It’s hard to imagine people being able to murder multiple times without leaving evidence that leads to their arrest. Especially in our current day and age where there’s cameras and gps everywhere, not to mention forensic evidence being able to pull your entire DNA out of a single strand of hair. Those weren’t always the times we lived in, and some serial killers were never caught due to this.
Here’s a few serial killers throughout history that we never quite managed to catch for some reason. Don’t worry, none of them are active anymore, so you can rest easy.
The Alphabet Killer
Back in 2011 there was a small bit of hope that the Rochester-based Alphabet Killer had finally been caught, but sadly the DNA of the then-convicted killer didn’t match the DNA found on the Alphabet Killer’s victims. The Alphabet Killer only picked victims whose first and last name started with the same letter. He made three victims in the early 1970s, raping and strangling each one.

The Zodiac Killer
This killer is mostly known for his cryptic ciphers and taunting the police every step of the way. He pretty much scared everyone back in the 1960s because despite only five murders being connected to Zodiac, he claimed to have killed 37. He released four ciphers and over 50 years later, only two have been cracked. One of them allegedly contains the identity of the killer so maybe one day we’ll find out who the infamous Zodiac killer was.

The Long Island Killer
There’s about a dozen, and maybe even more, murders that can be attributed to this killer and his most recent victim was only found little over a decade ago. This leads the police to conclude that he’s very much aware of law enforcement techniques, because otherwise there’s no way someone could make this many victims and possibly still remain at large.
