A naked man with "superhuman strength" was shot to death Tuesday night after assaulting a former police officer and biting part of a teenager's face off.

According to Palm Beach County Sheriff Ric Bradshaw, the naked man was walking down a road near Delray Beach, Florida when, for reasons that remain unclear, he attacked a 66-year-old former NYPD officer. The retired cop was rushed to the hospital with serious injuries.

Meanwhile, the naked man continued up the road, where he encountered and chased a man walking with his 10-year-old son. Later, the naked man attacked an 18-year-old man, biting his face until the teen stabbed the man with a box cutter or knife. By that time, police officers had arrived on the scene and attempted to Taser the nude man.

"He's obviously delirious on something," Palm Beach County Sheriff Ric Bradshaw told the Palm Beach Post. "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."

A deputy then shot the man three times, once in the torso and twice in the lower body. The man died later that night at a nearby hospital.

"We don't know right now if he's expired from the gunshots, or if he's expired because of obviously he's on some type of drugs that have made him act like this," Bradshaw said. "There's no way to know if those are the shots that actually killed him, or if he's died from what they called exited delirium. He's obviously on some type of narcotics to make him act like this."

UPDATE: Here's video of police shooting the suspect.
