Six weeks into their case, investigators say there's still plenty of hope of catching the killer of two Delphi girls. Police said they've interviewed 300 suspects, but have yet to find the man who killed Libby German and Abby Williams.

Investigators say they are making progress in the case and they continue to work through the numerous tips they have received. Police have also reportedly started to scale back resources but that is due to the number of tips becoming more manageable and no longer needing the additional help.
