An investigator traveled to Nebraska last week to meet with a woman who may be related to the victim. Her sister ran away from home and has been missing since.

Boulder sheriff's Detective Steven Ainsworth told CBS 4 News that authorities hope to hear this week whether the woman is related to Jane Doe based on DNA testing.

The missing Nebraska woman initially was ruled out because a photo of her face didn't appear to fit the skull of Jane Doe. But Frank Bender, a forensic sculptor who co-founded the Vidocq Society, which brings together renowned forensics experts to try to solve cold cases, looked at the photo and suggested they double-check.

He told Ainsworth there were signs that the skull may match the picture.

Bender created a sculpture of Jane Doe's face and unveiled it last Monday.

Jane Doe was 18 to 20 when her body was found. Hikers discovered her in 1954 as they walked along Boulder Canyon. Police classify the case as a homicide, saying the woman was thrown down a 29-foot highway embankment above Boulder Falls.

Ainsworth declined to release the name or picture of the runaway. After disappearing from her home, the girl never contacted her family, but her parents never gave up hope of finding her, the woman in Nebraska told Ainsworth.

"She told me . . . 'When my dad retired, he and my mom bought a secondhand car, put a mattress in it and traveled all over the country, trying to find her until the money ran out,' " Ainsworth said.

The detective stressed that the Nebraska lead was just one of 20 possible leads that have come in from around the country.

"I had one from New York, one from Wisconsin, one from Tennessee, one from Washington state," he said. "I feel a very, very strong sense of urgency to identify her.

"We'll find out who she is."
