Police in Ohio said the victim in a decades-old murder case may have traveled or have a connection to Connecticut.
They're looking to identify a woman found in a ditch along Greenlee Road just west of Troy, OH.
She was found on April 24, 1981 and been dead for less than two days beforehand.
Investigators estimated that she was in her late teens to early 20s, stood 5'6" tall and weighed 125 pounds.
The victim had long, reddish-brown hair that was styled in two side braids with a part down the middle. She also had freckles on her face.
She had several scars. One was beneath her chin, another was on her left arm, two were on her left wrist, one was on her right hand, one was on her right ankle and one was on her right foot.
She had also been to the dentist before, as was evident by a top right central incisor with a porcelain-metal crown.
The victim was found wearing bell bottom blue jeans, a brown turtleneck sweater with an orange crisscross design on the front and a handmade tan buckskin pullover jacket with leather fringe.
In Feb. 2016, detectives were able to use information from the National Center for Missing & Exploited Children to conduct facial reconstruction with technology. It also sent pollen collected from the victim's clothing to a lab in Houston, TX.
On Sunday, the Miami County Sheriff's Office received the results of the pollen test. Scientists determined that the victim spent a significant amount of time in the northern dry-oak forest region. That includes ares of Connecticut, Pennsylvania, New Jersey, New York, Massachusetts and Rhode Island.
Other pollen samples showed that she also traveled to more arid regions of the western U.S. or northern Mexico.
A high level of soot from vehicle traffic or industrial activity was also on her clothing, which could indicate that she hitchhiked.
Anyone who may recognize the woman is asked to call the Miami County Sheriff's Office at 937-440-3965 ext. 6629 or the Miami County Communication Center at 937-440-9911.
