Sumisión química en casos de presuntos delitos contra la libertad sexual analizados en el Instituto Nacional de Toxicología y Ciencias Forenses (Departamento de Madrid) durante los años 2010, 2011 y 2012

Abstract

IntroductionDrug-facilitated sexual assault crimes can be applied in cases of covert administration of certain substances, as well as cases in which the victim voluntarily consumes these same substances. Materials and methodsThis study describes retrospectively cases of sexual assault related to the consumption of chemical substances. They were reported to the Madrid Department of the National Institute of Toxicology and Forensic Sciences during 2010, 2011 and 2012. We collected information related to the victim's profile, the type of biological samples given and the results of the toxicological analysis. ResultsOut of 306 cases of sexual assault or abuse referred, 107 have met the inclusion criteria. The victim's profile is of a young Spanish or Latin-American woman (mean age: 25.9 years) who admits to consuming alcohol prior to the episode and suffering from total or partial amnesia with regard to the facts. The given samples were blood (27.1%), urine (14%) or both (57%). Toxicological analysis was positive in 87.9% of cases and the substances identified were ethanol (61.7%), pharmaceuticals (40.2%, mainly benzodiazepines), and illicit drugs (27.1%, primarily cocaine) either alone or in combination. ConclusionsThis study reflects the requirement to work in prevention and training of potential victims and healthcare personnel, proves that an early and adequate collection of samples are key factors to confirm the diagnosis and identifies that detected licit or illicit substances belong to a frequent consumption pattern.
