An anonymous donation of $100,000 will be used to up the reward for anyone who can provide information that leads to the arrest and conviction of the person responsible for killing Abigail Williams and Liberty German in Delphi.
“We want to thank the public for your continued desire to help solve this case,” Indiana State Police said in a statement, noting investigators are “still actively working on” solving the crime “every day.”
The bodies of Williams, 13, and 14-year-old German were found on Valentine’s Day in 2017, one day after they went missing while at a recreational area.
Their cases have become known as the "Delphi murders."
Before the teens' deaths, German used her cell phone to capture video of a man police now consider the prime suspect as well as an audio recording of a male voice telling the girls, “Down the hill.”
Indiana State Police Sgt. Kim Riley has said detectives believe that whoever killed the girls is from around Delphi, visits frequently, or has been to the area more than once since he seemed to know “the terrain and the location” where the victims died, the Indy Star reported.
Anyone with information about this crime is encouraged to contact law enforcement by utilizing the TIP HOTLINE: firstname.lastname@example.org or calling 844-459-5786.
Police requested that those who provide tips give as much information available as possible, such as the full name of the person of interest, their date of birth or approximate age, physical description, address, vehicle information, why they could be involved and if they have a connection to Delphi.
The total reward now sits at $325,000.
