A bizarre incident in Miami over the Memorial Day weekend leaves some wondering whether zombies could in fact be real. A man was shot and killed by police Sunday after eating the face of another man while naked.
The attack was a scene out of a horror movie. Identified as Rudy Eugene, the man growled at a police officer and continued to chew on his victim's face after being ordered to stop. Police are baffled by what could have caused this attack, but a potent form of LSD could be the culprit.
According to Miami television station WSVN, Eugene had likely overdosed on a new form of the hallucinogenic drug.
What's happening is whenever we see that a person has taken all his clothes off and has become violent, it's indicative of this excited delirium that's caused by overdose of drugs, Armando Aguilar of the Miami Fraternal Order of Police told WSVN.
The disorder is known as excited delirium, and is a drug-related condition that can incite violence, unexpected strength and hyperthermia.

Inside their body their organs are burning up alive, Aguilar said to NBC Miami. They've reached a temperature where their actually burning up, and it actually makes them take off their clothes.
According to ExcitedDelirium.org, the disorder has garnered attention over the past decade due to the sudden and seemingly inexplicable deaths of highly agitated subjects held in police custody.
In most of these cases, the force required to restrain or incapacitate the suspect was not sufficient to cause death, the website reads. Excited delirium was initially associated with cocaine abuse, and symptoms include bizarre and aggressive behavior, shouting, paranoia, panic, violence toward others and unexpected physical strength.
The disorder occurs when neurochemical systems in the brain are abnormal, characterized by dopamine transporters that get deregulated.
In the Miami-Dade County alone, there have been four recent cases of what is thought to be excited delirium, reported NBC Miami. However, none have been as severe and violent as Eugene's. In April, 21-year-old Geroge Salgado suffered similar symptoms. Police said they had to use a stun-gun on Salgado due to his aggressive behavior.
There's a naked man, and he's aggressive, a 911 caller said of the attack, according to NBC Miami. He tore my clothes and tried to bite my neck.
Salgado had taken three stamps of LSD, according to police reports.
An emergency room doctor also speculated that bath salts could have caused the abnormal attack. Bath salts are a drug with amphetamine-like chemicals, according to MSNBC. The drug also causes body temperatures to spike, and cases were reported at this year's Ultra Music Festival.
People don't drink water while they're taking it so they become dehydrated, Paul Adams, an ER doctor at Jackson Memorial Hospital said to NBC Miami. So you mix dehydration with elevated temperature with loss of inhibitions, and you have a life-threatening combination. Mix for disaster.
Bath salts were banned in Florida in 2011, reported NBC Miami, but new formulas have become popular since then.
We've had several deaths, Adams continued. Earlier last year we probably saw our first deaths from bath salts, where people (were) running onto MacArthur Causeway, under MacArthur Causeway, being chased by the police and then all of a sudden just collapsing.
The MacArthur Causeway to Miami Beach was the scene of Sunday's incident.
