A school portrait of Michelle Louise Collier, who vanished from Fresno at the age of 15 in February 1978. Michelle Collier vanished in 1978 and became California's 'Arvin Jane Doe' Decades of investigation finally led to a DNA breakthrough Forensic genetic genealogy finally gave the teenager her name back Family delivers an emotional message to Michelle's killer Michelle was finally brought home after nearly five decades The murder investigation has entered a new chapter How forensic genealogy is transforming decades-old cold cases Nearly five decades after a teenage girl was discovered buried in a shallow grave beneath a California vineyard, investigators have finally restored her identity through advances in forensic DNA technology. The victim, known only as "Arvin Jane Doe" for 48 years, has been identified as Michelle Louise Collier, who disappeared from Fresno at the age of 15 in February 1978. Her identification has brought long-awaited answers to a grieving family that spent decades wondering what had happened to her. While the breakthrough offers a measure of closure, it has also reignited a cold-case homicide investigation as authorities work to uncover who killed the teenager and why.Michelle Louise Collier disappeared from Fresno, California, in February 1978 when she was just 15 years old.

Four months later, on June 21, a tractor operator cultivating a vineyard near South Wheeler Ridge Road outside Arvin uncovered skeletal remains buried in a shallow grave. An autopsy determined the victim had been murdered, but investigators were unable to identify her using the forensic techniques available at the time.With no name to pursue, the case gradually went cold and the teenager became known simply as "Arvin Jane Doe."Investigators never stopped revisiting the case as forensic science continued to advance. In 2007, Michelle's remains were exhumed from Arvin Cemetery so detectives could obtain a DNA sample, but the technology and available databases still could not identify her. A forensic anthropologist later estimated that the victim was between 15 and 24 years old, while the Center for Missing & Exploited Children created a facial reconstruction in the hope that someone would recognise her. Despite those efforts, the mystery remained unsolved for years.The breakthrough came in 2025 when the Kern County Sheriff's Office partnered with Texas-based forensic laboratory Othram to use forensic investigative genetic genealogy. Scientists developed a comprehensive DNA profile from Michelle's remains and traced potential relatives through genealogy databases. Detectives then collected a DNA sample from her mother, Maria Collier, confirming that the unidentified homicide victim was her missing daughter.
