DELPHI, Ind. –The cash reward for information leading to the arrest of a person or people responsible for the murders continues to grow. This weekend investigators received stacks of mail with donations for the reward. After totaling it all up the amount is now over $96,000. That’s an increase of nearly $40,000 since Friday. Police also say they’ve received close to 10,000 tips.

Indiana State Police Sgt. Tony Solcum said nearly every hour, investigators are interviewing potential suspects and witnesses, but they are being ruled out.

“As of right now, that information has been crossing off suspects so it’s been exonerating suspects so to speak, but that in itself is valuable information,” Solcum said.

Once tips are received, the information is recorded into a database. Local law enforcement and more than 20 outside agencies field the tips to determine what is valuable. Some tips have come in from all over the world, including Australia.

Over the weekend, several initiatives were made to draw in more tips for the case. Authorities recorded a radio ad that is being broadcast in all of Indiana, and Indiana State Police stopped drivers in the Delphi area to hand out fliers with pictures and the tip line information.

The Indiana State Police Alliance established an account where people can donate to the reward fund. If you would like to donate, checks should be made payable to the Indiana State Police Alliance Foundation. Put “Delphi Reward” on the memo line and mail your donation to:

Anyone with information in the case should call the Delphi Murder Tip Line at 1-844-459-5786. Tips can also be reported by emailing abbyandlibbytip@cacoshrf.com. Police said information can be reported anonymously.

The line is now manned by the FBI Major Case Contact Center in Washington, D.C. Callers will have to follow a few prompts to report their information.
