More than 40 years after the body of a newborn was found in North Dakota, authorities identified a suspect thanks to genetic genealogy. The woman faces charges of felony murder.
The discovery of a lifeless newborn in 1981 on the Valley Metropolis Pronounce Faculty campus marked one of the most enigmatic cases in the state of North Dakota, as reported by Valley Data Live.
The baby, found in a wooded area behind a dorm, still had her umbilical cord attached and a plastic covering had been placed over her face. She was baptized by the authorities as “Rebecca”, since her family was never identified at that time.
According to the autopsy, The girl was born alive a few days before being found and died from asphyxiation, in one case similar to suffocation.
The key: advances in DNA
For decades, The case remained without suspects until it was reopened in 2019 thanks to advances in genetic technology.
Researchers exhumed the baby’s remains and applied genetic genealogy techniques, which made it possible to identify possible family ties.
These tests eventually led to Nancy Jean Trottier, a 65-year-old woman living in Arizona.
The DNA results, obtained in 2023, were key to the case.
According to authorities, it is 3.481 billion times more likely that Trottier and her husband are the biological parents. DNA similar to the accused was also found on an object recovered at the scene.
Besides, During an interview in 2021, the woman reportedly declared through tears: “Maybe it was me.”
Authorities confirmed that Trottier attended the university between 1978 and 1982, a period that coincides with the date of the crime.
For years, the lack of technology prevented progress in the case, which became one of the oldest so-called “cold cases” in the region.
Judicial process
Trottier faces a class AA felony murder charge, one of the most severe in the state.
She is currently being held on $750,000 bail and is due back in court on May 21.
The case represents an example of the impact of modern forensic science in solving historical crimes, providing answers after more than four decades.
