EVIDENCE DESCRIPTION:

Item 72: Submitted swab from north wall of stairwell
Item 73: Submitted swab from half wall
Item 74: Submitted swab from 2nd floor table
Item 75: Submitted swab from 2nd floor outside of bedroom
Item 76: Submitted swab from living room table
Item 77: Submitted swab from 3rd floor door
Item 78: Submitted swab of stain on floor near west bedroom
Item 101.1: Stain on cutting from uncased pillow from
Item 103.1: Stain A on bottom portion of mattress protector from
Item 103.2: Stain B on bottom portion of mattress protector from
Item 103.3: Stain C on bottom portion of mattress protector from
Item 108: Reference oral swabs from Bryan Kohberger
Item 110: DNA extracts from Items 72 through 78, 101.1, 103.1, 103.2, 103.3, and 108
CONCLUSIONS AND INTERPRETATIONS:

Deoxyribonucleic Acid (DNA) Analysis, employing the Polymerase Chain Reaction (PCR), was used to generate a Short Tandem Repeat (STR) profile from a portion of Items 72 through 78, 101.1, 103.1, 103.2, 103.3, and 108.1 The DNA profile previously obtained from Item 1.1 (See Report No. 4, issued 11/20/2022) matches that obtained from the known reference sample of Bryan Kohberger. This DNA profile is at least 5.37 octillion (5.37 x 1027) times more likely to be seen if Bryan Kohberger is the source than if an unrelated individual randomly selected from the general population is the source.

Laboratory Case Number: M2022-4843 Report No.:
26 The DNA profile previously obtained from Item 1.4 (See Report No. 4, issued 11/20/2022) indicates a mixture of DNA with a major profile. Assuming a two person mixture, Bryan Kohberger is excluded as being a contributor to this DNA mixture.

The DNA profile previously obtained from Item 6.1 (See Report No. 7, issued 11/23/2022) indicates a mixture of DNA. Assuming a two person mixture, Bryan Kohberger is excluded as being a contributor to this DNA mixture.

The DNA profile previously obtained from Item 9.1 (See Report No. 7, issued 11/23/2022) indicates a mixture of DNA with a major profile. Assuming a two person mixture, Bryan Kohberger is excluded as being a contributor to this DNA mixture.

The DNA profile previously obtained from Item 10.1 (See Report No. 7, issued 11/23/2022) indicates a mixture of DNA with a major profile. Assuming a two person mixture, Bryan Kohberger is excluded as being a contributor to this DNA mixture.

The DNA profile previously obtained from Item 13.1 (See Report No. 7, issued 11/23/2022) indicates a mixture of DNA, assumed to be from three individuals, with a major profile. Based on the likelihood ratio result 0.0469, it is inconclusive whether Bryan Kohberger is a potential contributor to this DNA mixture.

The DNA profile previously obtained from Item 23 (See Report No. 13, issued 12/17/2022) indicates a mixture of DNA with a major profile. Assuming a two person mixture, Bryan Kogberger is excluded as being a contributor to this DNA mixture.

The DNA profile previously obtained from Item 30 (See Report No. 13, issued 12/17/2022) indicates a mixture of DNA, assumed to be from three individuals, with a major profile. Bryan Kohberger is not the source of the major male DNA profile from this item. Due to the low level results and limited data, no conclusions can be made regarding the minor contributors.

The DNA profiles previously obtained from Items 37.1 and 37.2 (See Report No. 13, issued
12/17/2022) were determined to be from the same unknown male. Bryan Kohberger is not the source of the DNA profiles from these items.

The partial DNA profile previously obtained from Item 40.1 (See Report No. 13, issued 12/17/2022) was determined to be from an unknown male. Bryan Kohberger is not the source of the DNA profile from this item.

The partial DNA profile previously obtained from Item 40.4 (See Report No. 13, issued 12/17/2022) indicates a mixture of DNA with a major profile. Assuming a two person mixture, Bryan Kohberger is not the source of the major male DNA profile from this item. Due to the low level results and limited data, no conclusions can be made regarding the minor contributor.

Laboratory Case Number: M2022-4843 Report No.:
26 The DNA profile obtained from Item 72 indicates a mixture of DNA with a major profile, which matches that previously obtained from the known reference sample of Kaylee Goncalves (See Item 14, Report No. 4, issued 11/20/2022). Assuming a two person mixture, this DNA profile is at least 779 septillion (7.79 x 1026) times more likely to be seen if it were the result of a mixture of DNA from Kaylee Goncalves and an unrelated, randomly selected individual than if it resulted from two unrelated individuals randomly selected from the general population.

Madison Mogen (See Item 11, Report No. 4, issued 11/20/2022) is a potential contributor to the minor component of this mixture. Assuming a two person mixture, this DNA profile is at least 6.83 septillion (6.83 x 1024) times more likely to be seen if it were the result of a mixture of DNA from Madison Mogen and an unrelated, randomly selected individual than if it resulted from two unrelated individuals randomly selected from the general population.

Ethan Chapin (Item 5), Xana Kernodle (████████████████████████████████████████ ████████████████████████████████████████ ████████████████████████████████████████ Item 8), ██████████████████████ ████████████████████████
███████████████████ and Bryan Kohberger are ████████████████████████████████████████ ████████████████████████████████████████ ████████████████████████████████████████ excluded as contributors to this DNA mixture.

The DNA profile obtained from Item 73 indicates a mixture of DNA with a major profile, which matches that previously obtained from the known reference sample of Kaylee Goncalves. Assuming a two person mixture, this DNA profile is at least 525 septillion (5.25 x 1026) times more likely to be seen if it were the result of a mixture of DNA from Kaylee Goncalves and an unrelated, randomly selected individual than if it resulted from two unrelated individuals randomly selected from the general population.

Madison Mogen is a potential contributor to the minor component of this mixture. Assuming a two person mixture, this DNA profile is at least 44.6 quadrillion (4.46 x 1016) times more likely to be seen if it were the result of a mixture of DNA from Madison Mogen and an unrelated, randomly selected individual than if it resulted from two unrelated individuals randomly selected from the general population.

Ethan Chapin, Xana Kernodle, ████████████████████████████████████████ ████████████████████████████████████████
████████████████ and Bryan Kohberger are ████████████████████████████████████████ excluded as contributors to this DNA mixture.

The DNA profiles obtained from Items 74, 75, and 78 match that previously obtained from the known reference sample of Xana Kernodle. This DNA profile is at least 9.25 septillion (9.25 x 1024) times more likely to be seen if Xana Kernodle is the source than if an unrelated individual randomly selected from the general population is the source.

The DNA profiles obtained from Items 76 and 77 match that previously obtained from the known reference sample of Kaylee Goncalves. This DNA profile is at least 1.01 octillion (1.01 x 1027) times more likely to be seen if Kaylee Goncalves is the source than if an unrelated individual randomly selected from the general population is the source.

The DNA profiles obtained from Items 101.1, 103.1, 103.2, and 103.3 are consistent with that obtained from the known reference sample of Bryan Kohberger.
