Talking Points

Recent interactions between the hosts and their guests.

The Woman Who Rode With the Wild Bunch | Chris Enss on Laura Bullion
Q: Why do you think Laura Bullion is often overlooked in histories of the Wild Bunch, and what does her story add to the broader narrative of the Old West?
Her story highlights the significant, yet underappreciated, role of women in frontier crime and survival; Laura's loyalties, clever forgeries, and ability to navigate both high society and outlaw life show a more complex social fabric of the West, challenging the male-centric myths that dominate popular histories.
The Woman Who Rode With the Wild Bunch | Chris Enss on Laura Bullion
Q: Could you walk us through how Laura Bullion connected with the Wild Bunch and what drew her in?
Laura grew up in a rough Texas environment surrounded by disenfranchised cowboys after the Great Die Up, which led her to cross paths with Will Carver and later Ben Kilpatrick. Her resemblance to her aunt and Carver's interest in her, plus the gang's extensive network, drew her into a life in their orbit, including work at Fannie Porter's brothel that kept her close to the action and the men she cared about.
Why Medical Examiners Can’t Rush to Conclusions | Nolan Wells Case with Dr. Priya Banerjee
Q: Do you ever release preliminary results?
No. Preliminary results are not released because autopsy data needs to be definitive and data-driven; multiple factors including investigation, autopsy, and toxicology must align before conclusions are drawn.
Law Enforcement in the Wilds | Ed Newcomer & Tony Latham
Q: What's the title of your book that details the Art Teed story?
The book is titled A Case So Cold, The Murder of an Idaho Game Warden, documenting the long-unsolved murder and eventual cold-case resolution that brought renewed attention to Art Teed and the surrounding events.
Law Enforcement in the Wilds | Ed Newcomer & Tony Latham
Q: So Tony, can you just talk a little bit about Deputy Warden Teagues and what that case was and what it resulted in recently?
The Teed case began with a missing officer in 1934 and unfolded into a decades-long investigation that was rekindled by a single informant's tip, leading to the identification of the shooter and closure that finally recognized the officer down, though prosecution did not occur for everyone involved due to ages and circumstances at the time.
