FORT WAYNE, IND (Fort Wayne’s NBC) – Yesterday investigators working the Delphi murders renewed hope and pleaded for answers in the deaths of Abby Williams and Libby German.

Investigators say it’s not a cold case and they are confident justice will be served.

Two years ago their bodies were found on a trail in Delphi, Indiana.

Today, words of encouragement were spread from one mother to another, both who have experienced an unbelievable tragedy.

Janet Tinsley, the mother of April, the Fort Wayne girl who was murdered in 1988, waited 30 years for her daughters killer to be caught.

Her killer, John D. Miller, was caught with the help of new DNA technology.

He’s now serving an 80-year sentence for that crime, but how did Janet remain hopeful for all those years?

She say’s at times it was hard, but she always knew someday her daughter’s killer would be caught.

Now she’s sharing a message to the mothers of Abby and Libby.

“It may not be 30 years, it might just be another 6 months, might be another year,” Janet continued by saying, “The main thing, don’t ever give up. I mean it took me 30 years to get what I wanted, it’s only been two. I can relate to how they are feeling, the main thing, I can’t say it enough. Just don’t give up.”

Janet also talked about, with the help of new DNA technology, she feels confident the girls’ families won’t have to wait as long as she did.

Investigators are offering up a $225,000 reward for information that leads to an arrest.
