Metropolitan Police detectives are investigating a suspected double rapist by using DNA information to identify potential relatives of the suspect. According to reporting from multiple outlets, investigators work through a list of men who share familial DNA with the suspect. The list is compiled by the National Crime Agency (NCA) and is based on partial genetic matches that can indicate shared ancestry rather than an exact DNA profile match.
The police action focuses on narrowing down who could be connected to the suspect through family ties suggested by the genetic evidence. Detectives then review individuals on the NCA-generated list as part of their broader investigative process, which may include other intelligence, background checks, and additional forensic or investigative work.
The coverage does not indicate that any individual on the list has been confirmed as the suspect; rather, the approach is described as a step to trace possible relatives and help identify the person responsible for the alleged offences. The case is ongoing, and further developments would depend on how those leads are investigated.
