In a breakthrough nearly 50 years in the making, authorities have finally identified the remains of a teenage homicide victim discovered in a shallow grave at a California vineyard.
On July 28, the Kern County Sheriff’s Office revealed that the 15-year-old girl, who had long remained unidentified, was Michelle “Shelley” Louise Collier. This identification was made possible through forensic investigative genetic genealogy (FIGG).
The sheriff’s office expressed in their statement that, while the investigation is ongoing, the discovery brings much-needed closure to a family that has spent decades in uncertainty about their beloved’s fate.
What Happened to Missing Teen Michelle Collier?
Detective Ashley Thompson of the Kern County Sheriff’s department shared during a press conference that Collier vanished from her home in Fresno in February 1978, leaving behind unanswered questions.
Fast forward four months, authorities found the remains of the then-unidentified female buried in a vineyard in Arvin, near South Wheeler Ridge Road, a grim discovery that has haunted investigators until now.
The victim—known for decades only as Jane Doe—died of a homicide.
At the time, the sheriff’s office said DNA did not exist and they had to rely on fingerprints and dental records which were unsuccessful in providing any clues to the teen’s identity.
“The case was revisited numerous times. Despite the efforts of detectives and forensic specialists, her identity remained unknown,” Thompson said. “Without her identity, there were no leads, no suspects and no arrests.”
Michelle Collier Identified Through Forensic Investigative Genetic Genealogy
In 2007, the coroner discovered that DNA samples had not been collected in 1978 and exhumed the teen’s remains to recover a DNA sample.
“The specimen was submitted to the California Department of Justice,” the sheriff’s office noted, “but without any available family reference DNA in existing databases, no match could be made, and traditional investigative avenues were exhausted.”
They finally got the break in the case after joining forces with the private genetic genealogy firm Othram to use forensic investigative genetic genealogy.
“FIGG is a powerful investigative tool that combines advanced DNA analysis with traditional genealogical research,” Thompson said. “It has helped generate new leads in cases that had long reached investigative dead ends and opened doors that were not available decades ago.”
Through FIGG, they were able to positively identify the remains as Collier.
“Although today’s announcement marks a significant milestone, our work is not over,” Thompson said. “Identifying Michelle is an important step, but the circumstances surrounding her death remains unknown.”
She added that having the victim’s identity will now give law enforcement authorities the ability to narrow down potential suspects in the case.
“You Will Be Found” Michelle Collier’s Sister Tells Her Killer
Collier’s older sister Cynthia Dunbar thanked investigators and the coroner’s office for their work to identify the family’s loved one.
“She disappeared 48 years ago, and it was only recently that we knew where she was,” Dunbar said at the press conference. “At least with this information, my family has some closure.”
She said the family now can “bring our sister home and have her proper burial.”
Dunbar also had a message for her sister’s killer.
“To the person who killed our sister: The shock of finding out we lost our sister to a homicide is overwhelming to our entire family, especially our 85-year-old mother Maria,” Dunbar said. “Your cowardice act affected our entire family, but make no mistake: Law enforcement will find you and hold you accountable. Whether you are already incarcerated or dead, you will be found. May God bless your soul, because you are going to hell.”
She concluded with an emotional message to her sister.
“You didn’t deserve to die this way, Shelley,” she said. “Barely 15 years old, still a child, with your whole life ahead of you. I’m sorry that we didn’t protect you.”
