Police released the 911 recordings on Friday of witnesses who passed by the gruesome face-chewing attack on the MacArthur Causeway.
A bus driver who passed by the scene told a 911 operator how Rudy Eugene was beating Ronald Poppo to a pulp, according to the just-released recording.
“Listen, there is a naked man on the MacArthur Causeway at the end of the causeway coming towards Biscayne Boulevard. He is beating another man to a pulp – like on top of the man, beating him, the man is bleeding,” said the bus driver.
She told the dispatcher that she passed by the scene and saw the attack happening.
“He’s beating another man. It’s a naked man beating another man,” the driver said.
She added that the man on top would kill the other man.
Police said they were forced to shoot Eugene, 31, after he brutally attacked Poppo, 65, on the causeway last Saturday, chewing off more than 80 percent of the homeless man’s face.
Another caller tells the dispatcher, "He was taking his clothes off and throwing them into traffic. A black male, curly hair, rastafarian hair. Uh ... goatee. Can't miss him, he's naked."
A male 911 caller reported two men fighting, almost knocking a woman off her bicycle.
Poppo was taken to Jackson Memorial Hospital, where he remains in critical condition.
A Jackson Health System spokesman confirmed Friday that the hospital is investigating after a few graphic photos of Poppo's face emerged on social media earlier in the week.
"Jackson is conducting an investigation to determine whether or not patient privacy was violated," spokesman Edwin O'Dell said in an email.
