DELPHI, Ind. (Network Indiana): The family of two murdered Delphi girls are being careful about getting their hopes up following a possible break in the case.

The remains of Abigail Williams and Libby German were found nearly two years ago, just 100 miles away from the recent arrest of a man on child molestation charges.

Abigail’s mother, Anna Williams, says she’s waiting for police to either connect Charles Eldridge to her daughter’s death or clear him as a suspect.

“Until we know this is the guy… we’re still looking for the guy. That’s where we’re at,” Williams says.

Ever since Eldridge’s mugshot was released, the public has compared his features with a sketch of the suspect believed to be involved in the girls’ murders.

“There’ve been a lot of comparisons done, and… this could just be another tip,” says Libby’s grandfather, Mike Patty, who says he sees some resemblance to Eldridge and the murder suspect’s sketch.

Indiana State Police say tens-of-thousands of tips have come in trying to help solve the case, and they are all investigated, whether it garners media attention or not.
