\nUrmele de sange, prin frecventa cu care sunt intalnite in <\/span>campul infractional, ca si prin posibilitatile de identificare pe care le ofera, inclusiv prin furnizarea de indicii necesare clarificarii imprejurarilor privind locul, timpul, mijloacele si modul de savarsire a faptei, detin o pondere particulara in cadrul in-<\/span>vestigatiilor criminalistice.<\/span><\/div>\n
\nDupa cum se cunoaste, sangele define aproximativ 1\/13 din greutatea unei persoane si se compune din doua parti principale: plasma si elementele celulare, formate din globule rosii (hematii sau eritrocite), globule albe (leucocite) si trom-<\/span>bocite, fiecare distingandu-se printr-o serie de caracteristici.<\/span><\/div>\n
\nCuloarea urmelor de sange <\/span><\/i>difera in functie de vechimea, cantitatea, natura suportului si factorii care actioneaza asupra lor: temperatura, lumina, diversj agenti <\/span>fizici si chimici. <\/span><\/span><\/div>\n
\nCalitatea urmelor de sange <\/span><\/i>poate fi influentata de actiunile exercitate de om, respectiv de persoana care cauta sa indeparteze pata prin razuire, spalare sau, pur si simplu, prin distrugerea suportului sau a portiunii sale care contine urma, cum ar fi, <\/span>de pilda, arderea prosopului, a batistei, decuparea unei portiuni <\/span>din material .<\/span><\/span><\/div>\n
\nDescoperirea urmelor sangvinolente <\/span>reprezinta o activitate de o deosebita <\/span>importanta.<\/span><\/div>\n
\nCautarea urmelor de sange se efectueaza potrivit particularitatilor locului sau suportului cercetat, deci in functie de fiecare caz in parte, ea fiind orientata in cateva directii principale, si anume:<\/span><\/div>\n
\na.<\/span> Imbracamintea si  corpl   persoanelor <\/span><\/i>antrenate in infractiune (victima <\/span><\/span><\/div>\n
\nb.<\/span> Portiunea de teren fi obiectele <\/i>aflate la locul savarsirii infractiunii sau in
\nlocul in care a fost descoperit cadavrul, cum sunt, de pilda, covoarele, incheieturile parchetului, ale dusumelei, diversele obiecte de mobilier, zidurile, usile, ferestrele, solul, vegetatia \u00a7.a.<\/span><\/div>\n
\nc.<\/span> Instrumentele <\/i>folosite in savarsirea infractiunii, cum sunt cutitele, topoarele,
\nalte tipuri de arme, instrumentele chirurgicale intrebuintate la efectuarea ilegala a unei interventii.<\/span><\/div>\n
\nd.<\/span> Instalatiile sanitare, <\/i><\/span>vasele, alte obiecte ce ar fi putut servi la inlaturarea
\nurmelor sau la transportul cadavrului.<\/span><\/div>\n
\n<\/div>\n
\nRidicarea urmelor de sange <\/span>prezinta anumite particularitati, indeosebi in cazul celor care se gasesc pe obiecte ce nu pot fi transportate. De pilda, daca petele sunt uscate, ele se pot razui sau racla impreuna cu o portiune din suport. Daca se prezinta sub forma unor balti, se pot absorbi cu pipeta sau cu hartia de filtru. Urmele dispuse pe suprafete ce nu se pot razui sau aschia se solubilizeaza si se ridica pe o hartie de filtru, insa vor trebui examinate cu maxima urgenta.<\/span> La ridicarea urmelor sangvinolente trebuie avut in vedere ca acestea pot contine <\/span>si alte categorii de urine biologice cum sunt, de exemplu, fire de par, resturi de tesut etc., carora trebuie sa li asigure integritatea.<\/a><\/span><\/div>\n

<\/p>\n

\n Intcrpretarea urmelor de <\/span>sange la locul descoperirii lor este o activitate cu rezonanta in clarificarea ulterioara a imprejurarilor savarsirii faptei. Dupa forma <\/span>luata de o picatura de sange, se poate stabili inaltimea de la care a cazut, marginile urmei fiind cu atat mai zimtate cu cat inaltimea este mai mare. O urma de sange creata de o persoana in mers are o forma alungita, apropiata de aceea a unui semn de exclamare, cu partea ascutita in directia deplasarii. De asemenea, dupa forma, <\/span>dispunerea si cantitatea stropilor, se poate stabili daca <\/span><\/div>\n
\n<\/div>\n
\nCercetarea urmelor seminale<\/span><\/div>\n
\nUrmele seminale pot reprezenta nu numai dovada unei infractiuni dar aduc precizari in legatura cu mobilul si natura faptei.<\/span><\/div>\n
\nCautarea urmelor seminale <\/span>impune examinarea corpului victimei, o atentie speciala fund acordata orificiilor naturale (examinare realizata de catre cadre medicale), precum \u00a7i a lenjeriei de corp \u00a7i de pat, a Imbracamintei, a altor <\/span>obiecte. Spre deosebire de alte urme biologice, urmele de sperma sunt mai u$or de <\/span>descoperit datorita fluorescentei lor relativ specifice, de nuanta albastruie, determinata <\/span>de radiatiile ultraviolete. PrecizSm, insa, ca fluorescenta nu este o indicate de cer\u00ad<\/span>titudine, ci numai una cu caracter de orientare.<\/span><\/div>\n
\nRidicarea urmelor seminale <\/span>necesita, poate mai mult decat in cazul altor urme biologice, precautie deosebita pentru pastrarea intacta a petei si implicit a <\/span>spermatozoizilor, principalul element asupra caruia se indreapta examinarea. Pentru aceasta, se ridica Intreg obiectul purtator de urme sau se taie portiunea cuprinzand pata, fara a se indoi.<\/span><\/div>\n
\nInterpretarea la fata locului a urmelor seminale <\/span>ofera date referitoare <\/span>nu numai la natura, mobilul \u00a7i modul de savarsjre a faptei, ci $i in Iegatura cu anu\u00ad<\/span>mite deprinderi, aberatii sexuale sau anumite stari psihopatologice ale autorului.<\/span><\/div>\n
\nExpertiza biocriminalistica a urmelor seminale <\/span>este destinata stabilirii <\/span>faptului daca urma este intr-adevar de sperma si daca aceasta este de origine umana <\/span>sau animala. <\/span><\/div>\n
