I may have missed it, but I have relatives that works at the Chrysler plant in Kokomo and a man was walked out in handcuffs for DNA and questioning. He hasn't been arrested yet, so I won't give his name. However he has a 1989 attempted rape conviction of an 11 year old by knife point.
JMO but that might make sense from a dna perspective because at the time he was convicted they wouldn't have been yet collecting dna from registered sex offenders, so he might not be in the system.
