Kurt Sonnenfeld maintains his wife Nancy put a gun to her head and killed herself in the early morning hours of Jan. 1, 2002. Denver Police think otherwise. However, investigators may never get a chance at proving their case. That’s because Sonnenfeld has a new life, a new wife, and is living in Argentina a country that has yet to agree to extradite him to the U.S.

And if that wasn’t unusual enough, Sonnenfeld has told journalists in Argentina that he’s wanted in the U.S. because of something he saw while working at Ground Zero as a cameraman for FEMA.

“He’s using that terrible situation [9/11] to shield him from a murder charge,” says Leslie Lindberg, Nancy’s cousin.

Erin Moriarty and 48 HOURS investigate the death of Nancy Sonnenfeld and the outrageous claims Sonnenfeld has made that the U.S. wants to silence him in “The Strange Case of Kurt Sonnenfeld,” to be broadcast Saturday, Nov. 21 (10:00 PM, ET/PT) on the CBS Television Network.

“He is innocent,” Sonnenfeld’s new wife, Paula, tells Moriarty in her first interview on American television. “There’s nothing else to say.”

Sonnenfeld told police his wife committed suicide after a night out to celebrate New Year’s Eve. Police responding to the 911 call said the evidence didn’t really match up to what Sonnenfeld said happened.

“We were questioning nearly from the start that this had anything to do with a self-inflicted injury and was more consistent with a homicide,” said retired Denver detective Jon Priest.

Nancy’s death came during a troubled time in the couple’s marriage. She had filed for separation and intended to divorce Kurt, her sister tells 48 HOURS.

Within hours of Nancy’s death, Sonnenfeld was arrested for her murder. “I believe that there was a rush to judgment, there was an assumption this was a homicide,” Sonnenfeld’s attorney Carrie Thompson tells Moriarty. Thompson also tells Moriarty that about two weeks after Nancy’s death she found a suicide note, evidence she says police overlooked.

            Shortly before Sonnenfeld was to go on trial, prosecutors suddenly dropped the charge, citing insufficient evidence. But the investigation continued, and with additional evidence in hand, prosecutors refiled the murder charge. By then, Sonnenfeld had moved to Argentina.  There he remarried and launched a campaign to clear his name by giving interviews to local media. And he’s claimed that he saw something while working as a cameraman at Ground Zero that the government wants him to stop talking about.

Sonnenfeld declined to speak with 48 HOURS on camera.

“Kurt Sonnenfeld is definitely gaming the system, though someday, hopefully, that game will run out,” says former Colorado Governor Bill Owens.
