My wife and I watch a lot of true crime stuff like "On the Case", "Homicide Hunter", and "Dateline". DNA testing has really evolved into one of the biggest payoffs for solving cold cases sometimes that were unsolved for up 40 years. To broaden the scope of a search, law enforcement has been able to use other DNA databases like Ancestry DNA and Heritage for example. Recently, the Golden State Serial Killer was matched using this method where one of his relatives submitted their DNA to research their family tree. Another case solved was of Christy Mirack - https://www.theguardian.com/us-news/2019/jan/08/pennsylvania-dj-dna-schoolteacher-murder The same type of investigating has been used to prove the innocence of people falsely accused of murder.
So, whom does your DNA belong really belong to when submitting it to a company? Do you think its ethically alright to use your DNA?
