Brendan Dassey

Photographer Teresa Halbach, born March 22, 1980, in Kaukauna, Wisconsin, was reported missing by her parents on November 3, 2005.

Halbach, who had not been seen since October 31, resided next door to her parents in Calumet County.

Brendan Ray Dassey (born October 19, 1989) is an American convicted murderer from Manitowoc County, Wisconsin, who at 16 confessed to being a party to first-degree murder, mutilation of a corpse, and second-degree sexual assault.

He was sentenced to life in prison with the earliest possibility of parole in 2048.

His videotaped interrogation and confession, which he recanted at trial, substantially contributed to his conviction.

The series examined the 2005–2007 investigation, prosecution, and trials of Dassey and his uncle, Steven Avery, both of whom were convicted of murdering the photographer Teresa Halbach on October 31, 2005.

After his conviction, Dassey's case was taken by the Center on Wrongful Convictions of Youth.

Halbach was known to have visited the Avery Salvage Yard in Manitowoc County on October 31, 2005.

On November 10, 2005, following the discovery of her Toyota RAV4 vehicle partially concealed on the Avery property, Calumet County Sheriff Jerry Pagel conducted a search and found the charred remains of Halbach.

Her cell phone, license plates and car key were also recovered.

On November 15, after Steven Avery's blood was found in her vehicle, Avery was charged with the kidnapping and murder of Halbach, mutilation of a corpse, and illegal possession of a firearm.

During the investigation, Dassey, Avery's alibi, underwent a series of interrogations without counsel or parent present, although Dassey and his mother consented to the interrogations, in which investigators made false promises to Dassey using approved interrogation techniques.

While being interrogated, Dassey confessed in detail to being a co-conspirator in the rape and murder of Halbach and the mutilation of her corpse.

His confession was later described as "clearly involuntary in a constitutional sense" by a US magistrate judge whose opinion was overturned by an appellate court.

The U.S. Supreme Court upheld the appellate court by refusing to hear the case.

He was arrested and charged on March 1, 2006, with being party to a first-degree homicide, sexual assault, and mutilation of a corpse.

The special prosecutor Ken Kratz held a major press conference about the two cases, discussing the charges against Avery and Dassey, and reading verbatim elements of Dassey's confession.

It was widely covered by TV and newspapers.

Dassey later recanted his confession in a letter to the trial judge.

He said he got most of his ideas from a book.

Dassey was interrogated on four occasions over a 48-hour period, including three times in a 24-hour time frame with no legal representative, parent, or other adult present.

Initially interviewed on November 6 at the family cabin in Crivitz, Dassey was interrogated via the Reid technique, which was developed to permit and encourage law enforcement officers to use tactics that pressure suspects to confess.

Dassey had been clinically evaluated as being highly suggestible, which makes a suspect more compliant and can ultimately lead to improper interrogation outcomes such as false confessions.

Dassey recanted his confession and informed his defense counsel.

He later charged that his first defense counsel collaborated with the prosecution to get Dassey to plead guilty in order to testify against Avery.

The defense counsel was replaced.

Dassey's first appointed lawyer, Len Kachinsky, was removed by the court on August 26, 2006, due to his decision not to appear with Brendan during the May 13 interrogation.

He was replaced by two public defenders.

The Dassey trial began on April 16, 2007, with a jury from Dane County, Wisconsin.

Parts were shown, but much was left out, in the Netflix documentary series Making a Murderer (2015).

The Netflix series Making a Murderer (2015), which chronicles the trials of Dassey and Avery, has generated global dialogue centered around wrongful convictions, coerced confessions, interrogation of minors, and criminal justice reform.

In August 2016, a federal magistrate judge ruled that Dassey's confession had been coerced and overturned his conviction and ordered him released, which was delayed during appeal.

In June 2017, a divided panel of the United States Court of Appeals for the Seventh Circuit affirmed the magistrate judge's order overturning Dassey's conviction.

In December 2017, the full en banc Seventh Circuit upheld Dassey's conviction by a vote of 4–3, with the majority finding that the police had properly obtained Dassey's confession.

Brendan Ray Dassey was born to Barbara and Peter Dassey in Manitowoc County, Wisconsin.

He has three brothers (Bryan, Bobby, and Blaine) and a half-brother (Brad).

At the time of his indictment, Dassey was a 16-year-old sophomore at Mishicot High School.

With an IQ in the borderline deficiency range, he was enrolled in special education classes.

Dassey was described as a quiet, introverted young man with an interest in WWE (he was reportedly upset when he missed WrestleMania 22 ), animals, and video games.

Before this case, he had no involvement with the criminal justice system.
