"He wants to get back there as quickly as possible," said Goodman.
Prosecutor David E. Fritchey of the U.S. Organized Crime Strike Force in Philadelphia said Milano would be tried separately on murder and racketeering charges.
He has been a fugitive since he was charged in July 1987, along with Scarfo and seven others, in the September 1985 killing of mob figure Frank "Frankie Flowers" D'Alfonso.
The trial in that case is scheduled to begin in January.
Milano also was named in January 1988 in the broad racketeering indictment that resulted in the conviction last month of Scarfo and 16 other mobsters, and Fritchey said Milano would be tried on the federal rackteering charges.
Milano and his brother, Eugene, were declared fugitives when the murder charges were filed. Eugene Milano, who was arrested in December 1987 at a condominium near Atlantic City, was among the 17 defendants convicted in the racketeering trial last month.
According to police, Nicholas Milano was apprehended after Las Vegas police, at the request of New Jersey State Police, conducted a surveillance of longtime Scarfo friend Anthony Gregorio and saw him on Tuesday in the company of a man who matched the description of Milano.
Las Vegas authorities arrested Milano after he visited Gregorio and was driving away from an apartment complex in a leased gold BMW with an Oregon license plate, police and Fritchey said.
Fritchey said that Milano was carrying false identification papers.
In addition to Scarfo and the Milano brothers, the other defendants in the D'Alfonso murder case are Philip and Frank Narducci, Salvatore and Lawrence Merlino, Francis Iannarella Jr. and Joseph Ligambi.
