Zeitgeist - Deus Ex Machina
A man with a pencil thin mustache who was killed 1 hour after Nelissa. He had a wound that smelled of engine grease, faint shadow magic.
Update: Turns out he isn’t dead, or at least someone is posing as Roger Porter. A man using that name and matching his description arrested Ava Figueroa, but neither of them have been seen since.
Update 2: Looks as though he really is dead and his likeness was being used by Cyllian Creed a.k.a The Shadow Man.
