She Was 'Chelsea Jane Doe' for 26 Years. DNA Gave Her Back Her Name.

By Dana Whitfield. Aug 4, 2026

For 26 years, investigators knew her only as Chelsea Jane Doe. Her killer had already been convicted, but the murdered 16-year-old still had no name until preserved DNA led investigators back to a family that had been searching for her.

Her Family Reported Her Missing

Tiffany Bradley’s family reported her missing in Pennsylvania after she disappeared in November 2000. But that report was never connected to the unidentified remains found days later in Chelsea, Massachusetts. For more than two decades, her relatives did not know that the victim called Chelsea Jane Doe was Tiffany.

How Genetic Genealogy Found What 26 Years Could Not

The case was eventually transferred to investigators using investigative genetic genealogy - a technique that combines DNA analysis with traditional genealogical research to build a family tree from an unidentified person’s genetic profile. The method has been used for more than a decade to identify suspects in cold cases. In recent years, investigators have begun applying the same tools to identify victims.

Analysts developed a genetic profile from preserved evidence and used genealogical research to identify possible relatives. Investigators eventually located a close family connection, and direct DNA testing confirmed that Chelsea Jane Doe was Tiffany Bradley.

Authorities formally announced the identification on June 3, 2026. The breakthrough involved the FBI, Massachusetts State Police, Chelsea police, the Suffolk County District Attorney’s Office, and the forensic genealogy company Othram.

The Killer Was Convicted Without Knowing Her Name

Eugene McCollom had already pleaded guilty to killing Tiffany and was serving a life sentence. The case was unusual because investigators knew the killer’s name long before they knew the victim’s. Genetic genealogy finally resolved the remaining question of who she was.

‘Thank You for Not Letting My Baby Be a Box on a Shelf’

Tiffany Bradley’s aunt Janet Bradley-Knight addressed investigators at the announcement event. ‘I want to thank you from the bottom of my heart for not letting my baby be a box on a shelf,’ she said. ‘Thank you for letting us take her safely home.’ Investigators have not released additional details about the circumstances of Tiffany’s death or how she came to be in Chelsea. Her family can now bury her with her name.
