"We have trips to London, Paris, Hawaii, Turks and Caicos, and Montreal, Canada," Sweeney said, adding that police believe the boyfriend-girlfriend pair has been at work for up to two years, and that they may be responsible for $100,000 in theft. "It's really nice to go on trips when you're not paying for them."
Kirsch and Anderton, who have already been released from custody, will be rearrested on whatever additional charges are filed. It was not immediately clear what attorneys are representing the defendants.
Sweeney said that Kirsch's father came from her hometown in Winston-Salem, N.C., to post a bond and pick up his daughter Sunday. He also said the woman had gotten into some trouble with authorities at Drexel, where she remains listed as a member of the Delta Phi Epsilon sorority.
Neither Kirsch nor Anderton have telephone numbers listed in the Philadelphia directory. A message left by ABC News at the home of Anderton's parents in Washington state was not returned.
A Facebook account created by a Drexel student identified as Niki Vervelli celebrates Kirsch's arrest. Vervelli did not respond to a message from ABC News.
Ian Jacobson, another Drexel coed, posted a comment in reaction to the Facebook group, saying, "and no one believed me when I said she was nuts AND bad news."
