The thing is in US there is so little security camera, who ever did the crime is very easy to get away with that. Back to my home country, CCTV is everywhere, I mean in every corner of every street in every city( the country side is not that well equipped). Here in US, people live far apart and no camera at all. Crime is hard to solve. Also, since male's DNA Y comes from only males in the family. If you can check all Delphi's male's DNA, assuming LE did get BG's DNA from the scene, it would be very easy to get his family relationship map out. But in USA, privacy is most important, almost always more important than safety of the community, the DNA thing won't work. But give a shout out encourage people to come forward to take DNA test may help? Does there is a law preventing LE to take a DNA test to a regular criminal ( Not only RSO)?
