(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

Factores contaminantes en la escena del crimen desde la percepción del personal médico legista para determinar la causa de muerte preliminar en unidades medicolegales, Perú 2024
(Universidad Privada Norbert Wiener, 2025-06-17) Carlos Cordova, Janeth Eliana; Salazar Manrique, Ana Paulina; Montellanos Cabrera, Henry Sam
Esta investigación estableció el objetivo de analizar cuáles son los factores contaminantes en la escena del crimen desde la percepción del personal médico legista para determinar la causa de muerte preliminar en unidades medicolegales, Perú 2024 y se enmarcó dentro del marco metodológico del enfoque cualitativo, método inductivo, de tipo básica, con diseño fenomenológico. Los participantes fueron 15 médicos legistas de diversas unidades medicolegales del Perú. La técnica que se empleó fue la entrevista y el instrumento fue la guía de entrevista semiestructurada, que contó con 17 preguntas, organizadas en tres subcategorías a priori. Los resultados permitieron notar que las tres subcategorías propuestas existen dentro del contexto estudiado y su ocurrencia se da a partir de diversos factores que han sido profundamente analizados. Se concluyó que los factores contaminantes en la escena del crimen son los factores humanos, factores ambientales, factores físicos y químicos, a partir de los cuales también se organizaron los hallazgos y los factores inmersos en la escena del crimen.

Limitaciones de la identificación facial, mediante el sistema Morpho Face Investigate, de la oficina de criminalística policía nacional del Perú Cusco, 2019
(Universidad Privada Norbert Wiener, 2025-09-13) Bolívar Caytuiro, Frinné Elena; Orellano Benancio, Lizbardo
Objective: To determine the relationship between limitations of facial identification with the use of the morpho face investigate system, from OFICRI Peru’s National Police Cusco, 2019. Materials and methods: Non-experimental, correlational study. There was a population of 103 expert reports archived in the facial biometrics-MFI section of the OFICRI PNP Cusco, for which observation technique and a data collection sheet were used as an instrument. Results: 103 expert reports were analyzed, according to the correlation of Rho de Spearman it has a probability P=0.000 of relation is significant at 1%. , where the technology and internal links of the MFI system has a coefficient of 0.748 and with external links 0.605, between image and internal links of the MFI system has 0.483 and external links 0.369, between the environmental factors and internal links of the MFI system is 0.413 and external links of 0.359, the correlation between facial identification and use of the MFI system, it has a 0.598.Conclusion: Research has found that the limitations of facial identification, such as technologies, images, environmental factors influence image recognition through the MFI system, at the same time this prevents links in the database of the same system as that of RENIEC, resulting in minimal results in an identification by facial features.
