WALKER COUNTY - Walker County investigators say they aren't giving up on trying to find out the identity of a girl found along Interstate 45.
35 years ago she arrived in Huntsville and a day later, she was dead.
Detectives are still trying to learn more about who she was.
They recently took the shoes she was wearing that night to run a D-N-A test.
As News 3's Noelle Bellow found out, they are hoping a newly released composite of the young woman will get them closer to finding those answers.
She's only known as Jane Doe.
She is between the ages of 15 and 18, shes about 5'6, 108 pounds, she has brown hair but its kind of a light brown hair, maybe a reddish tint, she has what were described as hazel eyes.
Her body was found in the grass, on the shoulder of IH45, just north of Huntsville, one half mile south of the FM 1696 exit.
"She was strangled with a ligature, it could be a rope, a pair of pants, it could be anything that could be tied around. She was sexually assaulted and nude on the side of the road," said Detective Thomas Bean.
November 1st marked 35 years since a truck driver saw her body on the side of the road, and now, detectives have released a new composite of what she would have looked like.
Bean said, " The National Center for Missing and Exploited Children, had done some composites and so we liked one of the ones that they did. We compared it to the autopsy photos, the scene photos and the color of the hair and facial features are very close."
Detectives believe Jane Doe's body was found about 20 feet off the road, and even though the crime happened more than three decades ago, detectives still come out to the area frequently.
"We literally only have four pictures of where it actually happened, so we come out and try to get a picture of the scene and kind of get an atmosphere of where it happened," said Bean.
Aside from a few people who said they had seen her around town in the days before her body was found, who she is remains a mystery.
"I'm always checking on missing child databases. I'm always looking, I really want to find out who this girl is," said Detective Bean.
Detectives say they don't have any suspects, but they are looking into the possibility of serial killers in the past who have committed similar crimes.
