OP, I am so sorry that you were subject to trolls and harassment for trying to do the right thing. Don't even engage the trolls, they are not worth your response. I do suggest though that you provide as much as this information as you can to the Maine State Police. Please google their contact information and act on it. They will not ignore you. You may save a life. I would take this very seriously. The downside of not doing so could be tragic.
