:waitasec:Just wanted to ask a quick question as far as the coffee cup "evidence" goes.
Even if they WERE to get DNA or some sort of fingerprint evidence from that cup...and even if it DID belong to a potential abductor, the only way they are going to catch this person is IF they have been arrested before and had some sort of fingerprint or DNA to match against some sort of database, correct?
If this is a first time perp chances are even full blown DNA recovery isn't going to match up to anything that is going to point to the person responsible...or am I missing something?
We are basically praying that the coffee cup DNA would match someone who has already been arrested, fingerprinted, and DNA swabbed (if indeed it was relevent to the case).
:waitasec:
I'm less inclined to consider DNA as I would fingerprints on that cup. Fingerprints are not only easily lifted from paper, but they stay there a long time -- unless exposed to water. As it rained up until about 11AM that morning, if fingerprints are lifted, it could indicate that the cup was left there after 11AM on Friday the 13th (as it didn't rain after that time).
While a paper coffee cup in no way by itself indicates a connection to a crime, IF there are fingerprints, and IF a suspect is pinned down and fingerprinted, then it can establish they were there that day (or later).
LE, if they suspect someone, have been known to, shall we say, follow that suspect around, AND it is legal to, say, recover something tossed away by that person in a PUBLIC TRASH CAN (or area) to lift prints/DNA from. With that scenario, they do not need the person's permission to be fingerprinted or swabbed.
Just a thought and... MOO
