Our list of unsolved murders continues with these notorious crimes.
6. Tupac Shakur
On September 7, 1996, successful rap artist Tupac Shakur was shot four times in a drive-by shooting in Las Vegas. He died six days later. Two years prior to that, Shakur had been shot five times in the lobby of a Manhattan recording studio the day before he was found guilty of sexual assault. He survived that attack, only to spend the next 11 months in jail. The 1994 shooting was a major catalyst for an East Coast-West Coast feud that would envelop the hip-hop industry and culminate in the deaths of both Shakur and Notorious B.I.G. (Christopher Wallace).
On the night of the fatal shooting, Shakur attended the Mike Tyson-Bruce Seldon fight at the MGM Grand in Las Vegas. After the fight, Shakur and his entourage got into a scuffle with a gang member. Shakur then headed for a nightclub, but he never made it. No one was ever arrested for the killing.
7. Jack the Ripper
In London in the late 1880s, a brutal killer known as Jack the Ripper preyed on local prostitutes. His first victim was 43-year-old Mary Ann Nichols, who was nearly decapitated during a savage knife attack. Days later, 47-year-old Annie Chapman had her organs removed from her abdomen before being left for dead.
The press stirred up a wave of panic reporting that a serial killer was at large. Three weeks later, the killer was interrupted as he tore apart Swedish prostitute Elizabeth Stride. He managed to get away, only to strike again later that same night. This time the victim was Kate Eddowes. The killer, by now dubbed Jack the Ripper, removed a kidney in the process of hacking up Eddowes's body. His final kill was the most gruesome. On the night of November 9, 1888, Mary Kelly was methodically cut into pieces in an onslaught that must have lasted for several hours.
Dozens of potential Jacks have been implicated in the killings, including failed lawyer Montague John Druitt, whose body was fished out of the Thames River days after the last murder was committed. The nature of the bodily dissections has led many to conclude that Jack was a skilled physician with an advanced knowledge of anatomy. But more than a century after the savage attacks, the identity of Jack the Ripper remains a mystery.
