Relative’s DNA Leads Police to Criminal
James Davies committed three serious sex attacks over two years but was never caught. Five years later, the semen he left at the crime scene was found to match 15 different markers of a DNA sample on file in the UK National Criminal Intelligence DNA Database. That DNA sample turned out to be a family member’s. (Police will not say who it was but it was most likely a parent, child, or sibling.)
Since the Criminal Justice and Police Act of 2001, DNA samples can be collected from anyone who has been arrested in the UK whether or not they’re charged or proven guilty. The UK’s national DNA database now has DNA from more than 4.5 million people.
As I’ve mentioned before, the information your DNA holds not only says something about you, it also says something about your family members. For example, if your mother tested positive for the gene that causes Huntington’s Disease before she started exhibiting symptoms, you’d know that you were at 50% chance of inheriting the gene too.
