The parents 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 it has been difficult to see the case go unsolved for so long. Ever since the mugshot was released, the public has compared his features with a sketch of the suspect believed to be involved in the girls’ murders. Indiana State Police say tens-of-thousands of tips have come in trying to help solve the chilling case, and they are all investigated whether it garners media attention or not.
