Julie Barnyock would be 38 years old if she were alive today, instead her death investigation is two decades old.
Barnyock was 18 when she went missing from the Lansdale, Pa. train station 20 years ago Friday.
"She took the R-5 and she arrived at Lansdale Train Station after spending the day in in Philadelphia with a friend," Montgomery County District Attorney Risa Vetri Ferman said Friday while flocked by Lansdale law enforcement as they relaunched the cold case investigation by announcing a $10,000 reward.
Ferman said Barnyock was seen talking to a man in his 20s after getting off the train around 11:40 p.m. that night.
"About a half hour after she arrived at the station she called her father," Ferman said. "(She) asked him to pick her up, asked for a ride home. Shortly thereafter her father came from New Britain Township in Bucks County... and could not find his daughter."
Barnyock's father went home and reported her missing the next morning to New Britain Police.
Police launched a missing person search as her family kept hoping that she was still alive.
It wasn't until Dec. 2, 1993 that Barnyock's decomposing body was found in the adjacent train yard.
Her killer has never been brought to justice.
Despite hundreds of manpower hours, forensic tools and interviews, Ferman said "at this point and time we have still not been able to solve this case."
No one has ever been charged in the case -- something Ferman and investigators hope to change.
Recently investigators reopened the case and they hope the reward money helps in the investigation.
"The reason we are announcing this award is simply the hope that there is someone out there who has information on this case -- perhaps someone who has been confiding in by a person close to them," Ferman said. "We are hopeful that this reward and perhaps some conscience will compel someone to share this information with law enforcement."
Ferman said that she hopes people who know persons of interest in the case will come forward with information.
SEPTA is also helping out by posting flyers on trains.
Anyone with information should contact the Lansdale Police Department.
