Bond was set at $250,000 for Towns, the cemetery's manager, and at $200,000 for the other three. Authorities said Towns also pocketed donations she elicited for an Emmett Till memorial museum. She has not been charged in connection with those allegations. Court documents show she was fired from the cemetery in late May amid allegations of financial wrongdoing.Cook County state's attorney's office spokeswoman Tandra Simonton said Towns is being represented by a private attorney, but Simonton did not know the attorney's name. The Cook County public defender's office said it had not yet assigned attorneys to the other three cases.

The investigation was prompted in May, when a groundskeeper discovered skeletal remains in the part of the cemetery that wasn't supposed to be used, and cemetery officials notified Alsip police. Around the same time, the cemetery's Arizona-based owner, Perpetua Inc., called Cook County authorities to report the alleged financial wrongdoing.

Towns allegedly took cash for new graves, then instructed the three gravediggers to empty existing plots and move the remains inside to an unused part of the cemetery covered with chest-high grass and dotted with trees.

Perpetua Inc., said in a statement Thursday that the company is cooperating with investigators.

"We will make every attempt to insure and maintain the dignity of those that have been entrusted to our care," the company said.

It's the second time in recent years that Burr Oak has been at the center of an investigation. In 2005, the body of the 14-year-old Till, whose slaying in 1955 in Mississippi for allegedly whistling at a white woman helped galvanize the civil rights movement, was exhumed as part of a reopened investigation of his death.

Dart said Till's grave was not disturbed in the alleged plot-selling scheme, but he did not have information about the graves of Washington and others.

One of Till's cousins who lived at the Mississippi home where Till had been staying when he was killed and witnessed the teen being dragged away by two white men, called the Burr Oak scandal "horrific."

"To me, it's just as bad as it was the night they took Emmett," Wheeler Parker said. "Emmett's thing sounded like a nightmare and a dream, and this is the same thing."
