As Florida continues to pick up the pieces in the aftermath of Hurricane Irma, more confusion builds around the 11 heat-related deaths at a South Florida nursing home following the storm earlier this month.

But a critical issue — whether or not administrators from the Rehabilitation Center at Hollywood Hills in Broward County made distress calls for help to Gov. Rick Scott’s private cellphone — will likely not be cleared up soon. On Sunday, the Florida governor’s office revealed the four key voice mails from the center have been deleted.

“The voice mails were not retained because the information from each voice mail was collected by the governor’s staff and given to the proper agency for handling,” a Scott spokeswoman said Sunday in a statement. “Every call was returned.”

The administration explained the voice mails fells into the legal category of “transitory messages,” which under state law can be deleted once they “become obsolete or lose administrative value,” the Miami Herald reported. The governor’s office said the calls were promptly returned by state officials, who urged nursing home staff to dial 911 in an emergency.
