The cases against four former employees at the Aledo Wal-Mart move forward in Mercer County Circuit Court. 56 year old Tara J. Speck of Monmouth, 45 year old Robert A. Osborn of Rock Island, 76 year old Paul D. DeWilde of Silvis, and 52 year old Laura E. Diehl of Aledo were arrested last month on controlled substance and forgery counts. The Aledo Police Department was notified by the Asset Protection Manager of Wal-Mart that the company had conducted an internal investigation over the past several months at the Aledo store and that led to the charges. A pre-trial conference has been set for May 19th for Osborn, May 5th for DeWilde, and May 12th for Diehl. A preliminary hearing has been continued to April 7th for Speck.
