Kurt Sonnenfeld: Nancy’s Death, 9/11 Claims, and Extradition

Kurt Sonnenfeld is a former FEMA videographer charged with first-degree murder in the January 1, 2002 shooting death of his wife, Nancy, in Denver, Colorado. He fled to Argentina in 2003, rebranded himself as a 9/11 conspiracy theorist who claimed the U.S. government wanted him silenced, and has never returned to face trial. Argentina’s Supreme Court cleared his extradition in 2014, but a 2015 executive order from then-President Cristina Fernández de Kirchner overrode that decision. He remains in Buenos Aires.

The Death of Nancy Sonnenfeld

At 1:40 a.m. on New Year’s Day 2002, Sonnenfeld called 911 from the couple’s home on Clayton Street and told a dispatcher his wife had shot herself.¹ Officers found Nancy, 36, on a chaise lounge in an upstairs bedroom with a gunshot wound behind her right ear. A .45-caliber semi-automatic handgun lay on the floor. She was pronounced dead at Denver Health Medical Center at 7:30 a.m.²

Denver police found the scene inconsistent with suicide. The bullet entered the back of Nancy’s head rather than the temple or chin. The muzzle had not been against her skin when the shot was fired. The body appeared to have been moved from the edge of the lounge to the center. And investigators observed high-velocity blood spatter on Kurt Sonnenfeld’s face, suggesting he had been within a few feet of his wife when the gun went off.¹

Other evidence cut the other way. Gunshot residue was on Nancy’s hand, not Kurt’s. Only Nancy’s fingerprints appeared on the gun. Defense attorneys later pointed to a note torn from Nancy’s diary containing a Walt Whitman line, “What indeed is finally beautiful except death and love,” followed by the handwritten words “Kurt please get help.” Her attorneys called it a suicide note. Her mother, Eleanor Campbell, disputed that reading, saying Nancy had copied the phrase from a book, held a high-paying management job, and had come through an earlier divorce without difficulty.²¹

Denver police called the evidence “overwhelming” that Sonnenfeld had killed Nancy and staged the scene.¹ The Colorado Bureau of Investigation lists the case as an unsolved homicide.³

Charges Dropped, Then Refiled

Denver prosecutors charged Sonnenfeld with first-degree murder within a week of Nancy’s death. District Attorney Bill Ritter oversaw the case; Deputy DA Michelle Amico handled the prosecution.² Sonnenfeld spent more than five months in jail awaiting trial.

His defense attorney, Carrie Thompson, attacked the prosecution’s central forensic claim by arguing that Nancy had coughed or sneezed blood onto Sonnenfeld’s face after the gunshot, not that the blood was high-velocity spatter. Former Denver homicide Lieutenant Jon Priest later called that theory physically impossible, saying Nancy had no blood in her lungs.⁴

In June 2002, one day before a scheduled court date, the DA’s office dropped the charges. “We just ran out of time,” Ritter said, explaining that he doubted his team could secure a unanimous guilty verdict by the trial date. The dismissal was without prejudice, meaning prosecutors could refile. They never abandoned the theory of the case. Amico, who later became a district judge, wrote in a 2006 letter: “At no time did I ever convey that I believed Mr. Sonnenfeld was innocent. The People have always believed that Sonnenfeld was guilty of murdering his wife.”²

Investigators kept working. DNA from fingernail scrapings taken from Nancy’s body matched Kurt Sonnenfeld’s, a finding consistent with a struggle before the shooting.² Two jailhouse informants, Robert Dreyer and Damien Zane Whitehead, independently told police Sonnenfeld had confessed while in custody. According to Denver Post reporter Kirk Mitchell’s book The Spin Doctor, Sonnenfeld told the informants he had sneaked up on Nancy while she was passed out, placed his gun in her hand, and fired, wrapping his own hand in a plastic bag to avoid gunshot residue.⁵

A judge signed a new arrest warrant in December 2003. Sonnenfeld was already gone. He had left the United States for Buenos Aires on February 18, 2003, telling people it was a two-week trip.²⁶

The 9/11 Persona

Before all of this, Sonnenfeld had studied English and philosophy at the University of Colorado in Boulder and worked as a reservist videographer for FEMA. After the September 11 attacks, he was deployed to Ground Zero with access inside the fenced perimeter. FEMA personnel records show he did not arrive on site until roughly a week after the attacks, contradicting his later claims of immediate deployment.²

In Argentina, he built a new public identity around those weeks at the site. He claimed to have kept FEMA footage he never turned over, and said it contained evidence that the U.S. government had prior knowledge of the attacks. His most specific allegation involved a large, empty vault beneath World Trade Center 6 that he said appeared to have been cleared in advance. He also questioned the collapse of WTC 7. He framed the Denver murder case as retaliation, saying the government wanted to silence him because he “knew too much.”²⁵

Bill Ritter rejected the link outright. Asked whether the refiled charges had anything to do with 9/11, the former DA said: “Yeah, that’s not true at all. And it’s never been true.” Former FEMA colleagues also dismissed his claims, calling the conspiracy theories “unbelievable” and “embarrassing.”²

Sonnenfeld promoted his version of events in a Spanish-language memoir, El Perseguido (“The Persecuted”), presented at the 2009 Buenos Aires International Book Fair with the wreckage of the Twin Towers on its cover.² The New York Post reported that the book contained fabrications, including a false claim that Al Gore had given him an award for “technical innovation.”⁵

The Extradition Fight

Interpol agents arrested Sonnenfeld in Argentina on August 30, 2004, on U.S. extradition papers.² He spent seven months in Buenos Aires’s Devoto Prison.⁷ In March 2005, an Argentine federal judge released him and denied the extradition request, citing the possibility of a death sentence in Colorado.

U.S. officials later gave assurances that they would not seek the death penalty. On December 11, 2014, Argentina’s Supreme Court ruled that Sonnenfeld could be extradited, on the condition that any life sentence carry the possibility of parole, since a sentence without parole would violate the Argentine Constitution.⁸⁹

The ruling was never executed. On September 16, 2015, President Cristina Fernández de Kirchner’s government issued an executive order overriding the Supreme Court. Signed by five officials including Foreign Relations Minister Héctor Timerman, the order cited human rights grounds and the international principle against returning asylum seekers to countries where they could face persecution. The Denver District Attorney’s office said at the time it had not received formal notice of the decision.¹⁰

Where the Case Stands

Sonnenfeld remains in Argentina. He married an Argentine attorney, Paula, 40 days after they met in a Buenos Aires café, and they have twin daughters.⁷ The couple became directors of a home for children with HIV and AIDS founded by Nobel Peace Prize laureate Adolfo Pérez Esquivel.⁶ He applied for political asylum, though the available record does not confirm formal approval.⁸ No public reporting indicates that the 2015 executive order blocking his extradition has been reversed by any subsequent Argentine president.

Nancy’s mother, Eleanor Campbell, is still waiting. Commenting on her former son-in-law’s conspiracy persona and life in Buenos Aires, she said: “I think he went and found people who agreed with him in his hate of America. I don’t think they’ll send him back.”¹
