He objective of this research is to establish the relationship that exists between the fingerprint formulas and the persons accused in homicides of the Peruvian population carried out in the Criminalistics Directorate of the National Police of Peru between the years 2013 to 2017. The type of study is Descriptive, longitudinal, retrospective, nonexperimental design (correlational) and approach quantitative. The population is of Peruvians composed of 2690 persons incriminated in homicides, regardless of their economic situation or if they are primary or recidivist, with a sample constituted by 626 people, of which 565 are men and 61 women. The documentary review technique was used through dactyloscopic (Alphabetic) tabs from which the first variable was obtained, such as dactyloscopic formulas, while for the second variable the types of homicides (qualified, guilty and simple), including the homicide and its attempt were obtained in both sexes and thus from their analysis together obtain a possible formula by sex that demonstrates a possible common pattern of all of them. Among the results we found that if there is a statistically significant relationship of 47% between the fingerprint formulas and the types of homicide of the people incriminated in homicides of the Peruvian population. For the statistical analysis, Pearson's Chi2 was used, completing said relationship in percentage of the summary table of contingency coefficients, with a significant value in both index fingers in men being the higher valued in law with 53.5%; and in women, a significant value was also found in both middle fingers, with a higher value in the left with 81.2%. Finally, a coincidence was found in the finger type and subtype (4 / i) on the ring finger of the left hand with 17% in both men and women incriminated in homicides, which could indicate the existence of a possible pattern common finger.
