Detroit— from www.detnews.com - Federal prosecutors reversed course today and agreed to let a lawyer review a list of clients from the 248 area code who hired hookers from a high-priced escort service, the attorney said.

The move comes a day after lawyer Paul DeCailly [pictured], who represents Miami Companions escort service co-owner Greg Carr, filed a motion in U.S. District Court in Detroit accusing prosecutors of picking and choosing which Metro Detroit clients would be outed as hiring $500-per-hour prostitutes.

The U.S. Attorney's Office had said DeCailly could review names from only the 313 and 734 area codes, not 248.

The U.S. Attorney's Office sent him a letter today saying it made a mistake in blocking him from reviewing a list of clients from the 248 area code. Prosecutors also will let him view a list of customers from Macomb County and the 586 area code, he said.

The Florida-based lawyer said he will not be satisfied merely reviewing the black book under the watchful eye of an FBI agent. He will continue pushing for a copy and hopes the court will schedule a hearing on his motion soon.

"If I come up (to Michigan), I'm leaving with a copy," he said. "If there is a hearing, I'll be asking that (the black book) be made immediately available."

A U.S. Attorney's Office spokeswoman today confirmed the office sent the letter to DeCailly granting access to the 248 and 586 sections of the black book.

Prosecutors busted the international escort service in July, indicted the owners and three employees on prostitution or money-laundering charges and seized a black book bulging with tens of thousands of customer names, job details and contact information.

Prosecutors have accused Carr and his ex-wife Laurie Carr of running an Internet-based sex empire that dispatched waves of prostitutes to hotels and beachfront villas around the world. The Miami-based ring listed Detroit as one of its busiest stops in the United States.
