Abstract (EN): The social situation in the past years has led to increase in the paternity test with absent parents in Colombia. We present here three cases of biological relationship investigation of an extramarital son without parents; the first case is the biological relationship research between granddaughter and grandparents with dead parents, the second one is between niece and three paternal uncles without father and mother and the third one is between grandson and grandparents with dead parents. In the three cases the research started with the typification of 15 autosomal STRs markers. Cases 1 and 2 were complemented with X-STR markers and Case 3 was complemented with Y-STR haplotype, all cases were solved with a conclusive diagnosis. This report shows the efficiency of STRs markers linked to sexual chromosomes, like complement, when autosomal STRs are not allowed to get the necessary probability.
