There had been some hope in the Molly Bish case.
The teenager disappeared from Comins Pond in Warren 22 years ago.
Her remains were found several years later.
Investigators had targeted a man by the name of Frank Sumner who died some five years ago as a person of interest.
Well investigators had collected familial DNA from Sumner's son who is in a prison in Ohio hoping for a break through.
The Worcester DA's office says there was no match but the investigation is continuing.
Heather Bish-- Molly's sister says the family is disappointed but is keeping up hope that somehow there is evidence that will lead to Molly's killer.
