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 research design is non-experimental, applied, cross-sectional and descriptive. 141 forensic evidence from 36 criminalistics cases were analyzed where it was possible to determine that the genetic profiles met the criteria for general interpretation of mixed profiles, for which 98% exceeded the analytical threshold (≥ 50 RFU), 82% exceeded the threshold stochastic (≥ 150-200 RFU), 60% exceeded the stutter threshold (≥ 10-15% RFU), 92% presented heterozygote imbalance (< 0.6), the proportion of contributors 0.1-1 was distinguishable in 62 %, the extrabands recognizable in 60% were the stutters, the presence of genetic artifacts was in 44% and the stochastic, degraded and/or inhibited profiles are related to the types of mixture profiles. In the criminal cases of a single aggressor, they met the general thresholds of scientific recommendation, likewise the mixed profiles were interpretable, the conclusive cases were in 78 pieces of evidence and the inconclusive cases were in 13 pieces of evidence. In the criminal cases of multiple aggressors, the mixed profiles met the general thresholds of scientific recommendation, likewise these profiles were interpretable, the conclusive cases were 41 pieces of evidence and the inconclusive cases were 9 pieces of evidence.

(Universidad Privada Norbert Wiener, 2024-06-24) Manriquez Zapata, Héctor Miguel; Montellanos Cabrera, Henry Sam
The objective of the study was to evaluate the relationship of the Decision Tree method and the Non-Metric Sex Assessment proposed by Langley to determine the true sex using a contemporary digital sample from the Province of Chachapoyas, Amazonas Region - Peru 2023. A quantitative study, since morphological dimensions of the skull were used to then quantify its characteristics, which were statistically analyzed for validation and effectiveness in reference to parameters established in the Langley method (2018). The sample was 80 digital images of skulls (ranging from 30 years to 50 years) following what was proposed by forensic identification techniques for determining sex in bone structures. As a technique, an exhaustive analysis of the skulls of a specific population was used to identify the sexual characteristics that allow sex to be determined (morphological characteristics of the glabella, zygomatic extension and mastoid process). Being the degree of agreement by the Kappa test linear for the measurements of glabella, zygomatic extension and mastoid process, determining that observer 1 and observer 3 their values are between the ranges of 0.81

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.

Objective: To determine how environmental factors influence the determination of blood groups in bloodstains of criminal interest. Lime, 2019. Materials and methods: This research used the hypothetical-deductive method, with a quantitative approach, basic type, non-experimental cross-sectional design and explanatory level. The population consisted of 270 samples consisting of blood stains prepared on polycotton fabrics of blood groups A, B and O, using a non-probabilistic method for selection. The technique used is observation and the data collection instrument was an observation guide. Results: According to the results obtained, we found that the effects of humidity and temperature on group A bloodstains give strongly positive results up to week 7, lowering the avidity to 1+ at week 10. In the case of blood group B stains the effects of humidity and temperature allow to demonstrate positive results up to week 9. No agglutination is observed at week 10. Group O blood spots, subjected to the effects of humidity and temperature, were positive during the ten weeks of the study, but with low avidity at week 10. Conclusions: According to the results obtained, it can be concluded that environmental factors such as humidity and temperature do not significantly influence the determination of blood groups of criminal interest, however, the exposure time can lower the avidity of the results.

(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.
