Abstract: | Physical contact between two or more persons can give rise to the transfer of DNA from one person to another and biological material can accumulate under the fingernail hyponichium. The purpose of this study is to value the normal levels of foreign DNA profiles under the fingernail of individuals deceased of a non-violent death, in order to define the usefulness of this approach in the recovery of a suspect's DNA profile. No foreign DNA was found in the majority of the cases. |
