We can't put a Modern Eye Toward an Old Investigation. The Police back them were not complete idiots. The problem with this case is that investigators weren't familiar with murders with no aparent reasons. Is not the same catching a murdering husband because of infidelity and so on.
Back then, there was no fingerprinting, footprinting or DNA analisys. The only thing they had was the work of a beat policeman.
He didn't. Jack the Ripper was never caught.
Jack the ripper was the first serial killer to reach the media. The world has eyes on him. It was a scandal about the condition the police was at that time. There were no false starts in this case. There was nothing to go on but the remains of the victims. Even today it takes quite some time to catch a murderer on the run, but in the case of Jack the Ripper, there were many aspects police today would not come across.
Scotland Yard never claimed to have captured Jack The Ripper and in fact were ridculed for their inablity to catch him. It resulted in many conspiracy theories, some involving the royal family, the police force and even Inspector Fredrick Abberline.
Unfortunately, not all killers are caught, even with today's advanced technology. To catch a killer like JTR the police would need some of that technology but it was not available for almost a century. They used the tools that were available but it was not enough to stop this particular killer.
He killed and ripped woman's bodies. The police received a boasting letter from a man claiming to be the killer. It was signed Jack The Ripper.
The London police never held the opinion that Jack the Ripper was murdered... he just stopped killing for reasons known only to him.
The killer refered to himself by several different names, Jack The Ripper and Saucy Jack are just a couple. He obviously had a flare for the dramatic. Jack The Ripper has become almost legend thanks in part to that 'oh so appropriated' name.
Frederick George Abberline - Chief Inspector for the London Metropolitan Police.
Thomas Cutbush was named as the Ripper by the Sun newspaper on the 13th February 1894. The possibility of Thomas Cutbush being Jack the Ripper was thoroughly investigated by the police at the time, and shown to be without foundation.
police was not as affective as they are now and there was no way of finding pepoles DNA
Jack The Ripper was not caught because police did not possess the tools needed to catch this kind of killer. No way to analyze blood and fibers. No crime scene preservation. No criminal profiling. No computers, ect. These are how modern serial killers are caught.because they had insufficient devices as we do now, after all it was nearly 100 years ago!!!
The real identity of Jack the Ripper is not known. In a time before forensic science and even finger printing, the only way to prove someone committed a murder was to catch either him or her in the act, or get the suspect to confess. There was no scientists working with police to gather crime scenes evidence to help capture the victimarius.
