CONTINUED CROSS EXAMINATION BY JA:
She was told the tape was found in an area that would have water coming into it and like a swampy type area.
If water was coming in and receding out and drying, it is possible that the DNA would start to degrade over time. The same answer would apply to the other items she was asked to examine from the scene.
FBI does not actually do paternity tests. In examining the family DNA samples, Caylee's bone marrow....
OBJECTION BY JB - OVERRULED
Paternity test - she generated the DNA type from LA. Then took ICA's type and compared to determine that LA could not be Caylee's father.
Stain in trunk is not blood. Can't tell anything else.
Only DNA on anything from the scene is explainable by DNA from lab personnel.
OBJECTION BY JB - OVERRULED.
REDIRECT EXAMINATION BY JB:
Regarding decomp in the trunk, as cells break down, DNA diminishes. She can't say as to what point during decomp she would not be able to get DNA? She stated it depends what you are trying to achieve. Blood, tissues and fluids will start to degrade. Bones will last longer. Does this happen at the latter part?
OBJECTION - leading - SUSTAINED.
Does that happen at the latter part?
OBJECTION - leading - OVERRULED.
She stated that there are environmental factors at play. She cannot say where the period of time is that she could no longer give a result. She could say that she did not get DNA or blood from the trunk of the car.
At the early stages of decomp, the possibility of blood leaking out would exist.
Possible to leak onto the trunk liner?
OBJECTION - OVERRULED.
If a body is placed in a trunk, the fluids will start to dissipate onto the liner if not contained in a protective material. If it was in a bag, it is possible that fluids could leak out of where the bag is tied up.
Regarding items collected from the scene, contaminated parts?
OBJECTION - leading - SUSTAINED.
Testifying regarding protocols?
OBJECTION - leading - SUSTAINED.
When answering as to what was found at the scene, that was based on her FBI report which is based on the SOP's of the lab.
The 17 allele was taken into consideration in her report - but as it related to it being inconclusive.
Regarding outside elements and the potential to find DNA, is there an expectation that if duct tape was placed around someone's mouth...
OBJECTION - leading - SUSTAINED.
She would expect that if there was DNA recovered, it would be more likely to be on the sticky side.
RECROSS BY JA:
When fluids leave the body, they continue to decompose.
WITNESS IS EXCUSED.
RECESS UNTIL 3:05
