The Most Dangerous Active Serial Killers In 2021

While there are quite a few science events happening in 2021 that may give us hope for a bright future, the world also faces a laundry list of problems that don't seem to be going away any time soon. For example, in addition to that pesky pandemic that still threatens our every move, you can't forget about the multiple serial killers that remain active and at large today. According to Serial Killer Shop, there are nine serial killers currently running free and potentially continuing their killing sprees as we head into 2021. If you're in New York, you might want to keep an eye out for the Long Island Serial Killer. His spree now spans two decades. The deaths of at least ten people have been attributed to him since 1996, and it's possible and likely that there are more.

Also called the Craigslist Ripper, his MO has been to hire sex workers on the online classifieds platform, luring them to a place where he can kill them. Authorities believe that he has used Long Island's Gilgo Beach as his dumping ground. While searching for a missing woman, they uncovered the remains of four victims, then found six more after broadening the search area. Eight of the ten victims were women, all of them sex workers who had publicized their services on Craigslist. One of the others was a toddler and the other was a male cross-dresser. One theory proposes that the killer has a background in law enforcement.

The Smiley Face Murders still go unsolved

It doesn't seem out of character for a frat boy to gulp down a few too many pills with a few too many shots, and then in the stupor, stumble into the nearest body of water and accidentally drown. Frat boys have definitely done stupider things. Neither does it seem too far-fetched for this to happen multiple times in several states across the country. It's a party — hey-oh! Sounds like an open and shut case, right?

Well, according to The Daily Beast, after this happened around 100 times in at least nine states, investigators started to get suspicious. And when they kept finding creepy smiley face graffiti near the places where the bodies were found, they started to put a theory together. Now the retired detectives of Global Death Investigations believe that there is actually a gang of serial killers who have organized on the deep web to commit these murders, and they suspect their involvement in as many as 250 other cases. It may seem like a stretch, but the facts all point to this being the case. For example, all of the victims fit a particular profile: white, male, athletic, popular, and successful. Many were drugged with the date rape drug GHB. Then there's the fact that some bodies didn't show the kind of deterioration expected after having spent several days in the water. As it stands today, the Smiley Face Killers are still at large.

Serial killers at large outside the U.S. in 2021

The United States isn't the only country with its share of serial killers. For example, in Brazil, investigators thought they had nabbed the Rainbow Maniac in 2011, but a jury found him not guilty, so the case is still unsolved. The deaths of 13 gay men in Carapicuiba, Brazil, in 2007 and 2008 were attributed to the Rainbow Maniac. They were all killed execution-style in a park and left in the bushes with their pants pulled down. Although the city is known as one of South America's most progressive, there were several reactionary conservative groups active at the time that were very outspoken against homosexuality, and it is believed that one of their members could have been responsible.

In Japan, the person responsible for poisoning dozens of people in 1985 has never been found. The killer tainted drinks from vending machines with a poison called paraquat. According to The New York Times, the Vending Machine Killer murdered at least 10 people, left around 35 more in serious condition, and likely inspired a number of copycats.

More recently, a motorcyclist in Nigeria entered a place called the Ibadan Forest of Horror, or the Evil Forest, and found a group of buildings containing more than 20 corpses and ten people still alive in chains. Per World Bulletin, arrests were made, but no one has ever been charged in the case. It was rumored that they were involved in cannibalism and ritualistic sacrifice.
