Partial DNA Matches Raise More Questions, Answer Few In Duke Lacrosse Case

DURHAM, N.C. -- Defense attorneys say there's no conclusive link between DNA evidence and members of the Duke lacrosse team after a second round of tests. While they consider the results definitive, what do the tests really show?
The report report on the second round of DNA testing that was released to defense attorneys late Friday by District Attorney Mike Nifong says DNA from multiple members of the Duke lacrosse team was found on a press-on fingernail worn by the accuser -- an exotic dancer who performed at a March 13 team party in Durham -- and discarded in the bathroom. However, defense attorneys said the report only contained partial matches to the players' DNA.
When a DNA test is run, technicians compare different segments on the DNA. A partial match means that parts of the DNA tested are too blurry to make a conclusive match, but the other parts match so perfectly that the person cannot be ruled out.
According to defense attorney Karl Knudsen, who is not connected to the Duke lacrosse case, the report establishes little.
“The actual results were a little bit unclear,” said Knudsen. “There’s DNA, and there’s DNA. If the DNA had been semen identified to a particular player, that would conclusively establish two things. One, that there was sex, and two, that there was a particular player that participated.”
But Knudsen said the DNA could be anything ranging from dandruff to saliva, and that it could be just as compatible with guilt as it is with innocence.
Defense attorneys involved in the case say that the fingernail was found in a trash can, along with cotton swabs, tissue, toilet paper and other items that would carry the DNA of people who used the bathroom.
According to defense attorneys, a key point the report makes is that the accuser had sex with another man who was not a Duke lacrosse player. However, Knudsen said that it could be a little less relevant to the case if the unidentified male is a person known to the accuser, because that might mean that the DNA had been there five to six days prior to the alleged incident.
A grand jury has charged sophomores Reade Seligmann, of Essex Fells, N.J., and Collin Finnerty, of Garden City, N.Y., with rape, kidnapping and sexual assault.
Nifong is expected to use the results from the second round of DNA testing as he brings his case against another Duke lacrosse player before a grand jury on Monday.
I am not a rabid fan of CSI, and I am not a forensic DNA expert, but I have two observations:
1. I don't believe this is true that DNA could remain there for almost a week.
2. If true - gross.

UGH..It's not irrelevant when it comes to the SANE report.
She said they used a condom so no Sperm was expected. Are you telling me that didn't put a sample under a microscope?
I assume Crystal is on the pill and was confident that her "donor" doesn't have aids since she was having unprotected sex.
Is her boyfriend white or black?? That has to be a distinguishing marker in a DNA test and the hair without the root UNDER A MICROSCOPE also would likely make the distinction.
Guess what I'm thinking is that her "boyfriend" might be white.
