Federal attorneys are asking for another extension of an order to prevent stripper king Frank Colacurcio Sr. and associates from selling or “destroying” their interests in Seattle-area strip club operations so a grand jury can wind up its investigation into allegations of racketeering and prostitution at the clubs. Colacurcio et al have agreed not to oppose the extension of the order, according to papers filed last week, as they and their attorneys wade through the evidence that led to the government’s claims last year. The U.S. at first opposed the release of – then quietly turned over – transcripts and recordings from wiretaps collected during the undercover operation. If the feds’ case against the family’s empire is proved, the government plans to seize Colacurcio clubs in Seattle, Shoreline and Everett as well as offices in Lake City. Among the possible outcomes, according to a source familiar with the probe, is a settlement that would require Colacurcio, 91, and associates to sell off the properties and get out of the strip club business. No charges have yet been filed, though the U.S. has revealed the three-year investigation and allegations in court documents. The grand jury is expected to wind up its probe by the end of August.
