A murder detective is supposed to find a way of performing where lethal muzzle attacks are likely to occur.
The Ch Insp John Massey disappeared due to recordings of knee populations in London over a 12-month period and found a link with fatalized stampings the following year.
More than two-thirds of one-to-one killings in 2017-18 appeared in weeks when the year before one was hit with a cut.
The study is believed to be one of the first to see such clear correlation.
Research, next to Cambridge criminologists' universities, found that in 2016-17 the Metropolitan Police 3506 were involved with a cut where the location of the attack was "" received.
The stabbings took place in 2,048 of the 4,835 local census of London – weeks with a population of approximately 1,700, which are smaller than council meetings.
The areas of the sites were then compared to the known locations of 97 fatality attacks in 2017-18.
Results were found to be 67 of murders – 69% – of which at least one of & # 39; last year was.
Mr Massey said: "These findings indicate that civil servants are being deployed in a smaller number of areas in the knowledge that they are getting the best chance of preventing them."
In one area, around Tanfield Avenue in Neasden, there were eight maternal deaths in the 12 months to March 2017 – followed by the fatal stabbing in October of that year by 18-year-old Saif Abdul Magid.
Two boys, 14 years old, were found guilty of his murder, where the police said it was the result of a summer ring.
Prof. dr. Lawrence Sherman, who's collaborating with the study, though only on the strengths of hotspots, wasn't a "panacea" to hit many murders in areas not complaining of stabbing directing by means of sinks.
"If suspicious data predicts that a neighborhood more than likely experiences the knee-homicide, police commanders can find everything from closer control of school exclusions to local use of stop-and-search," he said.
Mar. Sherman urged forces to improve their data collection processes to distinguish between arresting and trespassing arrests.
"The current definition of crime in crime is too broad to be useful," he said.
"Police IT is in urgent need – rather than just keeping legal records for legal use, the systems must be developed to provide crime pillars for priority purposes.
"We need to postpone IT from electronic conversations in future performance achievements," he said.
The study, published in the Cambridge Journal or Evidence-based police, also found 21% of & # 39; A 590 fatal stabbings in London over a 10-year period brought by the police in high heights.
The researchers say the figures "attempt to make a broadly visible view that metrics are primarily gangways", although in 2017-18 the range was 29%.

As a response, Cdr David Musker said the Met was "always open to traveling and using emerging academic research" and supporting its own current research.
He added: "All research that can help & # 39; help inform if the short and long-term response to violence is very welcome.
"We are already doing highly visible patterns in high-demand regions and hotspots and proactively policing risk killers and well-known criminals as part of our daily police plans; we also use predatory analytics and directories to preserve our patrols and use our best source, prioritize the greatest areas of threat, risk and damage.
"This is what the Met, and colleague's about the country, developed and use for a number of years a tremendous effect."
& # 39; Shift in mindset & # 39;
Home Secretary Sajid Javid is planning his writing on crimes in a Monday Monday discussion.
Mr Javid is expected to "claim" the "mentality" of the government to fight the problem – and argue for the use of data to help us understand the pathways and causes of crime .
Eliminating its support for a "public health" approach, the Secretary of State will also say that violent offenses should be treated as the "outbreak of some virulent disease".
