MIAMI, Fla. -- Police have released 911 recordings of the horrific attack along a Miami causeway last week that's now being dubbed the "Miami zombie attack."
Officers arrived at the scene to find a naked man chewing off another's man face.
Several vehicles, including buses and even three bicyclists, went past as police say Rudy Eugene, 31, chewed the face off a homeless man named Ronald Poppo.
"He's going to kill that man, I promise you," a female bus driver said, urging a 911 operator to send help. Poppo remains hospitalized.
The driver, who wasn't named by authorities, described the scene as she drove by.
"Listen, there is a naked man on the MacArthur Causeway," she said. "He is beating another man to a pulp — like on top of the man, beating him, the man is bleeding."
Another caller said the two men were fighting, saying they nearly knocked over an elderly bicyclist.
"These two bums were going at it with each other, taking up the whole lane," the caller said. "I think they were fighting or something."
The unidentified man gave his phone number to the 911 operator. He declined to comment when contacted Friday evening by The Associated Press.
A second male caller didn't mention the fight, instead reporting that he saw a man taking off his clothes and throwing them into traffic.
"You can't miss him. He's naked," the man said.
Video footage, taken by security cameras on the Herald building in downtown Miami, shows the entire 18-minute attack, which ended when a police officer shot the attacker after he did not stop his assault on the homeless man.
The video quality is poor, and facial details and the gore of the scene are not visible. But the movements of those involved are. The shooting itself is obscured by the bridge that carries Miami's Metromover tramway over the site of the attack on the MacArthur Causeway.
It's not clear how much of the attack motorists could have seen, as there is a waist-high concrete barrier between the road and the sidewalk where the attack took place, but one of the bicyclists passed on the sidewalk, and one driver slowed down to look at the scene.
The footage shows that Eugene walking along the sidewalk and then stopping in a shaded area created by the tramway bridge. He apparently attacks the victim, dragging him out from the shade, stripping the victim's clothes off and then beating him as the victim kicks his legs in an apparent attempt to fight back.
The attacker then spends several minutes crouched over the victim, including when a bicyclist rolls by on the sidewalk and a white sedan rolls very slowly past the scene.
Police said at least five of those passers-by called to the report the incident, according to the Miami Herald report accompanying the video.
When a patrol car arrives, the officer appears to draw his gun quickly, but the actual shooting is blocked by the tramway overpass.
Larry Vega witnessed the attack and spoke to CNN affiliate WSVN.
"The guy just kept eating the other guy away, like ripping his skin. It was just a blob of blood," he told WSVN.
The arrival of police did not deter the attacker, Fraternal Order of Police President Armando Aguilar told CNN affiliate WPLG.
"When the officer approached him, told him to stop, pointed a gun at him, he turned around and growled like a wild animal and kept eating at the man's face," Aguilar was quoted as saying by WPLG.
Augilar said he suspects that the attacker was under the influence of "bath salts," a drug that contains synthetic stimulants that can "cause chest pains, increased blood pressure, increased heart rate, agitation, hallucinations, extreme paranoia, and delusions," according to the National Institute of Drug Abuse.
