On a sunny day in March 2020, researchers in South Africa discovered the bodies of two giraffes. From what they could tell, the giraffes had died a few days earlier. But the cause was a mystery. To understand what happened, producer Dean Russell turned to the subreddit AskScience. He discusses his findings with Endless Thread co-hosts Amory Sivertson and Ben Brock Johnson. Credits: This episode was written and produced by Dean Russell. Mixing and sound design by Matt Reed. Amory Sivertson and Ben Brock Johnson are the co-hosts.

Why did Jacob Wideman murder Eric Kane? In 1986, the two 16-year-olds were rooming together on a summer camp trip to the Grand Canyon when Jacob fatally — and inexplicably — stabbed Eric. That night, Jacob went on the run, absconding with the camp’s rented Oldsmobile and thousands of dollars in traveler’s checks. Before long, he turned himself in and eventually confessed to the killing — although he couldn’t explain what drove him to do it. It would take years of therapy and medical treatment behind bars before Jacob could begin to understand what was going through his mind that night. It would take even longer to try to explain it to his family, to his victim’s family and to parole board members, who would decide whether he deserved to be free ever again. This debut episode of “Violation,” a podcast from WBUR and The Marshall Project, introduces the story of the crime that has bound two families together for decades. Jacob’s father, John Edgar Wideman, is an acclaimed author of many books on race, violence and criminal justice. He spoke with Violation host Beth Schwartzapfel in a rare, in-depth interview about his son’s case that listeners will hear throughout the series, including this premiere.

Evan Kail is a wise-cracking antique dealer and TikToker. Last September, his world turned upside down when one of his videos ignited an international media frenzy. In his words, the TikTok created a "perfect storm." The subject of the video? A photo album from WWII which Evan believed contained photographs of the Nanjing Massacre — a horrific episode during Japan's invasion of China in 1937. This episode is about historical memory, why the Nanjing Massacre is still an incredibly sensitive topic in China and Japan, social media virality, and the true contents of that WWII photo album. Credits: This episode was written and produced by Megan Cattel. Mixing and sound design by Emily Jankowski. Amory Sivertson and Ben Brock Johnson are the co-hosts.
