Familial DNA in Policing
This week we examine familial DNA. Many people are putting their DNA into databases such as 23 and Me and others to find out their genetic backgrounds and search for possible relatives they do not know. Answer the following questions for this week:
Should police be allowed to use this database to solve crimes?
If you did not put your DNA in this database but a family member did, do you feel this is an invasion of your privacy?
Find a case where familial DNA was used to catch the suspect in the case and explain how this was one.

Police Use of Familial DNA Databases
Police use of familial DNA databases to solve crimes raises both support and concern. On one hand, using these databases has helped solve violent cold cases that otherwise lacked evidence. DNA from family members can lead to partial matches, allowing law enforcement to narrow down suspects. This method has successfully identified criminals when traditional forensic tools failed. For example, the Golden State Killer was apprehended in 2018 using genetic genealogy from GEDmatch. His distant relatives’ DNA profiles enabled investigators to build a family tree and pinpoint him as the suspect. This case highlighted the potential power of familial DNA in delivering justice.
However, there are growing ethical concerns. While solving crimes is a clear benefit, privacy implications remain serious.

Invasion of genetic privacy can erode trust in scientific research and public databases. Families may unknowingly expose each other to law enforcement scrutiny, which can feel intrusive. As DNA technology evolves, regulations and ethical standards must also develop………
