I'm with you but duct tape has a heavy amount of adhesive on it which leaves strong fingerprints (its even adheres to skin tightly making a smeared print extremely difficult achieve...your fingers don't slide they "snap" on and off duct tape). If the dna was skin cells it would more than likely be from the lips and therefore also containing saliva.
Again, all this is speculation and I could be wrong, but I also don't think this could be "first offenders". If there was fingerprints on the tape they would have showed who did it in the database unless this case gets weirder and it was someone who had never been arrested or fingerprinted.
