Former St. Tammany Sheriff Jack Strain was back in a courtroom yesterday to plead not guilty to criminal charges. Strain entered his not guilty plea during arraignment in federal court in New Orleans on 16 counts of corruption, including fraud and bribery. It came less than a month after he pleaded not guilty to sex crimes in state court in St. Tammany. The federal case against the 56 YO Strain deals with an alleged kickback scheme at a work-release program in Slidell that he turned over to a private company while he was sheriff. Strain will remain free on an unsecured bond of $1 million on the federal charges. He cannot leave Louisiana and had to surrender his passport. His case will be tried before a U.S. District Judge with a Nov. 12th trial date.
