LANSDALE, Pa. - Twenty years ago a teenage year old girl vanished from a Montgomery County train station.
Her body was later found. Her killer was not.
Now investigators hope cold hard cash will help them crack the case.
The DA says the 1993 death of Julie Barnyock was recently re-examined and led to some new leads.
Now investigators are hoping a $10,000 reward will finally help catch her killer.
On November 8, 1993 Julie Barnyock, 18, stepped off the R5 train in Lansdale.
At 11:40 pm she called her father in New Britain, Bucks County to come pick her up.
It would be the last time her father would hear her voice.
"It wasn't until nearly a month later, December 2, 1993 when Julie's body was found hidden in the back area of the Lansdale train station," said Montgomery County District Attorney Risa Vetri Ferman.
Ferman says Barnyock was last seen talking to a white man in his 20's or 30's.
Over the years, investigators have developed suspects and new leads but none have led to an arrest.
Now the DA is taking another look at the case and is relying on tools that weren't available in the past.
"Is there anything anybody missed, is there anything that is in the file that perhaps we couldn't look at 20 years ago, that we didn't have the technology to test 20 years ago and we are just completely starting from scratch," said Ferman.
The DA says new information about the case has been found and new persons of interest identified.
Now investigators are hoping a $10,000 reward will help bring a killer to justice.
"The individual or individuals involved in this must have over 20 years said something to someone. There is someone out there who knows what happened to Julie Barnyock," said Ferman.
If you have information about the death of Julie Barnyock you are urged to call the Montgomery County District Attorney's office or the Lansdale Police.
