Jeff (full name Jeffery) was a father in the Gracepoint community who knew Ellie Miller. While at the park, he confronted Ellie about the murder investigation, asking if the kids were safe or whether they should be kept inside. His wife, Nikki, tried to make him leave Ellie alone. Ellie reponded by saying that the kids should be fine as long as he watched them, and that she would really like to spend some time alone with her own kids. (Episode 2)
