Madison Allen has learned not to listen to true crime podcasts while riding the bus to her Uptown bartending job.
"I look around and I think everyone looks like a killer," said Allen, of Minneapolis.
Allen is particularly fond of "The Last Podcast on the Left," which she listens to "obsessively." The podcast has more than 300 episodes featuring three hosts who chat about serial killers, cold cases and tales of Satanism, the occult and conspiracy theories.
"Their research is awesome; they dig up details from multiple sources and look at all sides of a crime," Allen said. "It's fascinating to try to get inside the psyche of people who could do things like what they talk about."
Allen is part of a rapidly expanding audience eager to plug in their earbuds and download gripping audio stories about missing coeds, butchered lovers and human monsters who prey on the innocent and unsuspecting.
Murder, from the headline-grabbers to the obscure cases, has long been a television staple, with "48 Hours," "Dateline" and an entire cable channel, Investigation Discovery, devoted to telling and retelling morbid stories of shootings, stabbings, beatings and contract hits. Recent bingeworthy documentaries on Netflix and HBO have further fired up fans of coldblooded tales.
Now podcasting has become the latest evolution in the genre for those who want to hear a gory story while they drive, fold laundry or walk their dog.
"The long history of the genre goes back to True Detective magazine," said Laurie Ouellette, a professor of communication studies, cultural studies and comparative literature at the University of Minnesota. "Every version of a crime story uses the same markers — descriptive information, suspense, building in clues and cliffhangers, finding the story's heroes and villains and then packaging it as entertainment."
