Sir Charles Warren was the commissioner of The Metropolitan Police.

Warren’s biggest difficulty was the Jack the Ripper case.

He was probably unfairly blamed for the failure to track down the killer and faced press accusations that were frequently baseless.

Warren had had enough and resigned…coincidentally right before the murder of Mary Jane Kelly on 9 November 1888.

Warren’s resignation hindered the investigation. He had given an order that if another murder occurred, nobody was to enter the scene – a strange turn of phrase as the four previous victims had all been found in the open street – until he arrived to direct the investigation.

Consequently, with the murder of Kelly the police did not enter the room for some three hours because, unaware of his resignation, they were waiting for Warren to arrive.
