Is this a legal or possible way to solve a double murder, that is if the DNA at the crime scene wasn't a match to anyone in the database. Just because one passes a polygraph and operates well under questioning doesn't make them innocent, IMO, some people can pass both even though they are guilty.
sure LE can *ask* people to randomly give their DNA...but it would be on a voluntary basis.... and I *doubt* that any one of the murders in this case would voluntarily give their DNA.
