  • Positive DNA Sample from Pizza?

    http://www.cnn.com/2015/05/21/us/dc-...-money-motive/

    I'm perplexed about the claim of DNA evidence so soon after the crime, since it's my understanding Iit takes several weeks to develop reliable DNA profiles. If this is accurate information, the technology must have improved tremendously. ..would it be enough to hold up in court?

    Can anyone tell me if they could in fact develop reliable profiles in just a few days?

    I think it only takes a day or two to get DNA results. Most of the delay is the backlog at the lab doing the testing.

    Unless this is CSI, then they just point a scanner at the pizza, get a 3D hologram of it, complete with spectroscopic analysys, fingerprints, and DNA profiles in about 2 minutes.

        Well ok. I've read that on average it takes three weeks, and my impression was, aside from lab backlog, it was because the profiles took time to develop.

        Ain't CSI great though? LOL.

          Looks like they've taken his DNA before. So matching the unknown DNA to him would be a simple matter of replicating the sample and seeing if the database has any match.

            My dear DesertBerean. Backlog?

            A rich CEO and his family was murdered. The neighbourhood of multimillionaires and their families need to be assured that they will be safe from such assaults from low-life thugs. The Vice President, for crying out loud, Biden himself lives in the vicinity.

            Backlog? This case is priority number one.

              I think it takes around 50-60 hours to do the lab, and a lot of it is procedural record keeping, making sure the sample is pure and not contaminated with previous tests, etc.

                  I remember seeing a parody of CSI where they kept zooming in on a satellite photo in order to pick up a fingerprint and then extracted the DNA from the photo of the fingerprint to make an instant identification.

                  I'm always still in trouble again

                        That may be...but not much of a point if the sample did actually require three weeks. but it appears that isn't the case.

                          Right, so since that question has been answered, shall we move forward to contextualise this otherwise isolated incident within class warfare so as to properly understand it?

                            How about you read this
                            http://www.foxnews.com/us/2015/05/22...cide-arrested/ and decide if it's a case of class warfare, or a very scary instance of a very dangerous murder suspect?

                              I always like those computer forensic shows where they are trying to track a hacker. And they say something like "His IP address is bouncing off dozens of servers, we can never find him!"

                              Well first of all that is a trace route. They have to have the actual IP to even start a trace route. The IP might be hidden through a TOR anonymizer and that would stop it. But if not, they already HAVE the guys location, regardless of where it bounced around to get to the end. And if they did want to trace the route back through the servers, going through "dozens of servers" is not a problem. That is what they have computers for.

                              Plus most of the time, the IP address only shows you the location of the DNS server (the ISP) and you would have to contact them with a court order to find who they assigned that IP address to.

                              For example, looking up DB's IP, I can tell what city she is in and what state (California) but I can't see her actual location. I can also tell she is using Verizon wireless.

                              And she was eating cheetos. Wearing a pony costume. while singing "itsy bitsy spider" - but that's all I can tell, I swear. except for her ATM PIN and social security number.
