A teenage girl whose body was found buried in a shallow grave beneath a California vineyard nearly half a century ago has finally been identified, reopening a murder mystery that had gone cold for 48 years.
Michelle Louise Collier was just 15 years old when she disappeared from Fresno in February 1978.
Four months later, a tractor operator cultivating a grape vineyard near Arvin uncovered her skeletal remains buried in a shallow grave, but investigators could not identify the teen, leaving her known only as “Arvin Jane Doe” for nearly five decades.
Her older sister, Cynthia Dunbar, said the family spent nearly 50 years wondering what happened before finally learning Michelle had been the unidentified homicide victim all along.

“She disappeared 48 years ago, and it was only recently that we knew where she was,” Dunbar said during an emotional news conference Wednesday. “At least with this information, my family has some closure.”
Dunbar also delivered a searing message to the person responsible for her sister’s death.

“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,” she said.
“To the person who killed our sister, your cowardice act affected our entire family,” Dunbar continued. “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’re going to hell if you’re not there already.”
Authorities said Collier’s remains were discovered June 21, 1978, near South Wheeler Ridge Road after the tractor operator unearthed the shallow grave.

An autopsy at the time determined the manner of death was homicide, although the exact cause of death could not be determined. Investigators knew they were dealing with a homicide victim, but without an identity, the case stalled.
“Without an identity for the victim, the case went cold,” Kern County homicide Detective Ashley Thompson said. “For 48 years, detectives knew her only as Jane Doe.”
Kern County Sheriff Donny Youngblood said generations of investigators continued revisiting the mystery, including several people who were present at Wednesday’s announcement.
“Several detectives have looked and worked on this case since 1978,” Youngblood said. “These cases are outstanding to us when we come to a resolution, especially for the family members.”
The remains were buried at Arvin Cemetery in November 1978 after investigators were unable to identify them through fingerprints, dental X-rays or other forensic methods available at the time.
The case was reopened multiple times over the following decades as forensic science advanced.

Investigators got another chance in 2007 when the remains were removed from the cemetery so a DNA sample could finally be collected. The sample was submitted to the California Department of Justice, but without matching DNA from relatives, detectives were still unable to identify the teenage victim.
A forensic anthropologist examined the remains in 2008 and concluded the victim was likely between 15 and 24 years old, with evidence pointing toward the younger end of that range.
Detectives also partnered with the National Center for Missing and Exploited Children, which produced a facial reconstruction of the victim and circulated her image publicly. Investigators reviewed fingerprints, dental records and missing-person cases from California and Oregon, but no new leads emerged.
The breakthrough finally came in 2025 when investigators turned to forensic investigative genetic genealogy, a technique that combines advanced DNA analysis with traditional genealogical research to identify unknown victims.
Working with Texas-based forensic laboratory Othram, investigators developed a comprehensive DNA profile from Collier’s remains and identified potential relatives through genetic genealogy.
Collier’s identification marks the 86th publicly announced California case in which investigators used Othram’s forensic genetic genealogy technology to identify previously unknown human remains.
Detectives then contacted members of Collier’s family and obtained a DNA swab to compare with her mother.
In October 2025, the comparison confirmed that the unidentified homicide victim was Maria Collier’s daughter, 15-year-old Michelle Louise Collier.
Dunbar said DNA previously submitted to a genealogy database by Collier’s half-brother, sister-in-law and cousin helped investigators identify her.

After investigators confirmed her identity, Collier’s remains were removed from Arvin Cemetery in April 2026 and returned to her family, allowing them to finally bring the 15-year-old home and give her a proper burial.
“You didn’t deserve to die this way, Shelley,” Dunbar said, using the family’s nickname for Michelle. “Barely 15 years old, still a child, with your whole life ahead of you.”
“I’m sorry that we didn’t protect you, but you’re with Daddy now in heaven, just as you always wanted,” she added. “We love you, Shelley.”
While Collier’s identification marks the biggest break in the case since 1978, investigators stressed that the homicide investigation is entering a new chapter, not ending.
“Identifying Michelle is an important step, but the circumstances surrounding her death remain unknown,” Thompson said.
Authorities said no suspect information was available for public release, but Thompson said identifying the victim fundamentally changes the investigation.
“Now we get to investigate it knowing who the victim is,” Thompson said.
The Kern County Sheriff’s Office is asking anyone who knew Collier or has information about her life, disappearance or death to contact Detective Thompson at 661-861-3110 or the Secret Witness line at 661-322-4040.
