A: I WAS ABLE TO MAKE USE OF FAYE SPRINGER, A CRIMINALIST AT THE SACRAMENTO COUNTY CRIME LABORATORY, AND THEY HAVE A MICROSPECTROPHOTOMETER. AND I TRANSPORTED THE FIBERS, THE ORANGE FIBERS, THE ONE COLLECTED FROM THE NECKLACE AND SEVERAL COLLECTED FROM ITEM NUMBER 5, THE LAUNDRY OUT OF THE WASHING MACHINE, TO SACRAMENTO AND USED THE MICROSPECTROPHOTOMETER IN SACRAMENTO.
Q: HOW DID THAT WORK IN TERMS OF YOUR ABILITY TO USE IT IN SACRAMENTO?
A: I WAS INSTRUCTED BY FAYE SPRINGER AND TOGETHER WE ANALYZED THE FIBERS.
Q: WHAT DOES THIS MICROSPECTROPHOTOMETER DO?
A: IT'S ACTUALLY VERY MUCH LIKE THE INFRARED SPECTROPHOTOMETER. WE'RE JUST USING A DIFFERENT RANGE OF LIGHT. AND IT'S A WAY TO QUANTITATE THE ABSORBANCE OF A COLOR THAT A FIBER HAS. SO THERE COULD BE SEVERAL DIFFERENT TYPES OF ORANGE FIBER DYE, BUT THEY WILL ABSORB LIGHT DIFFERENTLY BASED UPON THEIR DIFFERENT COMPONENTS. SO YOU WOULD EXPECT TWO FIBERS THAT WERE DYED THE SAME WAY TO ABSORB THE SAME WAVE LENGTHS OF LIGHT AND TWO FIBERS THAT ARE DYED IN A DIFFERENT WAY TO ABSORB DIFFERENT WAVE LENGTHS OF LIGHT. SO BY RUNNING THE FIBERS THROUGH THIS PARTICULAR INSTRUMENT, WE WERE ABLE TO DETERMINE WHETHER OR NOT THE FIBER FROM THE NECKLACE ABSORBED LIGHT IN THE SAME WAY AS THE FIBERS TAKEN FROM THE LAUNDRY.
Q: JUST SO WE'RE CLEAR, YOU USED BOTH A MACROSCOPIC AND A MICROSCOPIC COMPARISON ON THESE ORANGE FIBERS FOUND IN THE DEFENDANT'S HOME AND IN THE NECKLACE OF DANIELLE VAN DAM, CORRECT?
A: YES.
Q: YOU ALSO PERFORMED THE INFRARED CHEMICAL TEST ON THOSE FIBERS AS WELL, CORRECT?
A: CORRECT.
Q: AND ON AT LEAST THE FIBER FROM THE NECKLACE AND ORANGE FIBERS TAKEN FROM THE LAUNDRY AT WASHER YOU ALSO USED THE MICROSPECTROPHOTOMETER DEVICE, IS THAT CORRECT?
A: THAT'S CORRECT.
Q: WITH WHAT RESULTS?
A: IN EVERY WAY THAT I COULD MEASURE THE CHARACTERISTICS OF THE FIBER TAKEN FROM THE NECKLACE AND EVERY CHARACTERISTIC I COULD LOOK AT, THEY WERE SIMILAR TO THE FIBERS THAT WERE FOUND IN THE LAUNDRY BOTH IN ITEM NUMBER 5, 6, 7, AND 9.
Q: WHAT CAN YOU TELL US ABOUT WHETHER OR NOT THE FIBER FOUND IN DANIELLE'S NECKLACE COULD OR COULDN'T HAVE COME FROM THE SAME SOURCE AS THE FIBERS FOUND IN ITEMS 5, 6, 7 IN THE LAUNDRY ROOM AND THE BEDDING, NUMBER 9?
A: I CAN TELL YOU THAT BASED UPON THE TESTS CONDUCTED THAT THE FIBER TAKEN FROM THE VICTIM'S NECKLACE COULD SHARE A COMMON SOURCE WITH THE FIBERS TAKEN FROM THE LAUNDRY AND THE BEDDING
This is testimony I posted the other day. The analysis includes testing the color.
Now, someone may want to argue the finer points of the testing, but I think I have established I have a reasonable basis for my assertion and that would mean I am not lying.
