sciencewatcher writes "In an attempt to solve a rape and murder of a 16-year-old girl, the Dutch police have asked 8080 men to provide their DNA. All these people lived 5 km or less from the crime scene at the time of the murder. This reopened cold case is the first large-scale attempt not to hunt the rapist and killer but to locate his close or distant male relatives. All data gathered will be destroyed after the match with this particular murder. There seems to be great public support for this attempt." Shades of The Blooding.
