In 1968, 14-year-old Sandra Stiver and her sister-in-law, 17-year-old Martha Stiver, went missing from Philadelphia.
"The last time that they were seen, my mom seen them running down the street. They ran from the house," said Hazel Demoss, Stiver's sister.
A couple months later, remains were found at French Creek State Park in Berks County. Back then, investigators did not have the modern-day technology to connect the dots. Plus, the original missing persons report was lost.
"Years go by and you think they're gonna come through the door and they never come," said Tom Stiver, brother of Sandra Stiver and husband of Martha Stiver.
The investigation took a turn a few years ago when Bucks County Coroner Dennis Hess updated the National Missing and Unidentified Persons System. Sandra's sister was browsing the website when she came across a sketch that looked awfully familiar.
After some investigating, officials exhumed the graves of the Jane Does found at the state park.
"The plastic plaque stated unknown female and gave the date that she was buried here. It was great because when we hit that we knew that we had the right girls," Hess said.
A DNA test confirmed it. Now, Sandra Stiver is reunited with her family. Hess released her remains to her family Monday morning.
Martha Stiver's remains are being sent to her family in Kansas.
This case is not closed. It is being investigated as a murder.
"You're sad and then you're mad because we don't know who did it," Demoss said.
"It's tough. Somebody out there's gotta come forward with this. There's no closure to it," Tom Stiver said. "How do you spend 45 years and then find out this happened? Somebody out there knows who did this."
Anyone with information on the death or disappearance of Sandra or Martha Stiver should call state police.
