Imagine the worst day of your life, when you did the one thing you are most ashamed of. Now imagine having to convince a panel of strangers — who suspect you might be lying — how sorry you are. After years of preparing for this moment, you get only minutes to make your case. And the stakes couldn’t be higher: The rest of your life depends on whether or not the strangers believe you.

This is how people seeking parole often describe the experience. Daniel Medwed, a law professor at Northeastern University, describes parole hearings as “a trap for the unwary,” where those who are mentally unprepared for the emotional complexities of the process can find themselves at a grave disadvantage.

Every year in the United States, tens of thousands of people appear before parole boards asking to be released from prison. These boards play an outsized role in the criminal justice system — how much time someone actually spends in prison, or in some cases, whether they get out at all, is often decided not by a judge or jury, but by a parole board. And yet, few people understand how they work.

Part 3 of Violation examines parole boards, largely secretive institutions that operate in many states with few rules and little oversight. These panels are supposed to be independent, but often do their work under pressure from the politicians who appoint them. In the best of circumstances, parole board members are assigned a virtually impossible task: to predict what human beings they barely know are going to do in the future. And they have people’s lives and the public’s safety in their hands.

What happens at parole boards is a huge part of Jacob Wideman’s story, and his story tells us a lot about the parole system in America. After serving 25 years behind bars for killing his summer camp roommate, Eric Kane, Wideman went before a parole board in Arizona for the first time. Starting with his first hearing in 2011, he was denied parole over and over.

Except for one time.

Not long after Jacob Wideman murdered his summer camp roommate, Eric Kane, in 1986 — seemingly with no motive — a question emerged in the breathless news coverage of the tragedy: Was Jake a “bad seed”?

It was no accident that some reporters latched onto the phrase. After all, it was plucked straight from perhaps the most famous book written by Jake’s own father, acclaimed author John Edgar Wideman, about his family’s experience with violence, trauma and incarceration.

But John Wideman wasn’t writing about his son Jake when he used the phrase “bad seed” in his seminal memoir, “Brothers and Keepers.” The book was published in 1984, two years before Jake murdered Eric. Instead, John was writing about his own younger brother Robby, Jake’s uncle, who years earlier had participated in a robbery that went very wrong. A man died, and although Robby didn’t pull the trigger, he was sentenced to life in prison.

“The bad seed. The good seed. Mommy’s been saying for as long as I can remember: ‘That Robby, he wakes up in the morning looking for the party,’” John Edgar Wideman writes in “Brothers and Keepers” — and reads aloud in this latest episode of “Violation,” a podcast series from The Marshall Project and WBUR. This idea from John’s book, of going “bad,” would be applied to Jake, too, although John was disdainful of the concept.

“Bad Seed,” Part Two of “Violation,” tells the story of Jake’s Uncle Robby through interviews with John as well as with Jake, who remembers having epiphanies as a boy that he would somehow follow his uncle’s path. The episode also brings listeners through the harrowing weeks and months after the murder of Eric Kane, when Jake Wideman turned himself into authorities and began his long journey through the criminal justice system.

Ultimately, this episode asks: What should happen to kids like Jake?

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.

In 1986, while on a summer camp trip to the Grand Canyon, 16-year-old Jacob Wideman fatally stabbed his roommate, Eric Kane. Jacob confessed to the murder, but couldn’t explain why he did it.

The crime devastated both boys’ families. For the Widemans, it was also a haunting echo from their family history.

Just two years earlier, Jacob’s father, acclaimed author John Edgar Wideman, had published "Brothers and Keepers," a memoir that grappled with how his brother, Jacob’s uncle Robby Wideman, was sentenced to life in prison for his role in a fatal robbery. How could another inexplicable crime happen twice in two generations?

Jacob served decades behind bars for killing Eric Kane. Then in 2016, an Arizona parole board granted him house arrest. Jacob’s release outraged his victim’s family.

It wasn’t long before Jacob was back before the board, fighting again for his freedom.

Violation, a new podcast from The Marshall Project and WBUR, tells the story of how this horrible crime has connected two families for decades. It explores suffering and retribution, as well as power and privilege. It also pulls back the curtain on parole boards — powerful, secretive, largely political bodies that control the fates of thousands of people every year.

Hosted and reported by The Marshall Project’s Beth Schwartzapfel, Violation debuts on March 22, with new episodes every Wednesday.
