What would you think if you were the cop doing the interview and couldn't
get back in the interview room? How would you write your report?

I'd wait until he was done, note what he wiped his hands on and
then send it out for DNA testing. Don't need a warrant if he has
abandoned the sample (another reason to not drink water, etc., while in
custody)
