In December, Greenblatt indicated that Kirsch, 22, and Anderton, 25, would probably seek a plea bargain.
"From the information I have, they're both responsible for this," he said in news reports.
"Taking the credit information from someone who lives across the hall from you - how anyone thinks they can get away with that kind of stupidity for more than a few months is beyond me," Greenblatt said then.
"They know how much trouble they're in. This is a stressful time for them."
And the angst might go up a notch for Kirsch and Anderton.
Local charges against the couple probably will be dropped and federal charges would then be applied, in the upcoming weeks or beyond, according to sources familiar with the case.
But, to date, it's a city case.
Philadelphia police said last month that the FBI would assist in examining the hard drives from four computers found in the pair's third-floor, $3,000-a-month, two-bedroom apartment in the Belgravia, on Chestnut Street near 18th, Center City.
Anderton and Kirsch, arrested in November and December, were charged with identity theft, burglary, unlawful use of a computer, forgery and other crimes.
Anderton, a 2005 Penn graduate with a degree in economics and Kirsch, who has been suspended from Drexel, are out on bail.
They have a preliminary hearing in Common Pleas court Feb. 12.
Police confiscated computer spyware, three lock boxes, nearly $18,000 in cash and counterfeit driver's licenses from several states in the pair's apartment.
Investigators also found credit cards and one passport in the names of some of their neighbors.
The couple is believed to have used the signature from the passport on one of the fake driver's licenses, police said.
The luxury-lovin' pair traveled the world - Paris, London and Turks and Caicos, to name a few locales - police said.
