Former NBA all-star Ralph Sampson has tentatively agreed to plead guilty to a perjury charge and will serve two months in jail.  Sampson tussled with federal prosecutors in Northern Virginia in 2005 when he was charged with failing to pay over $250,000 in child support for two of his children.  After entering a guilty plea to that charge, he was then indicted on perjury, false statement, and mail fraud charges related to his financial filings in that case made in connection with a request for court-appointed counsel (see earlier post here).  According to an AP story (here), Sampson will plead guilty to the perjury charge to avoid a trial scheduled to begin on Sept. 7.  He has not been sentenced yet for the earlier child support conviction, and it’s not clear whether the agreement in this prosecution will cover both cases.
