The Portuguese authorities applied a DNA test to the saliva sample found on the cover of one of the beds in Madeleine McCann's room. The sample had been collected the day after the girl's kidnapping, which occurred on May 3, 2007.
The profile obtained consists of 17 autosomal STR markers plus a sex marker (amelogenin). The latter, XY, indicates that the DNA belonged to a man.
Finally, with that DNA profile, a person, C.G., has been identified, unrelated to the crime.
