>> My name is Brandon McCollum, and I'm a forensic DNA examiner
for the Federal Bureau of Investigation.
So when I'm handing a specific case, I need to look at the evidence that's submitted
in the case from a DNA perspective, and I determine what evidence I'm going
to test and how it's going to be tested.
Once we generate results from those tests, I'll then interpret that information that we gathered
from the testing procedures, and then I provide that information to investigators in the field.
If necessary at any point, I then have to testify in the court of law to the results
that I've obtained through the DNA testing at the FBI.
