We are constantly running in circles anyway aren't we? I wonder what the copper found that made him suspect gaskill? It's possible he is privy to some information we don't have, he made it sound like the guy was really really weird. I do believe AC and Gilgo are the same killer(s). Gaskill does;t appear to have a NY address so that is significant. Maybe someone can look in to his relatives, if he has a parent living on Long Island, then I would consider him as a POI as of know we really have nothing. Does anyone have a link to the story about the Prostitute who claimed to spend time with the killer and two of the victims and she tells the story of seeing one of the victims dead on the bed of a motel room? In this version of events, there is more than killer, so it's always possible Gaskill was part of the group.
Another thing, Barbara Breidor's daughter claimed she'd seen the sketch of the river man when he was at the door selling something. That narrows down possibilities in a large way and it means either the man was selling hoovers...or drugs. Highly unlikely he was a door to door vacuum salesman, so I think there is a good chance the killer could be a drug dealer. It explains so many things, why Megan left her phone, why amber went out in a sweatshirt (although Schaller makes it sound like she left for a date but sometimes I wonder if he didn't sell her out for a brick), why sugar bear left her coat to meet her special friend (i.e. drug dealer), Shannan and JB's short drive. A LOT of things point to the killer being a drug dealer.
