I do think there is some forensic evidence available, possibly DNA, being analyzed by the Indiana state lab and by the FBI in their Quantico location. I quoted news media earlier today about that.
I did want to know more about what evidence is analyzed at the Quantico lab.

A lot!
For our Delphi girls, and the samples or evidence sent to Quantico, I look at DNA casework, including CODIS, latent fingerprints, scientific response and analysis, and crime scene documentation as possibilities of where they could be helping the local and state investigators.
Today, I am wondering if a link may have been found to another crime, with another unidentified person of interest.
Please hold on. I hope it's DNA and see nothing in the media in interviews with the investigators involved at any level precisely saying it's not.
