This is a black and white film that came out no earlier than 1999. It's a documentary or it's done in the style of a documentary, from a director who's still making movies. This might've been their first film or first fiction film. It's about murders in middle America, possibly in a single town (and the name of the town might be the name of the film.) I don't remember if the murders are connected. If I remember correctly, people never appear on camera. The imagery is all evocative while we get the details of the murders, like sheets on a laundry line or sun rising in the tall grass.
