WASHINGTON — In 2015, millions of people watched “Making a Murderer,” a Netflix documentary series about the murder prosecutions of two Wisconsin men. Opinions varied on the guilt of the program’s central figure, Steven Avery, who was convicted of killing Teresa Halbach, a 25-year-old photographer.
But many people were made powerfully uneasy by the treatment of Mr. Avery’s nephew, Brendan Dassey, whose videotaped interrogation was among the most gripping parts of the series.
Mr. Dassey, 16 at the time, was a study in pathos: hapless, lost, scared, painfully awkward, trusting, susceptible to suggestion and close to if not over the borderline of intellectual disability.
Two investigators feigning fatherly concern fed Mr. Dassey crucial details and elicited a halting, mumbled and contradictory confession. On the strength of that confession and almost nothing else, Mr. Dassey was convicted and sentenced to life in prison for raping and murdering Ms. Halbach.
On Thursday, the Supreme Court will consider whether to hear Mr. Dassey’s appeal.
The court has long said that “the greatest care must be taken” in making sure that confessions obtained from juveniles are voluntary. Mr. Dassey’s case could allow the justices to assess whether that command was taken seriously by courts in Wisconsin, which refused to suppress his confession.
It could also allow the justices to consider mounting evidence that false confessions from juveniles play a role in a disproportionate share of wrongful convictions. According to one study, 42 percent of exonerated juveniles had falsely confessed, compared to 8 percent of adults.
Mr. Dassey was interviewed for hours without a lawyer, a parent or any other adult who might have been alert to his interests. But the investigators who questioned him assured him that he had nothing to fear from them.
“Yeah, we’re cops, we’re investigators and stuff like that, but not right now,” said Tom Fassbender, a special agent with the Wisconsin Department of Justice. “I’m a father that has a kid your age, too. I want to be here for you. There’s nothing I’d like more than to come over and give you a hug.”
The investigators teased out contradictory statements from Mr. Dassey, steering him toward their theory of the case.
They knew, for instance, that Ms. Halbach had been shot in the head, though this fact had not yet been made public. What followed was like a game of 20 Questions.
“Something else was done,” said Mark Wiegert, an investigator with the Calumet County Sheriff’s Office. “Something with the head.”
Mr. Dassey’s first try: Mr. Avery had cut off Ms. Halbach’s hair.
His second try: Mr. Avery had punched her in the head.
His third try: Mr. Avery had told him to cut Ms. Halbach’s throat.
At this point, Mr. Dassey gave up. “That’s all I can remember,” he said.
But the investigators were not done. “All right,” Mr. Wiegert said. “I’m just going to come out and ask you. Who shot her in the head?”
Thus prompted, Mr. Dassey said that “he did,” referring to his uncle.
Asked why he had not mentioned that shocking assertion earlier, Mr. Dassey said, “Because I couldn’t think of it.”
By the end of the interrogation, Mr. Dassey had confessed to gruesome crimes. Then he asked if he could return to school in time for a sixth-period class. He had a project due.
When his mother asked him how he had been able to answer the investigators’ questions, he said he had guessed. “That’s what I do with my homework,” he added.
Mr. Dassey and his family were completely overmatched by the criminal justice system. In a call to his mother from jail, for instance, Mr. Dassey said he had been told that some of his statements had been “inconsistent.” He did not know what the word meant, so he asked his mother. She did not know, either.
A Wisconsin appeals court upheld Mr. Dassey’s conviction. But a federal judge and a divided three-judge panel of the United States Court of Appeals for the Seventh Circuit, in Chicago, ruled that Mr. Dassey’s confession should have been suppressed. Without the confession, Judge Ilana Rovner wrote for the majority, the case against Mr. Dassey basically evaporated, as “no one ever found a single hair, a drop of blood, a trace of DNA or a scintilla of physical evidence linking Dassey to this crime.”
The full Seventh Circuit reversed the trial judge’s decision by a 4-to-3 vote, saying that Mr. Dassey could not overcome barriers in a 1996 federal lawthat makes it hard for federal courts to grant relief to people convicted in state courts.
In dissent, Chief Judge Diane P. Wood wrote that this was a “travesty of justice.”
Mr. Dassey is represented by Seth P. Waxman, who served as United States solicitor general in the Clinton administration and later helped persuade the Supreme Court to abolish the death penalty for juvenile offenders.
“Put simply,” Mr. Waxman wrote in his petition seeking review in the new case, Dassey v. Dittmann, No. 17-1172, “the interrogators took advantage of Dassey’s youth and mental limitations to convince him they were on his side, ignored his manifest inability to correctly answer many of their questions about the crimes, fed him facts so he could say what they wanted to hear, and promised that he would be set free if he did so. The resulting confession was more theirs than his.”
The Supreme Court seldom agrees to hear cases merely to correct errors in a single case, even ones with grave consequences. But a supporting brief filed by scores of current and former prosecutors urged the justices to hear Mr. Dassey’s appeal in light of the attention “Making a Murderer” had drawn to his confession.
“It affected the way everyday Americans view our justice system,” the prosecutors wrote.
