Symphony of Joliet spokeswoman Lauryn Allison said that privacy laws prevented her from providing any more information about the staff member. But Lakendel Evans told The (Joliet) Herald-News that her mother, Sandra Green, a 57-year-old certified nursing assistant, died at a Joliet hospital after spending 24 days on a ventilator.
Symphony of Joliet has been a focus amid the growing number of cases at the state's long-term care facilities, and last week's announcement prompted the city's mayor to call for a state investigation of the facility.

Over the weekend, Gov. J.B. Pritzker's administration released information about individual facilities. That data showed that Symphony of Joliet and Windsor Manor of Carol Stream each had 81 COVID-19 cases, more than any such facility in Illinois. The data also showed that 286 coronavirus-related deaths - nearly a quarter of the state's total - were linked to long-term care facilities.

Joliet Mayor Bob O'Dekirk says he's asked the Illinois Department of Public Health to get to the bottom of it.
"We don't have the answers right now, but we're going to get the answers. Certainly, Joliet families and people who lost their loved ones have a right to get those answers," O'Dekirk said.
