Jack The Ripper - Investigation

Investigation

The surviving police files on the Whitechapel murders allow a detailed view of investigative procedure in the Victorian era. A large team of policemen conducted house-to-house inquiries throughout Whitechapel. Forensic material was collected and examined. Suspects were identified, traced and either examined more closely or eliminated from the inquiry. Police work follows the same pattern today. Over 2000 people were interviewed, "upwards of 300" people were investigated, and 80 people were detained.

The investigation was initially conducted by the Metropolitan Police Whitechapel (H) Division Criminal Investigation Department (CID) headed by Detective Inspector Edmund Reid. After the murder of Nichols, Detective Inspectors Frederick Abberline, Henry Moore, and Walter Andrews were sent from Central Office at Scotland Yard to assist. After the Eddowes murder, which occurred within the City of London, the City Police under Detective Inspector James McWilliam were involved. However, overall direction of the murder enquiries was hampered by the fact that the newly appointed head of the CID, Robert Anderson, was on leave in Switzerland between 7 September and 6 October, during the time Chapman, Stride and Eddowes were killed. This prompted the Metropolitan Police Commissioner, Sir Charles Warren, to appoint Chief Inspector Donald Swanson to coordinate the enquiry from Scotland Yard.

Partly because of dissatisfaction with the police effort, a group of volunteer citizens in London's East End called the Whitechapel Vigilance Committee patrolled the streets looking for suspicious characters, petitioned the government to raise a reward for information about the killer, and hired private detectives to question witnesses independently.

Butchers, slaughterers, surgeons and physicians were suspected because of the manner of the mutilations. A surviving note from Major Henry Smith, Acting Commissioner of the City Police, indicates that the alibis of local butchers and slaughterers were investigated, with the result that they were eliminated from the inquiry. A report from Inspector Donald Swanson to the Home Office confirms that 76 butchers and slaughterers were visited, and that the inquiry encompassed all their employees for the previous six months. Some contemporary figures, including Queen Victoria, thought the pattern of the murders indicated that the culprit was a butcher or cattle drover on one of the cattle boats that plied between London and mainland Europe. Whitechapel was close to the London Docks, and usually such boats docked on Thursday or Friday and departed on Saturday or Sunday. The cattle boats were examined but the dates of the murders did not coincide with a single boat's movements and the transfer of a crewman between boats was also ruled out.
