Case Remains is a true crime podcast about unsolved murders and missing persons, and each numbered episode follows a single case as far as the record goes. Before most cases are named, a brief hook sets the stakes. A husband takes a phone call and learns he has two hours to pay up to save his wife. A woman comes home from visiting relatives to find her family destroyed. Then the narration settles into a steady account that puts the evidence first. The Maria Bögerl episode is set in southwest Germany near the Bavarian border. It looks at who could have entered a house that showed no sign of forced entry, down to a spare key hidden in an artificial stone in the garage. It also sets two readings against each other: the police thought the kidnappers had watched the family and planned the crime carefully, while Frank Roselieb, a kidnapping expert from the Kiel Institute for Crisis Research, believed one person acted alone. Marilyn Bergeron's movements are traced through security footage and her credit card, including a $3 coffee bought 13 miles from where a camera had recorded her earlier that day. Her family's belief that someone gave her a lift is weighed against the distance and the busy main roads she would have had to walk. In the Kaitlyn Arquette case, the narration follows Detective Steve Gallegos's questioning of a man named Yoon, whose gun residue test came back negative. The 1987 killings of Phillip, Kelli and Sherri Fager in Wichita, Kansas bring in Lieutenant Ken Landwehr, who later played a key role in the capture of BTK. They also bring in a letter BTK himself sent to the Fager home. The public speculated that he was the killer, the police dismissed any connection, and the show reports both. Pearl Kongsle's 1959 death in Seattle involves an explosion, two young men seen running from the house in the month before, and lie detector tests passed by two men who knew her. Brooke Henson's case takes a crueler turn. Seven years after she vanished, her personal information was used to apply for a housekeeping job in New York, and her family were told she had been found. Those hopes did not last. The closings rest on what is still unknown: the single DNA match that could name Maria Bögerl's killer, the open question of who killed Kaitlyn Arquette and why, and the porch lights some people still leave on for Brooke every Fourth of July. The Fager episode's final stretch instead quotes a Kansas defense lawyer on juries and the presumption of innocence.
