Probably don’t want the public to know how DNA is shared from health screening or genealogy sites with the government to prosecute cold cases.
The DNA forensics they performed are largely already publicly disclosed. There’s a DeAngelo family tree available online. I think the public deserves to know everything about this bastard insofar as it doesn’t infringe on his right to a fair trial. I want to know what they found in his house, his cop schedule with the Exeter and Visalia PD’s, and his employment/life/movements during the 79-91 “mystery years”. I hope they go over his life and movements with a microscope.
