The copy of Anderson's memoirs containing the handwritten notes by Swanson was donated by his descendants to Scotland Yard's Crime Museum in 2006. In 1987, Ripper author Martin Fido searched asylum records for any inmates called Kosminski, and found only one: Aaron Kosminski. At the time of the murders, Aaron apparently lived either on Providence Street or Greenfield Street, both of which addresses are close to the sites of the murders. The addresses given in the asylum records are in Mile End Old Town, just on the edge of Whitechapel. The description of Aaron Kosminski's symptoms in the case notes indicates that he had paranoid schizophrenia. Macnaghten's notes say that "Kosminski" indulged in "solitary vices", and in his memoirs Anderson wrote of his suspect's "unmentionable vices", both of which may match the claim in the case notes that Aaron Kosminski committed "self-abuse". Swanson's notes match the known details of Aaron Kosminski's life in that he reported that the suspect went to the workhouse and then to Colney Hatch, but the last detail about his early death does not match Aaron Kosminski, who lived until 1919 (see below). Anderson claimed that the Ripper had been identified by the "only person who had ever had a good view of the murderer", but that no prosecution was possible because both the witness and the culprit were Jews and Jews were not willing to offer testimony against fellow Jews. Swanson's notes state that "Kosminski" was identified at "the Seaside Home", which was the Police Convalescent Home in Hove near Brighton. Some authors express scepticism that this identification ever happened, while others use it as evidence for their theories. For example, Donald Rumbelow thought the story unlikely, but fellow Ripper authors Martin Fido and Paul Begg thought there was another witness, perhaps Israel Schwartz, Joseph Lawende, or a policeman. In his memorandum, however, Macnaghten stated that "no-one ever saw the Whitechapel murderer", which directly contradicts Anderson's and Swanson's recollection. Sir Henry Smith, Acting Commissioner of the City of London Police at the time of the murders, scathingly dismissed Anderson's claim that Jews would not testify against one another in his own memoirs written later in the same year, calling it a "reckless accusation" against Jews. Edmund Reid, the initial inspector in charge of the investigation, also challenged Anderson's opinion. There is no record of Aaron Kosminski in any surviving official police documents except Macnaghten's memo.
