Day Three: Sealed gunshot residue kits opened in court

Elana Foster of RJ Lee Group in Pennsylvania is shown a copy of her report by the prosecution in order to refresh her memory of the analysis done on April 15th of materials from the UPD.

2 Gunshot residue kits were received on Sunday, Foster says. She says that it is received at the front desk by a receptionist, and hten picked up by someone in the forensics department. The evidence was then secured in the forensics department, Foster said.

On Monday, April 16th, Foster says, she retrieved the kits when she got to work. The SEM and the Atomic Absorption Kit (AAK) which were sent to RJ Lee Group are brought into evidence and shown to Foster.

Foster confirms that the seals were intact on the kits when she received them. Prosecution then asks her to open up the now sealed kits (which Foster says she sealed after testing).

The AAK kit is opened first and is explained as an older type of testing kit.

Foster is asked is she conducted a testing of these kits. She checks her notes. She says kits were analyzed on April 17th according to her notes.

ICPMS, Foster says, is a took that takes a liquid solution and tells you what type of metals are present. She says its often used to anaylze drinking water. Results of the analysis of these kits were that no significance could be attached to antimony and barium found in the samples. She says that what that means is that when results came back, it didn't match the FBI's standard levels of antimony to reach a positive.
