The DNA from the services is not submitted to the court. What it does is narrows the suspect pool. Police then obtain a different DNA sample from the suspect, either by picking up a discarded cigarette or cup or by taking a cheek swab. It is this evidence that is submitted to court.
All the Ancestry/23andMe service does is narrow the suspect pool. Not saying it isn’t creepy, but it isn’t directly used as evidence
Yes. I understand what you are saying but if my sister sends a sample to an alleged private DNA service and the police obtain that sample, I do not think that is kosher. If they approached my sister and asked her for her DNA, I do not believe they can compel her to submit a sample without a court order.
What they have been doing is getting sample that is close, say from my sister. Follow me around and grab my coffee cup and use that sample. How can they legally obtain the information from the private DNA service? How would they know my sister sent it in, assuming they have their suspect pool narrowed that fine. There is a case here in the SF area where they got a close match to a suspect, narrowed the suspect pool after that. IN other words, the person they eventually arrested they didn’t know existed until they obtained a relative’s sample from the DNA service. They then determines she had a relative in the SF area (she was in Ohio). IN other words, it was a big fishing expedition.
