    This is just the tip of the iceberg of what the people of Gander did for us. You can’t truly understand these people unless you visit there. They are friends for life and they never want anything in return. It’s just the way they are!!!

Talking Points

Recent interactions between the hosts and their guests.

When the Planes Came to Gander: A Flight Attendant’s 9/11 Story | Sharlene Bowen
Q: When did you know something was different on the flight?
We sensed something was wrong as soon as the captain spoke of needing to land and then confirmed a serious incident in New York, quickly realizing we were diverting due to the unfolding crisis.
Jabez Spann: Nine Years Later, His Parents are Still Fighting for the Families of Missing People
Q: Tell everybody how they can get in contact with you or how they can support the foundation.
Contacts and online presence are shared: jabezspannfoundation.com, ifwe couldspeak.com, and the Missing Our Voices podcast on major platforms like Apple and Amazon; the hosts emphasize reaching out through these channels to support families and access resources.
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.
