Most believe that the first victim was Mary Ann "Polly" Nichols, though some believe Martha Tabram or Annie Millwood was the first.
Mary Ann Nichols was killed on 31 August 1888. This is the first wowan in the rippers case.
It is very probable that his first victim was in London.
If you mean Jack The Ripper it is impossible to tell due to the fact that there are differing opinions on who his first victim was.
On Friday, 7th September 1888, Annie Chapman became the second victim of Jack the Ripper. The estimated time was 4.30 am or before.
Elizabeth Stride is assumed to be the third victim of Jack the Ripper. She was murdered.
The first "canonical" victim was Mary Ann (also known as "Polly") Nicholls, who was killed on 31 August 1888, but it is now fairly widely accepted by commentators and theorists that Martha Tabram, who was killed on 7 August 1888, was most likely an earlier Ripper victim. There are also a number of non-fatal attacks on women earlier in 1888 which potentially fit the Ripper's modus operandii.
The second Victim of Jack the Ripper is generally accepted as Martha Tabram, killed 6 August 1888.Martha Tabram was most likely the 2nd victim of Jack The Ripper. It is widely accepted that his first victim was Annie Millwood, whom was attacked by a man she didn't know in February of 1888. She survived the attack but died a month later of an aneurysm. Tabram was several weeks before Polly Nicholls. Most experts agree that Mary Anne Nicholls was the third victim of the Whitechapel Murderer.
7th September 1888, Annie Chapman became the second victim of Jack the Ripper.
He did on at least one victim. The mutilations got more extreme with each killing.
The first victim was most likely Martha Tabram, killed on August 7, 1888, weeks before Mary Ann Nichols.
As far as anyone can tell, Jack The Ripper cut the throats of all of his victims first, before disembowling and mutililating them. This is what is called his MO or modis operandi, how he killed his victims. There is a very logical reason why the Ripper cut his victim's throats first. It left them unable to scream and call attention to the killer. It worked very well. For the most part, JTR worked in relative quiet.
For many years it was believed the Mary Kelly's murder on November 9, 1888, was Jack The Ripper's last murder. This simply is not true. A prostitute named Francis Coles was murdered in Whitechapel in 1891 who is now also thought to be killed by JTR. It is also most likely that Mary Ann 'Polly' Nichols was not the Ripper's first victim. At the very least Martha Tabram, who was found murdered several weeks before Nichols, was the Ripper's also. If this is true than Kelly would have been the Ripper's sixth victim, not the fifth.
The Ripper's only purpose was to please himself. His crimes were all about him and his power over his victim's lives and deaths. To the rest of the world, his crimes made no sense at all.
