A 65-year-old Arizona woman now faces a Class AA felony murder charge in the death of a newborn baby whose body was discovered behind a North Dakota college campus in April 1981, a cold case cracked open by advances in DNA technology and genetic genealogy that took investigators more than four decades to close.
Nancy Jean Trottier was arrested on April 7 after the Barnes County State Attorney’s Office filed the charge, online jail records reviewed by Breitbart show. She appeared in court Monday and is being held at the Stutsman County Correctional Center. A preliminary hearing and arraignment are scheduled in Barnes County for May 21.
The baby, called “Rebecca” by authorities, was found in a wooded area behind a dormitory on the Valley City State College campus on April 16, 1981, Fox News reported. Her umbilical cord was still attached. A plastic covering was over her face. An autopsy determined the infant had been born alive roughly three days earlier and died from acute asphyxia consistent with suffocation.
Trottier was a student at the school from 1978 to 1982, the very years the baby was born and killed on campus grounds. For nearly four decades, the case sat cold. No suspect. No name for the child. Just a small body and a community left to wonder.
Investigators reopened the case after advances in DNA technology gave them new tools. In 2019, they exhumed Rebecca’s body to extract DNA from her remains, then reburied her. By August 2020, a genetic genealogy report had led to possible relatives of the baby, and the trail pointed toward Nancy Jean Trottier.
In October 2021, investigators interviewed Trottier. Her alleged responses, recorded in court documents, were not a denial. She reportedly told them: “Maybe it was me.” And then: “It could be, maybe it was me.”
Cold cases solved through modern forensic science have become increasingly common in recent years, as genetic genealogy databases and refined DNA extraction methods give law enforcement a second chance at justice decades after the original investigation stalled.
In December 2021, Trottier and her husband provided investigators with DNA samples. The results, which returned in June 2023, were overwhelming. An affidavit cited by the New York Post laid out the statistical conclusion:
“A DNA analysis returned in June 2023 concluded that it is 3.481 quadrillion times more likely that the baby is the biological child of Trottier and her husband than an unrelated individual.”
That number, 3.481 quadrillion, is not a rounding error. It is a statistical wall. The DNA did not merely suggest a connection. It identified the parents.
The gap between the crime and the charge tells its own story. Rebecca was found in April 1981. The case went nowhere for nearly 40 years. Then the exhumation in 2019. The genealogy lead in 2020. The interview in 2021. The DNA confirmation in 2023. And finally, the felony murder charge filed on April 7, more than 44 years after the infant’s death.
Prosecuting crimes this old presents real challenges, as courts have seen in other cold-case murder proceedings where decades of elapsed time complicate evidence handling and courtroom proceedings. But the DNA evidence in this case appears to be the backbone of the prosecution’s theory.
Trottier, who is from Arizona, now sits in a North Dakota jail awaiting her next court date. The charge, Class AA felony murder, is among the most serious in North Dakota’s criminal code.
The affidavit and available reporting leave several questions open. No motive has been publicly stated. The exact circumstances of the birth and the baby’s death, beyond the autopsy finding of suffocation, have not been detailed in the public filings described so far. The role of Trottier’s husband, identified as the baby’s biological father through DNA, remains unclear. He has not been publicly charged.
It is also worth noting the gap between the June 2023 DNA results and the April 2025 filing of the murder charge, a span of nearly two years. What investigators or prosecutors were doing during that window has not been explained in any public account.
Cases like this, where someone vanishes from accountability for decades only to be identified through modern science, remind us that time does not erase the obligation to pursue justice. Whether it is a long-missing person finally located or a suspect finally named, the principle holds: the passage of years does not cancel the debt.
Rebecca had no voice. She was born, she was alive, and within days she was dead, found behind a dormitory with a plastic covering over her face. For 45 years, no one answered for it. Investigators never stopped looking. DNA did what witnesses and leads could not.
Trottier’s May 21 hearing will be the next public chapter. The Barnes County courtroom will decide whether the evidence, built across four decades, anchored by a DNA match of staggering certainty, is enough to proceed to trial. The baby they called Rebecca has waited long enough.
Justice delayed is not always justice denied. Sometimes it just takes 45 years and a lab to catch up with the truth.
