I wonder about the DNA. I had heard from reliable sources that there 4 four markers. I know that 4 markers are enough to eliminate a suspect. However, I don't believe 4 are enough to identify someone beyond a reasonable doubt.In some states, DNA from an offender only hits the database if it's a sexual offense. This crime had sexual overtones that may have been part of an elaborate smoke screen.
Bottom line, if this guy wasn't a true sex offender, then a DNA match might not happen regardless.
