 The canonical five murders were perpetrated at night , on or close to a weekend , either at the end of a month or a week ( or so ) after . The mutilations became increasingly severe as the series of murders proceeded , except for that of Stride , whose attacker may have been interrupted . Nichols was not missing any organs ; Chapman 's uterus was taken ; Eddowes had her uterus and a kidney removed and her face mutilated ; and Kelly 's body was eviscerated and her face hacked away , though only her heart was missing from the crime scene .
