Altitude Crime is a Colorado true crime podcast hosted by Amelia Allen, and the state line is its editorial filter. The closing credits name her as the person who wrote, recorded and edited each episode. The case list spans eras. She introduces 'The Kidnapping of Charles Boettcher II' by noting the show was overdue for a historic case, one she had first mentioned back in episodes one and two. The story involves kidnappers who released Charlie before collecting, a father who paid the ransom anyway with police in tow, and a money drop at a bridge north of Denver where officers watched the pickup, gave chase and lost the kidnappers. Other cases are far more recent. In the killing of Helene Pruszynski, a case reopened more than once without the eventual suspect ever surfacing, Douglas County deputies trail a man named Clanton in Lake Butler, north of Gainesville, until he leaves a beer mug behind, and a CBI test returns a match. Even the arrest has a twist: investigators approach him with a story about a securities fraud case and a stolen identity. 'Dating App Murders' takes up the death of Stacey, who worked for the nonprofit Partners Seeking a Cure. Her death was first listed as undetermined, and almost three years later her husband, Robert Feldman, was arrested and charged with first-degree murder. The forensic detail can be stark. Recounting Gannon's case, Allen describes a Blue Star search that found blood evidence throughout the family home, alongside three weeks of canine, horseback and drone searches and a neighborhood that turned its lights blue, his favorite color. Ted Bundy gets more than one installment. 'Ted Bundy in Colorado - PART TWO' recounts a Clear Creek County investigator, Bob Denning, questioning Bundy about a victim named Shelly; Bundy admitted the killing and then refused to say more. Allen reads that refusal as a small win for Shelly, and asides like that are where her own sympathies show. Before getting into 'Therapists or Murderers - The Case of Candace Newmaker' she briefly leaves Colorado to comment on the Gabby Petito case, stressing that the evidence would have to tell that story. Sourcing stays visible. She credits 9 News reporting by name, posts sources on the show's website, and keeps a Suggest a Crime link there for proposed cases. Follow-up coverage gets a full episode too: 'The Update Episode' exists because the short updates she usually sends out kept growing, so it recaps several earlier cases and gives the episode number for each. Plugs for a Patreon tier with a bonus full-length episode and ad-free episodes frame the stories, along with warm thanks to the listeners she calls the 'crime clan'. What a listener gets is Colorado cases worked through searches, lab results and arrests, from one narrator who keeps track of where each case goes next.
