A worker searches for evidence at Burr Oak Cemetery July 14, 2009 in Alsip, Illinois. Police recently closed the cemetery declaring the site a crime scene after human remains were found on the ground at various locations in the cemetery. Police suspect hundreds of graves could have been dug up in the historic black cemetery over the last several years and the bodies dumped elsewhere on the grounds in order for the gravesites to be resold by the cemetery management. Blues music legend Willie Dixon and civil rights figure Emmett Till are among those buried in the suburban Chicago cemetery. The First Lady's office confirms that Michelle Obama's father, Fraser Robinson, is also buried there. (Photo by Scott Olson/Getty Images)
