Thirty years later, the Livingston County Sheriff’s Department is not giving up on solving a mystery. A girl was killed and dumped in a field Nov. 10, 1979.

She is somebody's daughter. That is why investigators do not give up. And it is the reason they keep this morgue photo in the public eye. It may be the only way for someone to identify her.

“It's a member of somebody's family, (and) until we hold people responsible we're going to continue to remind the community each and every year,” said Major James Szczesniak.

When Szczesniak took over the criminal investigative unit this year, he took charge of the case. He has had to become familiar with the cabinets full of data on Jane Doe.

A farmer found a girl in her teens in a field in Caledonia 30 years ago. She was shot twice: first in the back, then in the head.

She is remembered by a gravestone in Dansville, but there is still no name on the marker. “On today's world, for us to not be able to identify a victim in 30 years, is difficult for me to understand,” Szczesniak said.

Improvements in technology have helped the case move forward. With imaging enhancement tools, this photo was produced. It is what Jane Doe may have looked like before her death. And it is technology helping investigators get the word out. “Our communication is much broader,” Szczesniak said. “We hear a lot more...we get tips continuously through the Internet.”

Investigators still receive about half a dozen tips each month. Altogether, they have followed up on thousands of leads. Szczesniak says it will only take one to finally solve the case. “The answers are there, and it's just a matter of finding the right person and having contact with the right information to put it together.”
