DeAngelo did not own his DNA sample, as he had “voluntarily submitted it” while murdering two people in their home. LE took ownership of it and they in turn voluntarily submitted it to the GEDMatch site. There is no current law prohibiting LE from submitting DNA profiles obtained in a legal manner to genealogy web sites. The investigators got a fair amount of advice from legal experts before they did this, according to the reports I have read about it.
