(Universidad Privada Norbert Wiener, 2020-09-30) Pinto Gamarra, Richard Manuel; Quiroz Mejía, Jesús Miguel
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.

The objective of this study was to establish the effectiveness of human identification through an imaging study of the auricular pavilion, in a sample of users of the Legal Medical Division of Chachapoyas - 2019. This study of observational, descriptive and comparative methodology, analyzed 45 atrial pavilions corresponding to the users, women and men, of the different services provided by the Chachapoyas Legal Medical Division. In order to demonstrate the effectiveness of the study of the auricular pavilion as an identification method, it was carried out by means of the analysis of the Aiken coefficient, assuming a level of statistical significance considered as valid. The results showed that the human identification by study of images of the region of the helix, antihelix, shell and lobe, is effective due to the concordance with its morphology, dimensions and individualizing characters, assuming a level of statistical significance for the case of the Helix of p = 0.001, considered valid; in the case of the antihelix of p = 0.001, considered as valid; in the case of the shell of p = 0.001, considered as valid, and in the case of the lobe of p = 0.049, considered as valid. Likewise, a probability was established that an atrial pavilion is repeated with the same height and width measurements is 0.0222, indicating that the event can occur remotely. Concluding that the human identification by study of images of the auricular pavilion is effective for the concordance with its morphology, dimensions and individualizing characters of the regions of the helix, antihelix and atrial shell, in a sample of users of the Legal Medical Division of Chachapoyas.

An investigation was carried out using the prostate specific antigen (PSA) and acid phosphatase (FA) test, with the aim of determining its effectiveness in relation to the detection of seminal fluid in clothing, also the search for sperm was performed by microscopic observation (MC) as a confirmatory test for the detection of this type of fluid; 129 clothing items such as tricks, pants and shorts, belonging to women victims of rape were analyzed according to legal medical examination. The reliable presence of seminal fluid was detected in 90 garments (70%) checked by the positive results to the MC; seminal components such as: PSA in 94 garments (73%), FA in 88 garments (65%); in 39 samples (30%) the presence of seminal fluid was not detected; the integral analysis of the data obtained revealed 4 types of associations of results with variations of positivity and negativity of the tests, being 82 (64%) the I (PSA +, FA +, MC +), 2 (1.5%) the II (PSA +, FA -, MC -), 8 (6%) the III (PSA +, FA -, MC +) and 2 (1.5%) the IV (PSA +, FA+, MC -). The statistical analysis applied to the results reflected a well-marked positive correlation in relation to the results obtained by the PSA and MC association with a statistical value p0.05 and a Spearman correlation index (rho) of 0.9270 closer to 1, in comparison to the one obtained by the FA and MC test that showed a value (rho) of 0.8286, statistically determining a greater association and interdependence relationship between the results of the PSA and MC tests; 100% efficacy was also determined in terms of the detection of seminal fluid in garments by using the PSA test in relation to 91% effectiveness of the FA test, corroborated by the positive microscopy results.

The main objective of this research is to determine the relationship between contaminating factors and biological evidence at the crime scene, according to Experts from the Chiclayo Criminal Investigation Division, 2019. This study is of a hypothetical-deductive method, quantitative approach, Basic type, observational descriptive correlational, non-experimental, cross-sectional design. The sample is 30 experts from DIVINCRI. The survey was used as a technique and as an instrument, two questionnaires prepared by the researcher. The reliability of the instruments for the independent variable yielded a Cronbach's alpha coefficient of 0.817 and for the dependent variable 0.794, which determines that the instruments are reliable. According to the hypothesis test, the Spearman correlation coefficient indicates a statistically significant, moderate and inversely proportional linear relationship between both variables (rho = - 0.527 (p <0.05)), so the higher the level of contaminating factors, the less evidence Biologicals at the crime scene. Among the results obtained, 47.1% of the experts who indicate a high level of human contaminating factors indicate a low level of biological evidence; likewise, 44.4% of experts who indicate a high level of environmental contaminating factors indicate a low level of biological evidence; On the other hand, 47.6% of experts who indicate a high level of contaminating factors indicate a low level of biological evidence. It is recommended to carry out training for DIVINCRI personnel, as a prevention strategy for contamination at the crime scene.

(Universidad Privada Norbert Wiener, 2019-08-24) Francia Flores, Feliciano; Quiroz Mejía, Jesús Miguel
The objective of this study was to identify the influence of the academic training of the experts in the criminal investigation of the crime scene in cases of parricide, Cercado de Lima, 2016-2017. This study of observational, cross-sectional, relational, retrospective and correlational methodology, analyzed 11 criminalistics experts who participated in the cases of parricide that occurred in the district of Cercado de Lima, selected based on the inclusion and exclusion criteria established for the study. To determine the influence of academic training, we chose the Mann-Whitney U, whose pvalue was less than 0.05, demonstrating significant influence. The results showed that the academic training of the experts was based on a bachelor's degree (81.8%), having received 5 or more trainings (63.6%) and experience in criminalistics greater than or equal to five years (63.6%). The academic degree of the experts does not influence the criminal investigation of the crime scene of the cases of parricide (p = 0.194). In contrast, training (p = 0.004) and experience time (p = 0.004) significantly influence criminal investigation of the crime scene. Concluding that the academic training, referred to the training and experience time of the experts, influences the criminal investigation of the crime scene in cases of parricide.
