For reasons that are not entirely clear, with the death of Mary Jane Kelly on November 9, 1888, the publicity surrounding the Ripper case more or less fizzled out, giving a false sense of security in London. The popular idea that Mary Ann Nichols was the first victim on August 31, 1888, or that Kelly was the last on November 9 is almost certainly not correct. So it's easier to keep track of the Ripper's crimes in years, not weeks.
More than likely Martha Tabram, found murdered on Aug. 7, was a Ripper victim. There are possibly 2 or 3 before Tabram that may or may not be linked to JTR. It is also more than likely that the murders continued until 1891 and beyond. In 1907 a prostitute was found murdered, throat cut, in Camden Town, a neighborhood on the perimiter of Whitechapel.

Everybody seems to have their own favorite suspect as Jack the Ripper. There has never been a shortage of suspects or opinions on the identity of this notorious killer. I have studied the crimes of the Ripper and read many books on this subject including modern investigations using 21st century investigative tools and my opinion is that Walter Sickert was the Ripper. There is DNA evidence that links letters of Sickert's to some of the Ripper letters. This is but one example of the many "coincidences" that ties Sickert to the Ripper crimes.
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.
He didn't. Jack The Ripper's crimes continued long after the murder of Mary Jane Kelly on November 9, 1888. Many believe the Ripper was still killing as late as 1891, and possibly after the turn of the 20th century.
Find a good, detailed review of Discovery Channel's "Jack the Ripper in America" at The 44 Diaries blog. It gives you a complete summary of the documentary, and includes many links and photos. Including the new composite of what detectives think Jack the Ripper really looked like.
Like many other Ripper suspects, Thompson was associated with Jack The Ripper only by the flimiest of circumstances. Thompson had trained as a medical doctor and he lived just south of Whitechapel. Other than that I could find no other reason for him to be a suspect.
