Lorsque du sang liquide est soumis \u00e0 diff\u00e9rentes forces physiques, des taches et des patrons de taches de sang sont d\u00e9pos\u00e9s sur des surfaces vari\u00e9es. L\u2019analyse des taches de sang (BPA) repose sur l\u2018observation de la forme, la taille, la direction, la distribution et la dispersion (arrangement) de celles-ci dans le but d\u2019identifier un m\u00e9canisme de cr\u00e9ation. Les patrons de taches de sang peuvent apporter des informations importantes concernant les \u00e9v\u00e8nements qui ont men\u00e9 \u00e0 leur cr\u00e9ation. De plus, ces informations peuvent mener \u00e0 la reconstitution, en tout ou en partie, de la s\u00e9quence des \u00e9v\u00e8nements et\/ou \u00e0 l\u2019\u00e9valuation de d\u00e9clarations de t\u00e9moins et de suspects.<\/p>\n\n\n\n

L\u2019analyse d\u2019une sc\u00e8ne d\u2019\u00e9v\u00e9nement est un processus complexe. En effet, sur une sc\u00e8ne de crime, les patrons produits par diff\u00e9rents m\u00e9canismes peuvent se superposer et donc pr\u00e9senter des caract\u00e9ristiques de diff\u00e9rents types de taches de sang. La forme et la nature des surfaces \u00e9tudi\u00e9es affectent \u00e9galement l\u2019apparence des taches de sang. L\u2019\u00e9tendue et la complexit\u00e9 d\u2019une sc\u00e8ne d\u2019\u00e9v\u00e9nement sont aussi influenc\u00e9es par le d\u00e9placement possible de la source de sang ainsi que par la disposition des objets pr\u00e9sents sur les lieux.<\/p>\n\n\n\n

Les premi\u00e8res \u00e9tudes en taches et projections de sang ont \u00e9t\u00e9 publi\u00e9es en 1895. La recherche dans cette discipline des sciences forensiques poursuit son expansion et le d\u00e9veloppement de nouveaux outils et de nouvelles m\u00e9thodologies am\u00e9liorera encore le travail des analystes en taches et projections de sang.<\/p>\n","protected":false},"excerpt":{"rendered":"
