Abstract
In this paper, we discuss the DNA results obtained from the analysis of cellular material located beneath the fingernails of two women in separate cases of homicide. In both cases, the deceased females had been submerged in water, the first in bath water and the second in seawater, for 2 and 3 h, respectively. Mixed DNA profiles were obtained in each case indicating the presence of foreign DNA in these samples. These results indicate the valuable forensic evidence that can be obtained from samples that may be considered unlikely to provide DNA results and the high priority that should be placed on the routine DNA analysis of material from deceased's fingernails, regardless of the scenes that they are found in, including submersion in water.
