Minnesota cold-case suspect alleges constitutional violations in DNA database search Private services intended for individuals to conduct genealogical research have increasingly been used by police and researchers to crack long-unsolved crimes, but the tactics present legal issues that have never before been litigated in Minnesota. 10:23 am, Jul. 1, 2021 × Michael Carbo Jr. VIRGINIA, Minn. — The Chisholm Police Department's hiring of a private company to comb DNA databases in search of the perpetrator in a decades-old killing was illegal, and all evidence obtained as a result should be tossed, a defense attorney argued. Public defender J.D. Schmid said law enforcement, in cooperation with Parabon NanoLabs, searched two databases without warrant or consent from people whose genetic information was disclosed, in violation of Minnesota law and the state and federal constitutions.
