Fido, p. 37 John Pizer, a 38-year-old Polish Jew who made footwear from leather, was known by the name "Leather Apron". Via knifepoint, Pizer frequently intimidated local prostitutes. He appeared before the Thames Magistrates' Court on 4 August 1888, charged with indecent assault. Pizer is also believed to have stabbed a man in the hand in 1887. Despite there being no direct evidence against Pizer, he was arrested by a Sergeant William Thicke on 10 September. Although Pizer claimed to the contrary, Thicke knew of Pizer's local reputation, and his "Leather Apron" nick-name. Pizer was released from custody on 11 September after police were able to verify his alibis on the nights of the murders of both Chapman and Nichols. He was called as a witness on the second day of the inquest into Chapman's murder to publicly clear his name, and demolish the public suspicions that he was the killer. Pizer also successfully obtained monetary compensation from at least one newspaper that had published several articles naming him as the prime suspect in the Whitechapel murders. Pawnbrokers Two brass rings—one flat; one oval—Chapman is known to have worn were not recovered at the crime scene, either because she had pawned them or because they had been stolen, possibly by her murderer.

Stanley was soon eliminated as a suspect as his alibis for the nights of the murders of both Nichols and Chapman were quickly confirmed. Between 6 August and 1 September, he was known to have been on active duty with the Hampshire Militia in Gosport, and on the night of Chapman's murder, eyewitnesses confirmed Stanley had been at his lodgings. Further enquiries and arrests In addition to John Pizer and Edward Stanley, police investigated and/or detained several other individuals in their investigation into Chapman's murder, all of whom were released from custody. On 9 September, a 53-year-old ship's cook named William Henry Piggott was detained after arriving at a Gravesend pub with a recent hand injury and shouting misogynistic
