DNA and Cold Cases

I'm sure most of you have been hearing or reading about DNA being used to solve cold cases.

Genealogists are being called in to help trace family trees using the DNA taken from forensic evidence. They then look for matches using GedMatch which is a free tool where anyone can upload their DNA results.

Once a match is found, detectives can focus on family members connected to that match or matches.

There are two opposing opinions on this somewhat controversial new tool of course. I think it's a fascinating use of DNA and so helpful to law enforcement.

Imagine taking a killer off the streets and putting him/her somewhere where he/she can't hurt anyone else. Imagine the relief and feeling of closure of family members who finally know who hurt or murdered a love one.

Some think this is an intrusion and disagree with the blind searching which ends up matching people who are not suspects but are connected to them through DNA.  In other words you could find that you match a criminal - a distant cousin, someone you don't know, someone you do know.....

Because of the controversy, GedMatch now has a warning when a user logs in.

"April 28, 2018 While the database was created for genealogical research, it is important that GEDmatch participants understand the possible uses of their DNA, including identification of relatives that have committed crimes or were victims of crimes. If you are concerned about non-genealogical uses of your DNA, you should not upload your DNA to the database and/or you should remove DNA that has already been uploaded. Users may delete their registration/profile and associated DNA and GEDCOM resources."

Personally my opinion is if someone I'm related to commits a crime, they deserve to face whatever our justice system deals out. I would be glad if my DNA helped bring them to justice, and gave closure to a family.

In any case, here's an interesting article talking about five cold cases that were solved using DNA.
