Humans have this never-ending fascination for stuff they don't really understand, especially when situations or topics are loathsome. It's their favorite genre! Historical murder mysteries thus rank at the top of such situations.

Such mysteries usually remain unsolved because of lack of evidence, misplacement of excavated material, or destruction of a crime scene. Maybe that's why investigators end up circling around them every now and then, knowing that the real answers will never be discovered. All that everyone does is use their imagination to circle out a possible explanation, just so they can sleep peacefully.
Although hundreds and thousands of historical cases haven't received the desired justice, here are some that'll force you to scratch your heads.
Who was Jack the Ripper?
In 1888, a serial killer, infamously known as Jack the ripper, murdered five ladies in the streets of London and disfigured their bodies. When police officials failed to catch him, he sent them a number of letters to mock them for their failure. Now, although the police received such letters, whether or not any of them were actually handwritten by the ripper, is a mystery to date!

Gratuitously enough, the ripper was never found, and over the decades, there have been dozens of people who’ve been suspected by the police officials, but nothing has been proven so far. The mystery seemed to have hit a cold trail since the past few years, but recently, a book was discovered which claimed that a woman named Lizzie Williams was the actual ripper committing the gruesome murders. But many investigators called it out as a false claim, and as such, it seems like the truth behind the real identity of the ripper will always remain a mystery.
Who killed JFK?
This is probably one of the biggest mysteries that has existed in American history. It wasn't solved then, and it will probably never be solved. On 22 November 1963, the President of America, John F. Kennedy, was shot to death in front of live spectators as his car troupe passed through the streets. According to reports, the shooter was Lee Harvey Oswald, but there have been some speculations that he wasn't the only one behind the shooting. What prompted such doubts was the fact that not long after Kennedy's assassination, on November 24, 1963, Oswald was shot by a nightclub owner named Jack Ruby. This was right before Oswald was about to stand for his trial.

Keeping the facts and findings in perspective, a number of professional historians refuse to believe most of the widely accepted explanations behind JFK's death. In fact, there have been various alternative explanations that have been bought under the radar. Yet, in all probability, a firm concord will never be achieved.
To sum it up
There is an old saying, time heals everything and it's best to move on with it. A lot of mysterious cases remain unsolved because people and officials have moved on. They think it's a waste of time to dig so deep into the past. Yet, history is a testament to the fact that there are a number of crimes that get resolved several years after happening. So we shouldn’t give up hope. Yes, miracles do happen!
