking a look at a map of where the recent missing DC girls were taken vs. location of the tunnels that @quantokitty laid out evidence in this thread a couple of months ago - https://voat.co/v/pizzagate/1551878

It appears to me that about five of the missing girls are along the lines of the tunnels she found. I am not sure what the girls on the other side of the river might be close to in our investigation but maybe some of you who have a better understanding of the DC area could make some connections?
