Michelle Louise Collier, a 15-year-old who disappeared from Fresno in February 1978, has been identified as the unidentified homicide victim found buried in a shallow grave in a California vineyard nearly 50 years ago. Collier had been known only as "Arvin Jane Doe" since her skeletal remains were discovered by a tractor operator in a vineyard near Arvin on June 21, 1978.
Her identification, confirmed in October 2025, brings a measure of closure to her family, who had spent nearly five decades wondering about her fate. "At least with this information, my family has some closure," said her older sister, Cynthia Dunbar, during a news conference. Dunbar also addressed the perpetrator, stating, "To the person who killed our sister, your cowardice act affected our entire family. But make no mistake, law enforcement will find you and hold you accountable."
An autopsy at the time of discovery determined the manner of death was homicide, but the exact cause could not be ascertained, and the case stalled without a victim identification. "Without an identity for the victim, the case went cold," said Kern County homicide Detective Ashley Thompson. "For 48 years, detectives knew her only as Jane Doe."
Generations of investigators worked on the cold case. The remains were buried in Arvin Cemetery in November 1978, but the case was reopened as forensic science advanced. In 2007, the remains were exhumed for DNA collection, which was submitted to the California Department of Justice, but without a familial match, identification remained elusive.
A forensic anthropologist examined the remains in 2008, estimating the victim's age to be between 15 and 24. The National Center for Missing and Exploited Children produced a facial reconstruction, but leads did not emerge.
The breakthrough came when investigators utilized forensic investigative genetic genealogy in 2025. Working with the laboratory Othram, a DNA profile was developed, and potential relatives were identified. A DNA swab from Collier's family confirmed her identity in October 2025. DNA previously submitted to a genealogy database by Collier's half-brother, sister-in-law, and cousin aided the process.
In April 2026, Collier's remains were returned to her family. "You didn’t deserve to die this way, Shelley. Barely 15 years old, still a child, with your whole life ahead of you," Dunbar said, using her sister's nickname. "I’m sorry that we didn’t protect you, but you’re with Daddy now in heaven, just as you always wanted."
While the identification is a significant development, the homicide investigation is ongoing. "Identifying Michelle is an important step, but the circumstances surrounding her death remain unknown," Thompson stated. Authorities are seeking information from anyone who knew Collier or has details about her disappearance or death.
