What modern techniques are being used to solve cold cases?
Modern techniques such as DNA analysis, particularly familial DNA testing, have revolutionized the way cold cases are approached. For instance, in the recent case of George 'Dod' Murdoch's murder from 1983, police have identified 200 potential genetic matches linked to a DNA profile developed from the crime scene. This method allows investigators to connect with relatives of potential suspects, providing new leads in long-unsolved cases.
