A federal judge in Alexandria yesterday postponed a decision on whether to give defense lawyers the results of an FBI probe into a federal grand jury that indicted three reputed massage parlor owners last month.

Lawyers for the three codefendants -- Louis Michael Parrish and two alleged associates, Larry J. Wadino and Kathy Lynn Caldwell -- asked for access to the FBI documents following reports of a breach of security in the jury's secret proceedings.

But U.S. District Court Judge Oren R. Lewis, who speculated during yesterday's hearing that details of the incident might have been "planted," said he would rule next week after reading the report. Lewis expressed doubts that the incident would affect the validity of the indictments.

The three defendants were charged Jan. 29 with 13 counts of prostitution, racketeering and conspiracy and are scheduled to stand trial March 20.

The reported "leak" in the grand jury surfaced two weeks ago when Wadino's attorney, John Dowd, was told that a female grand juror had met a male witness in a social setting and discussed the investigation.

Although U.S. Attorney William Cummings told the court yesterday that the woman was not present on the day the indictments were drawn up and had been dismissed from the panel as a result of the incident, defense lawyers have raised the question of impropriety in the proceeding.

Defense attorneys also asked yesterday that the trial be moved from Alexandria to Richmond because of extensive pretrial publicity. Lewis deferred ruling on the motion until the time of jury selection.
