Here is described a sibling incest case involving a brother and his underage sister, both native from Ivory Coast. A police investigation was conducted, and suspects were restricted to two subjects, specifically the father and older brother of the underage girl. However, no clear indication of the perpetrator could be obtained, and therefore the judge demanded a paternity testing. DNA analysis was conducted on the underage girl, her daughter and her older brother, while the father's victim refused to provide his own DNA sample. The analysis of autosomal STRs was supported by X-STRs. As expected, the latter analysis proved to be decisive in the resolution of the case, confirming that the brother was the female newborn's father and the rapist of his underage sister.
