Illinois ? Some horrified relatives who searched Friday for loved ones’ plots at the historic black cemetery at the center of a gravedigging scheme near Chicago instead found more bones on the grounds, prompting authorities to close the cemetery and treat it as a crime scene.

“I found bones out there, I found individuals wandering aimlessly around” who also found bones, Cook County Sheriff Tom Dart said Friday night in announcing that Burr Oak Cemetery in Alsip would be closed to the public.

Families still will be able to file inquiries at the cemetery, which is the burial place of civil rights-era lynching victim Emmett Till, and Dart said he hoped it would reopen to visitors in five to seven days.
