The Georgia sun scorched the slab of concrete beneath Juan Carlos Ramirez Bibiano’s body when nurses found him in a puddle of his own excrement, vomiting, according to a complaint.

Officers left Ramirez in an outdoor cell at Telfair State Prison on July 20, 2023, for five hours without water, shade or ice, even as the outside temperature climbed to 96 degrees by the afternoon, according to a lawsuit brought by his family. That evening, the complaint says, Ramirez died of heart and lung failure caused by heat exposure. He was 27.

Ramirez’s family, including his mother, Norma Bibiano, announced a lawsuit against the Georgia Department of Corrections on Thursday, alleging that officers’ negligent performance of their duties caused his death. The warden directed officers to check on inmates, bring them water and ice and limit their time outside, the complaint says.

The Department of Corrections reported that Ramirez died of natural causes, Jeff Filipovits, one of Norma Bibiano’s attorneys, said at a news conference in Decatur, a suburb of Atlanta.
