A young white female’s partially decomposed body was found along Interstate 81 in Greene County, Tennessee on April 14, 1985. Examiners estimated she had been dead three to six weeks and recorded severe blunt-force trauma, a possible stab wound, and a fatal blow to the head. Fingerprints and DNA were obtained but yielded no matches for decades, leaving her as a Jane Doe.

The Jane Doe was identified as 17-year-old Elizabeth Lamotte of Manchester, New Hampshire. Lamotte had disappeared on November 22, 1984 after leaving a youth development center; she was not reported missing until 2017. New Hampshire detectives obtained family DNA, entered it into CODIS, and in November 2018 matched it to the Tennessee remains.

The homicide remains unsolved. Investigators continue to seek information about who Lamotte might have been with in the days before her death. If anyone knew Elizabeth or saw her in late November 1984, contact the investigating agency with any details.
