Court Filing
EXHIBIT S-8 Amended Supplemental Expert Disclosure: Eric Seat The State has previously disclosed Eric Seat, Forensic Scientist, as an expert witness in the field of forensic biology and DNA, which includes, but in no way is limited to, DNA extraction, quantitation, amplification, analysis and interpretation / analysis (including but not limited to STR data, Y-STR data; and STRmix probabilistic genotyping). The State hereby incorporates its previous response and attachments filed on December 18, 2024, and is hereby supplementing its response as follows. Seat may testify regarding his involvement in this case in which he developed a male DNA profile from lab item 6 (reference oral sample from Connor Chesnut). DNA (Deoxyribonucleic acid) is genetic material contained in cells that may be utilized for human identification. DNA may be present on an item in the form of biological materials such as blood, semen, and saliva or may be left on an item when it is handled. Biological evidence and possible / potential DNA evidence is collected for preservation and may be sent for further testing by qualified analysts. DNA can be used to identify individuals, link individuals to crime scenes, link crime scenes, as well as exclude individuals from DNA profiles that we obtain. Seat will explain the four steps of DNA analysis such as the 1) extraction of DNA from cells, which is done by adding chemicals to a sample to break open the cells to release the DNA, 2) the quantitation of DNA (how much DNA is present in a sample), 3) the amplification of DNA, which is copying specific locations of DNA using polymerase chain reaction (PCR), (generating copies of DNA), and 4) the generation (visualizes the DNA profile, which looks like peaks on a graph) of a DNA profile for comparison. The involvement of Seat as well as his interpretations and conclusions can be found in Seat's Lab Report 3 (Bates Pages 5721-5731).
