In many sex crime cases, there is no DNA evidence found that can be used at trial. However, for the cases that do involve DNA evidence, it can be difficult to build an effective defense. An experienced criminal defense attorney, though, can determine if there was an error when the evidence was collected, stored or processed -- all of which can provide reasonable doubt in the minds of a judge or jury.
DNA is found in every cell in our bodies. It determines the color of our skin, hair and eyes. It is found in blood, sweat, urine saliva, skin tissue and semen. On an alleged victim of rape or similar sex crime, DNA might be found on his or her body or clothing, on furniture, drinking glasses, cigarette butts and more.
