familial DNA searching

Familial DNA searching is a forensic technique used to identify potential relatives of a suspect or missing person through DNA profiles stored in databases. When the DNA from a crime scene does not match any known profiles, investigators check for close matches, suggesting that the DNA belongs to a family member of the suspect. This method can help narrow down suspects by exploring familial connections and is particularly useful in solving cold cases, providing leads when traditional investigative methods have stalled. It raises important ethical and privacy considerations regarding genetic information and familial relationships.
