DELPHI, Ind – A big donation to the Delphi Investigation Reward Fund.

An anonymous donor gave $100,000 to the fund, boosting the total reward amount to $325,000.

The reward is for the person who can provide information leading to an arrest and conviction of whoever who killed Abigail Williams and Liberty German in Feb. 2017.

The bodies of German, 14, and Williams, 13, were found in a rugged area near a hiking trail one day after they vanished while walking on that trail near the Monon High Bridge, just outside their hometown of Delphi, which is about 60 miles northwest of Indianapolis.
