“…La Real Academia Española (RAE, 2020) la define, como el "estudio de los indicios de un hecho criminal, con el fin de determinar todos los datos posibles relativos a la víctima o a las circunstancias del crimen". En este sentido, en la criminalística de campo (Rankin-Turner et al, 2018) se levantan todos los indicios que puedan constituir evidencia, tanto de objetos como de restos de fluidos corporales (Ahannach et al, 2021), el olor de la descomposición humana (Oostra et al, 2020), el intervalo post-morten (Dash & Das, 2020;Zhang et al, 2021), y olores que permanecen en la escena criminal (Ferry et al, 2019). La anterior disciplina se rige por principios básicos (figura 6) que contribuyen al análisis, descubrimiento, interpretación y esclarecimiento del hecho criminal (Montiel, 2017;Durán et al, 2019).…”

Los indicios biológicos en escenarios criminales suelen pasar desapercibidos para los sentidos humanos,y existe evidencia del empleo de caninos para su detección. Esta revisión tiene como objetivos: analizar el papel de los equipos caninos para el rastro de cadáveres, secciones anatómicas y fluidos biológicos en escenarios criminales; conocer la procedencia de los insumos biológicos como sustancias controladas para el entrenamiento; y, determinar los alcances e importancia de los caninos en el campo forense. Se realizó una revisión documental de publicaciones en bases de datos académicas entre los años 2000 y 2021, bajo el método cualitativo con un papel hermenéutico-interpretativo. Se llevó a cabo un análisis desde los referentes académicos, y se determinó la importancia de estos estudios en contextos de investigación criminal, criminología y victimología. Como conclusión, se evidencian las posibilidades técnicas que ofrecen los caninos en los protocolos forenses, a partir de la estandarización para el manejo de las muestras, el almacenamiento y el futuro de las investigaciones para la gestión de estudios periciales en contextos reales, con el propósito de garantizar el cumplimiento de la Cadena de Custodia, que conlleven a un desempeño exitoso de los binomios bajo una certificación y validez probatoria en el proceso penal.

“…For the experiments we used the match-to-sample-likeprotocolemployed in forensic odorology and scientific research 23 , 37 , 38 this method is described in detail by Rodionova et al 23 . In general terms, the procedure consisted of the dog being encouraged to sniff a tube containing a urine sample from a donor with transplanted hepatocarcinoma (odour to search, initial sample), and then prompted to choose from 12 similar tubes in a lineup, among which was a sample of another donor with transplanted hepatocarcinoma (test sample).…”

Trained detection dogs distinguish between urine samples from healthy organisms and organisms with malignant tumors, suggesting that the volatile urine metabolome contains information about tumor progression. The aim of this study was to determine whether the stage of tumor growth affects the chemical differences in the urine of mice and to what extent the "olfactory image of disease" perceived by dogs coincides with the "image of disease" recorded by the mass spectrometer. We used a novel laser ionization mass spectrometry method and propose a mass spectrometric analysis without detailed interpretation of the spectrum of volatile metabolomes in urine. The mass spectrometer we use works without sample preparation and registers volatile organic compounds in air at room temperature without changing the pH of the sample, i.e. under conditions similar to those in which dogs solve the same problem. The experimental cancer models were male BDF-f1 hybrid mice transplanted with hepatocarcinoma tissue, and similar mice transplanted with healthy liver tissue were used as controls. Our data show that both dogs and our proposed laser mass spectrometry method are able to detect both the entire spectrum of volatile organic compounds associated with the disease and minor changes in this spectrum during its course.

“…As noted, most research on police K9s is unrelated to their use as a police weapon. Instead, there is a relatively robust research literature concerned with their olfactory abilities (Jezierski et al, 2016;Kokocińska-Kusiak et al, 2021), whether it be for cadavers (Komar, 1999;Riezzo et al, 2014), explosives (Lazarowski et al, 2020) and arson (Scott, 2014), suspect scent lineups (Ferry et al, 2019), or narcotics detection (Abdel Fattah & Gharib, 2020). Relatedly, researchers have investigated the impact of handler beliefs on K9 detection performance (Lit et al, 2011(Lit et al, , 2019.…”

Objectives: Test the immediate and sustained impact of suspending a police K9 program on officer injury, suspect injury, and suspect resistance rates.Methods: A large municipal policing agency housing one of the oldest K9 programs in the U.S. suddenly terminated the program at the close of summer 2020. We exploit this change as a natural experiment to test three hypotheses related to rates of injuries (officer and suspect) and resisting arrest. We use Bayesian modeling in an interrupted time series analysis to measure the immediate and long-term effects of the K9 apprehension program's suspension on our hypotheses.Results: The sudden suspension of K9 apprehension was not associated with a statistical increase in officer or suspect injury, or suspect resistance, during felony arrests. Conclusions: As police agencies, communities, and stakeholders renegotiate the risks of policing, constraints on using police K9s are unlikely to impact aggregate officer or suspect safety negatively.
