The Tennessee Bureau of Investigation has identified the victim of a Greene County homicide that happened decades ago. 

According to TBI, the body of 17-year-old Elizabeth Lamotte of New Hampshire was found partially decomposed along Interstate 81 near Exit 44 back in April 1985. Her death was ruled a homicide but investigators were unable to identify her.

“Elizabeth Lamotte was 17 years old at the time of her death,” said Brandon Elkins, TBI Special Agent. “She was five feet five inches. She was between 110 and 125 pounds. She had brown hair and hazel eyes.”

An autopsy revealed her cause of death was trauma to the head. Her body was found two to three weeks after she died.

In 2006, they entered Lamotte’s DNA information into a national database, hoping it would lead to her being identified.

This week, investigators confirmed there was a DNA match and were finally able to identify her remains. According to TBI, it wasn’t until last year that New Hampshire police obtained DNA samples from family members. 

TBI says Lamotte was reported missing in New Hampshire.  She was last seen in Manchester, New Hampshire on November 22, 1984. New Hampshire’s Attorney General said Elizabeth Lamotte left a youth detention center in  Manchester, New Hampshire and seemingly vanished.

Investigators are asking for the public’s help solving the decades-old case. Anyone with information is asked to contact TBI at 1-800-TBI-FIND.
