The Sunset Murders

The Sunset Murders are an ongoing series of murders that occur in Devils Lake throughout the series.

Police Investigation
At some point in season 1, dead bodies began washing up on the shore of Creel Bay. The trend is first referred to as the Creel Bay Drownings. In season 2, however, Rosa Hernandez reaches the conclusion that there are actually two disconnected sets of bodies: one set has clean toxicology screenings and no causes of death other than drowning, whereas the other set have high concentrations of scopolamine in their systems and show signs of violent struggle. Following this revelation, the police look for other connections within the two sets of victims and determine that all scopolamine-intoxicated victims are residents of the Sunset Trailer Park.

Collaborating with DEA agent Rashad Jones, Rosa is able to determine that scopolamine is being shipped in to a Devils Lake P.O. Box from Yugoslavia. The police investigate the supposed owner of the P.O. Box and discover that she died twelve years prior and that the name is being used as a cover. During a stake out of the post office, Rosa sees a man with a scarf and sunglasses retrieve a package from the P.O. box and get into a car with fake license plates. She tails him in an unmarked police car, but the man notices that he is being followed and speeds up to try to evade her. During the high speed pursuit, the Weeping Dog runs out in front of Rosa's car and she swerves to avoid hitting it, driving off the road into a ditch. The man in the scarf escapes. Later, the car with fake plates is discovered abandoned in the Walmart parking lot.

Confession
The police are never able to identify the sunset killer, but near the end of season 4, Charles Kemp confesses to the murders to a comatose Terrence Parker. Charles claims that he was traumatized by being trapped in the Orange Light Road for several days and that his brain made an irrational connection between the Road and the Sunset Trailer Park. In this same confession, however, Charles's contempt for poor people is also made clear, implying that his hatred of the lower classes may have factored into his motivations.
