During the quest Spreading The News, the quest marker for him may indicate he is deep underground outside of New Atlantis. Reloading the area may fix this by teleporting him to the area above the ground he seems to be stuck in, this location may be deep in the wilderness outside the city.

If reloading the area doesn't work, go to commercial district, then go GalBank, you can see a door over the buildings. See the image one. Once inside, you will fall, take care.
You can walk over the rocks inside the buildings, do not jump, just walk to the marker (image two),
And let's fall again, take care again to not die (image three).
Once you get to the ground, the most difficult part is to jump over the structures (image four).
