One Minute and Forty-Three Seconds calls itself 'a true Unsolved Mysteries podcast', and its subjects are people who vanished and bodies that were never named. The cases in its titles include Bryce Laspisa, Nelda Hardwick, Joan Risch, the infant Sabrina Aisenberg, and Diamond Bynum and King Walker. Most of the material here is conversation. The host has done the research and reads it out in order, while a guest listens, reacts and asks questions. Before one case, the host admits there are a lot of details to get right. The guests include Erin, introduced as Megan's sister, and Elaine, who is thanked on air for being a faithful returning guest with good insights. The small talk before each case is warm, and the tone turns serious once the file comes out. A lot of the discussion is comparison. In the Nelda Hardwick conversation, host and guest compare a Jane Doe killed on a highway with two missing women by reconstruction images, age and height, then consider a coroner's opinion that the match was all but certain. The Sabrina Aisenberg episode puts age-progressed photos of the missing baby next to pictures of an abandoned child known as Paloma Unknown. The host points out a similar expression around the mouth and promises to post the images to Instagram for people who can only hear the descriptions. In Unclaimed: Stories of the Unidentified, a larger group goes through the description of a woman called Becca, including her height, hair, clothing and purse, and notes that investigators have already ruled out a list of missing people. The Bryce Laspisa case is told as a timeline. A 19-year-old tells his worried parents he will pull over to sleep, and hours later a police officer comes to the family's door asking about an abandoned beige Toyota Highlander. The Joan Risch episode carries a spoken content advisory, and the conversation with Erin keeps coming back to the blood at the scene and the question of who tried to wipe it up. Not every episode is a chat. The Diamond Bynum and King Walker episode is a scripted narration that starts with Gary, Indiana, a steel company town that lost more than half its population, before turning to details such as an untouched chocolate cake in the fridge. It ends with a Gary Police Department tip line and a reminder that someone out there knows something. Theories are raised and then held loosely, and one conversation ends by inviting anyone who disagrees to say so. The endings stay focused on the families: a hope that a missing young man is happy if he is still alive, a nod to relatives' right to privacy, and a wish that the episode reaches the right person. Every episode here signs off the same way, with a dedication thanking Dad as its 'number one fan' and a line saying Skipper the Cat has given approval.
