  • Police Patrols Timings

    Hi all
    Is it fair to suggest that the killer must have had knowledge of the timings of the police on the beat ? Either that or he got incredibly lucky on a couple of occasions at least. Assuming the former for now, doesn't that suggest a very local man who was used to being in the area at night ? He must have had good night vision too based upon the killings in the dark, which also alludes to the previous question. Would this help narrow down the suspect pool somewhat ?

    Cheers

    Hello Dick.

    What is believed by most is that the victims, being prostitutes, would have a better knowledge of any constable's beat on their patch. The prostitute will choose to take their customer to a dark corner just after the beat constable had left, giving them maximum time for the 'transaction'. Jack did not need to know the beat times.

    I'm not so sure about needing extra ordinary sight at night, most of what the killer did was possible by touch alone, but we shouldn't believe he operated in total darkness either. Even in Mitre Sq, his darkest location, the corner was not totally dark.

      Hi Jon
      Good point about the ladies knowing the beat times but Jack didn't magically appear at those moments unless he knew them too as there's no suggestion of him hanging around in advance, or is there ?

      Again just based on instinct, yes you may strangle and slit a throat by feel in the dark, but removing organs ? That goes beyond having normal capabilities, surely.

          You are spot on, there has been all this talk previous about butchers or slaughterers being able to remove these organs using anatomical knowledge. If that be the case we would have them helping out the NHS with the current pandemic backload.

            But to find and remove the organs by touch alone would need a great deal of anatomical knowledge in first being able to locate them, and then to be able to take hold of them, and then remove them as has been described in such a short time frame.

              No, his victims led him to where they felt the most comfortable, they knew the area better than him (or any customer).
              Prostitutes didn't need light to carry out their function.

              Removing organs is done mostly by feel anyway, I'm talking about the emergency room. The abdomen is full of either organs or blood, a doctor needs to know where to feel and what each organ feels like.

                Organs are removed with the knife, they are found by touch. An abdomen is not empty like those anatomical models.

                  Hi Dickere,

                  If JtR were local, which there are good arguments made to suggest that, it would be unsurprising if he was aware of some basic aspects concerning police beats. Most beats were set to require about 15 minutes to complete, some were a bit shorter (PC Watkin's, for example, had a beat that required him between 12 and 14 minutes to complete), and others were longer (PC Neil, from Polly Nichols' case, had a beat that required about 30 minutes to complete). The direction (i.e. clockwise vs counterclockwise) was changed every so often, and beats were occasionally "redrawn", as the police did not want criminals scouting some building to get too familiar with things. So, it's unlikely that JtR would have specific knowledge of any of the beats associated with the crimes, but it would be expected he had a general idea of how long beats in general took to complete.

                  The victims would likewise know of locations to conduct trade where they were unlikely to be disturbed for the amount of time required to conduct business. For some of the crimes we have pretty good information about the beats some of the police covered, and can estimate their positions as they completed them. That allows us to identify time windows for when the victims could arrive at the crime scene without having been seen to do so by the patrolling officer. We can also work out estimates of when JtR would have had to leave the scene to avoid being spotted when the officer returns. While these sorts of reconstructions will, of course, not be perfect recreations of the actual events, they do provide information to work with. Some interesting things have emerged, such as the Church Passage Couple (associated with the Eddowes case), are last seen in a location that would have provided them the opportunity to have seen PC Watkin's as he patrolled Mitre Square on his round prior to his finding Eddowes. And while we do not know if the Church Passage Couple was indeed Eddowes and JtR, it is worth considering that those two people are in a location that would make it possible for them to have seen PC Watkins patrol the area, which coupled with the above general knowledge, would lead to them making the assumption the square will be unvisited for about 15 minutes. That turns out to have been incorrect, though, as PC Watkin's beat was a shorter one, and also PC Harvey would patrol Church Passage itself (though his beat doesn't enter Mitre Square, it did come right up to it). So, like I say, that sort of thing doesn't prove the CPC were Eddowes and JtR, but what it does is tell us that the CPC couple had the opportunity to enter the square as PC Watkin's left it, which maximizes the amount of time available for the crime. In the Eddowes case, that's important to know because the timing is so tight making it hard to understand how JtR could murder and mutilate within that time window. If he had all of the time available, then it becomes less difficult to understand - it's still not a lot of time, but it is enough.

                        But where did he appear from at that moment ? Presumably there wasn't a queue, so wouldn't he also have had knowledge of the beat times to be there at just the right moment ?

                          And to be able to remove them in almost total darkness that person would have to have expert knowledge in how to first find them and then have the expert knowledge to be able to remove them in the way described?

                            Given Mitre Square is described as the least lit murder location, and that Dr. S testifies there was still enough light for JtR to do what he did, it becomes irrelevant to wonder how many people could do it under different conditions ... Meaning describing it as "almost total darkness" describes a situation nobody has to explain because it does not accurately describe the events to be explained.

                              Hi Dickere,

                              Trevor has a theory that JtR didn't take organs from any of the crime scenes, but rather they were stolen from the different mortuaries. It's not a widely held belief, but one Trevor defends at every opportunity. You can find discussions on this in many threads.
