Authorities shot and killed a Florida man after he allegedly bit a teenagers face and attacked an ex-police officer.

Palm Beach County Sheriff Ric Bradshaw told reporters that witnesses described the 6'3", 250 pound man as having "super human strength," according to the Palm Beach Post.

Bradshaw said the man, who has not been identified, was walking naked down a Delray Beach street on Tuesday night when he, for no apparent reason, attacked a 66-year-old former cop.

Then the suspect allegedly assaulted an 18-year-old man, biting off a portion of his face, Bradshaw said.

Once police arrived, they were allegedly unable to subdue him until an officer shot him down.

"He’s obviously delirious on something,” Bradshaw said. “He is a huge guy. He takes a fighting stance. They’re trying to get him on the ground. He starts charging them. The Taser did not affect him.”

That's when an officer pulled his gun and shot the man three times. He died in a hospital either from his injuries or from the "narcotic" substance he was on, Bradshaw said.

The case comes nearly one year after another Florida case stoked fears of a zombie apocalypse.

In May, 2012, Rudy Eugene, 31, of North Miami Beach was shot multiple times during a grisly assault in which he apparently chewed a man's face almost completely off.
