Delphi needs to put a phone call into Fishers' LE to see if they can help the case using their new equipment. Maybe it still does just the same process as CODIS but is just faster. He says if old crime scene evidence is preserved properly, there's still a chance that they can do something.

The department can now test for DNA in just 90 minutes.
The new equipment, which is manufactured by Thermo Fisher Scientific, is helping the Fishers Police Department generate leads and identify suspects faster.

Detective Sgt. Jim Hawkins of Fishers said, “The criminal forensics investigators will come in, take their crime scene samples or suspect samples. They’ll put it into a cartridge. It’ll go into the instrument itself here and then the software will tell us if we have a DNA profile and, if so, does it match to an existing case.”

Hawkins said, “What the presumptive positive test will allow us to do is to make sure the night or day of the offense that we can confirm that we do have the correct suspect and we do have a match to the crime scene DNA, but we also follow that up with conventional DNA for the court process.”

Just a caveat, this technology might not be all it's touted to be: 'Rapid DNA' promises breakthroughs in solving crimes. So why does it face a backlash?
I believe in Nevada they are looking into whether it should be used for higher level crimes like rape or murder at all, because of concerns about its accuracy. With this technology, the rapid DNA tests are run by law enforcement officers instead of trained forensic scientists so there is criticism that tests like this, performed outside of a forensic laboratory, may not be accurate enough to even follow through with conventional testing. One of the biggest reasons that contribute to this criticism, is that the technology does not work well on complex mixtures of DNA, as would be seen in most sexual assaults and in murders like Delphi, where the girls were even wearing borrowed outerwear. From the article:
There is no question the devices work well on “single-source DNA,” genetic material that comes from a single person. The problem comes when there is a mixture of DNA from multiple individuals, said Vincent A. Figarelli, superintendent of Arizona’s Crime Laboratory System. In those situations, a trained forensic scientist is needed to interpret it.
“Mixture interpretation is the most difficult thing that crime laboratory analysts have to do by far,” Figarelli said. “There’s no way you want a Rapid DNA operator doing a mixture analysis.”
There is also a greater chance that rapid DNA testing will consume the entire sample available for testing, meaning that conventional laboratory analysis would not be possible after the fact or by the defense team at trial.
