(WPTA21) - Thanks to an anonymous donation, the Delphi double murder investigation's reward fund has swelled to $325,000. The Indiana State Police announced Monday that the donor sent the investigators $100,000 to help coax a tipster to come forward to help detectives solve the 2017 murder of two young girls. 14-year-old Liberty German and 13-year-old Abigail Williams disappeared on Feb. 13, 2017, while hiking near their hometown of Delphi. Volunteer searchers found their bodies the next day in a wooded area. Police have also released two sketches of what they believe the suspect may look like.
