In my opinion, there were several major flaws with the police investigation. One such flaw was the refusal to allow blood hounds to be used. I believe blood hounds were used there could have been more success with finding a suspect. I also believe that the police were not very thorough with cataloging the items found in each crime scene. There may have been a possibility that the murderer left behind evidence, which could have been found if proper cataloging were implemented. I also found it odd that the police waited several hours to investigate the crime scene of Mary Jane Kelly. Valuable evidence was lost with each passing minute, yet the police refused to enter the room. I understand that forensic pathology was not yet available, but there must have been other means of analysing evidence at that time. It also seems quite peculiar that the murders stopped during the time that James Kelly was at Broadmoor. I believe if the police had realized that the reason the murders stopped was that the murder was detained, either in jail or an asylum, it could have led to his capture. The police could have looked at jail and asylum records to see who was serving time during the months that the murders stopped. Simple steps could have been taken to find a possible suspect, such as James Kelly. I believe there were several flaws in the police investigation, but the lack of thorough fact finding was a major mistake made by the British police of the day.
