An unidentified man savagely attacked by another on the pedestrian walkway of the MacArthur Causeway remained in intensive care on Sunday at Ryder Trauma Center in Miami.

The man, whose name has not been released, was said to have suffered severe facial injuries from an attacker who witnesses said chewed at the victim’s face and eyes in the walkway on the west end of the causeway. Both men were naked.

When police arrived, the attacker refused to stop biting the other man and was shot dead by a Miami police officer…

According to police sources, a road ranger had seen a naked man chewing on another man’s face and shouted on his loud speaker for him to back away. Meanwhile, a woman also saw the incident and flagged down a police officer who was in the area.

Video captured by the Herald security cameras show snippets of the man on the ground, then an officer arriving on the scene and the aftermath of the attack. The video does not show any of the violence…

The attacker failed to stop after being shot, forcing the officer to continue firing. Witnesses said they heard at least a half dozen shots…

Police theorize the attacker might have been suffering from “cocaine psychosis,” a drug-induced craze that bakes the body internally and often leads the affected to strip naked to try and cool off.

“Cool off” hardly seems adequate.
