A heartbreaking case that remained unsolved for nearly 45 years has finally seen a major breakthrough. What once seemed like a mystery with no answers has now taken a dramatic turn, thanks to modern DNA technology. A woman living in Arizona has been arrested and is now facing serious charges connected to the death of a newborn baby found decades ago.
Arrest After 45 Years in Cold Case
Nancy Jean Trottier has been arrested in connection with the death of a newborn baby girl in North Dakota. She appeared in a Barnes County court on April 13, 2026, exactly 45 years after the crime is believed to have taken place.
She is now facing a Class AA felony murder charge, which is the most serious murder charge under North Dakota law. The court has set her bond at $750,000 in cash or $2,000,000 through a surety bond. As part of her release conditions, she is also required to wear a GPS monitor at her own expense.
What Happened in 1981
The case dates back to April 1981. On April 16 of that year, the body of a newborn baby girl was discovered in a wooded area on the campus of Valley City State College in North Dakota.
The situation was deeply disturbing. The baby still had her umbilical cord attached, and plastic had been placed over her face. A day later, an autopsy confirmed that the baby had been born alive but died due to acute asphyxia, meaning she was suffocated.
Before burying her, police gave the baby a name, calling her “Rebecca,” as her real identity was unknown at the time.
Years of Mystery and No Leads
For many years, the case remained unsolved. Investigators followed different leads, but none provided enough evidence to identify either the baby or the person responsible.
The lack of technology at the time made it extremely difficult to move forward. As years passed, the case slowly turned cold, with little hope of finding answers.
DNA Technology Changes Everything
The case was reopened in 2019 when investigators decided to use advanced DNA technology. They exhumed the baby’s remains and sent DNA samples for detailed testing, including genealogical analysis.
In 2020, a genetic genealogy report identified possible family connections. These findings helped narrow down potential suspects and eventually led investigators to Nancy Trottier.
Further testing by the North Dakota State Crime Lab in 2023 confirmed a strong biological link. According to investigators, the results showed that it is nearly impossible for anyone other than Trottier and her husband to be the baby’s biological parents.
Evidence and Statements
During the investigation, Trottier was interviewed in 2021. Reports say that she made uncertain statements, including saying, “Maybe it was me” and “It could be, maybe it was me.”
Later that year, she and her husband both agreed to provide DNA samples. A forensic report in 2023 found that her DNA matched evidence collected from the scene, including tissue paper recovered during the original investigation.
Connection to the Location
Investigators also found that Trottier had a direct connection to the area where the baby was discovered. She attended Valley City State College between 1978 and 1982, which places her at the location around the time the incident happened.
This detail further strengthened the case against her.
What Happens Next
Trottier is now facing legal proceedings in North Dakota. Her arraignment and preliminary hearing have been scheduled for May 21, 2026, in Barnes County.
As the case moves forward, more details are expected to come out in court. The legal process will determine her responsibility in the case based on the evidence presented.
