Suffolk County District Attorney Ray Tierney announced Friday that the "Fire Island Jane Doe" who went missing in 1996 was Karen Virgata.

The company called "Othram" tells News 12 that normal DNA profiling uses 20 markers to identify a person. They say their technology used hundreds of thousands of markers.

"We can take any type of evidence - sometimes every very old, skeletal remains from an unidentified person," says David Mittleman, of Othram. "We can take these remains and build a very different profile from the kinds of profiles used today."

News 12 is told the DNA technology tries to find a person's nearest relative to give police a better profile of who the person is.
