Woman, 65, Charged in 1981 'Baby Rebecca' Cold Case After DNA Breakthrough
A 65-year-old woman has been charged with murder in connection with the decades-old "Baby Rebecca" case from April 1981, marking a dramatic breakthrough in one of North Dakota's most infamous cold cases. Nancy Jean Trottier, from Sun Lakes, Arizona, faces a Class AA felony murder charge after advanced DNA testing provided what authorities describe as overwhelming evidence linking her to the infant's death.
The Tragic Discovery and Initial Investigation
The case began on April 13, 1981, when the body of a newborn girl was discovered in a wooded area on the Valley City State College campus in North Dakota. The infant, who authorities later named Rebecca, was found with a plastic covering over her face and her umbilical cord still attached, according to documents from the North Dakota Bureau of Criminal Investigation. An autopsy revealed the baby showed signs of "acute asphyxia" and had been dead for approximately 24 to 72 hours, leading investigators to believe she was suffocated shortly after birth.
For decades, law enforcement struggled to identify either the infant or a suspect. Rebecca was given her name by authorities in 1981 before her burial, and items found near her body containing biological material were sent to the FBI for analysis. However, without modern forensic technology, the case remained unsolved, haunting the small community of Valley City.
DNA Technology Unlocks the Case
In 2019, the Valley City Police Department and the North Dakota Bureau of Criminal Investigation decided to revisit the case, leveraging advancements in DNA technology. Rebecca's body was exhumed, and extensive genetic testing was conducted to identify possible relatives. This led investigators to Trottier, who had attended Valley City State College from 1978 to 1982.
During a 2021 interview, Trottier made a cryptic statement to authorities, saying "maybe it was me" when questioned about the case. She consented to providing a DNA sample, and another sample was obtained from her husband through a search warrant. The results were staggering: testing showed it is 3.481 quadrillion times more likely that Rebecca is the biological child of Trottier and her husband than an unrelated individual.
Furthermore, Trottier's DNA was consistent with biological material found near Rebecca's body, which had been handed over to the North Dakota State Crime Lab in 2005. Her husband's DNA was excluded from items at the scene, strengthening the case against her.
Legal Proceedings and Community Reaction
Barnes County State's Attorney Tonya Duffy confirmed the charges during a press conference on April 13, 2026, describing the evidence as "strong." Trottier is currently being held at the Stutsman County Correctional Center with bond set at $750,000. Her attorney, Luke Heck, disputed the strength of the case during a court hearing, arguing that the charges are not as solid as prosecutors claim.
A preliminary hearing and arraignment are scheduled for May 21, according to online court records. The community of Valley City, which has lived with this mystery for over four decades, expressed relief at the development. Lance Peterson, a longtime resident who was a high school senior when the case began, told local media, "She's here now, we're at the cemetery. Yeah, it's good closure for Valley City."
The Independent has reached out to Luke Heck for further comment on the defense's strategy. This case highlights how modern forensic science can breathe new life into cold cases, providing answers where none seemed possible for generations.
