"The detective also said there was DNA from an unknown source collected located at several locations at the crime scene, and that one of those pieces was of high enough quality to run through the FBI's Combined DNA Index System (CODIS).
That piece is currently being run through the system, Covelli said, and other DNA found on the scene is being run against DNA swabs the police have collected throughout the investigation."
According to this article, the reporter interpreted what Covelli said as quoted above (she didn't quote Covelli though).
She wrote that multiple samples of the same DNA were found at the scene of which one was a sufficient sample that is currently being tested in CODIS.
Note: No results stated - match or no match.
Other DNA found at the scene is being tested against swabs police have obtained from people.
Note: But the sufficient sample is not being tested against swabs obtained from people?
