PHOTOS: Ohio police are once more appealing for help in IDing a slain Jane Doe teen and finally bringing her killer to justice.
Dubbed also the "Buckskin Girl" for the distinctive overcoat she wore at the time of her death, remains of the unknown victim below were found on April 24, 1981 -- approximately two days after she'd been killed.
Ohio's Jane Doe is estimated to have been in her late teens or early twenties when she brutally died.
In addition to the buckskin leather jacket, she was also wearing bell-bottom slacks and a brown turtleneck.
Investigators believe the young woman might have been hitchhiking when she was picked up by her killer then bludgeoned to death and dumped dead in a ditch near Troy Ohio.
A recent forensic breakthrough has revived interest again in actively pursuing, and ideally solving, her 35-year-old cold case murder, which many people have speculated could be the work of a serial killer still at large.
The ominous theory is supported by the fact that several Ohio women were similarly murdered during the 1980s and 90s, and their bodies (or body parts) deposited throughout the region.
Although most of these other victims reportedly have long ago been identified, their murders also remain unsolved.
For decades in the Jane Doe homicide case, however, authorities had no idea even where the victim originally hailed from, let alone her name.
But at least this aspect of the tragic mystery appears to have been partially solved now: Pollens, native only to the American northeast, and a substantial amount of soot particles, have been recovered from the Buckskin Girl's outer clothing.
Both residues have helped narrow down the likely U.S. states and urban industrial locales where she could have lived in or been visiting for some time, before coming to Ohio in the spring of 1981.
Therefore officials are especially appealing for the public's help in IDing Jane Doe in such states as New York, New Jersey, Connecticut, Pennsylvania, and Rhode Island.
A bit of "southwest pollen" was also detected on the Buckskin Girl's coat, which could indicate she briefly traveled through that section of America en route to Ohio, or even that the garment itself was borrowed.
The Miami County Sheriff’s Office is heading up the renewed investigation into her wrongful death and has distributed the above composite images of what the slain teen probably looked like, including alternate hairstyles.
Anyone who thinks they recognize her, or who has other information relevant to her cold case, should call the MCSO at (937) 440-3865.
