Prosecutors in South Florida on Thursday dropped manslaughter charges against three nursing home employees who were present when 12 patients died from overheating five years ago after power was knocked out from the facility in the aftermath of Hurricane Irma.

The Broward County State Attorney’s Office dismissed the charges against Althia Meggie, Sergo Colin and Tamika Miller, who worked at The Rehabilitation Center at Hollywood Hills

The victims, ranging in age from 57 to 99, had body temperatures of up to 108 degrees, paramedics have reported. The staff has been criticized for not taking the patients to a hospital across the street that had air conditioning.

The group was charged after the patients died due to the facility’s air conditioning system losing power amid sweltering heat three days after Hurricane Irma hit the southern tip of Florida in September 2017

A state report said that before the storm hit on Sept. 10, 2017, Carballo and his staff made appropriate preparations. They purchased extra food and water and seven days’ fuel for the generator.

Eight residents died on Sept. 12-13, and six other people died over the next few weeks. Some of the victims had body temperatures that rose to nearly 108 degrees.

Twelve of the deaths were attributed to the nursing home’s failure to adequately respond to Irma, according to the newspaper.

Caballo’s attorney is accusing prosecutors of ethical misconduct and bad faith for pursuing a case they “know they cannot win
