REPORT

Case: Chandler #1234

Suspect: / LENNOX, Terry

Evidence:

Item 1 / Hat left at crime scene

Reference:

Item 2 / Buccal swabs from Terry Lennox

METHODS:

·  The method of deoxyribonucleic acid (DNA) analysis used was the Polymerase Chain Reaction (PCR). DNA was isolated from the items listed above.

·  The PCR amplification kit used was the PowerPlexâ 16 System.

·  The PowerPlexâ 16 System contains 16 genetic loci (D3S1358, TH01, D21S11, D18S51, Penta E, D5S818, D13S317, D7S820, D16S539, CSF1PO, Penta D, vWA, D8S1179, TPOX, FGA and Amelogenin, a gender determining locus which is not used for statistical purposes).

·  The types detected for each sample can be found in the attached table.


RESULTS:

Hat

The data indicated that a partial profile containing DNA from two or more individuals was obtained from the hat (Item 1). A total of thirty-two alleles were detected above this laboratory's interpretational threshold at thirteen of the fifteen tested STR loci. No conclusions could be drawn regarding Terry Lennox (Item 2) as a possible contributor to the DNA obtained from this sample, due to the possibility of allele drop-out due to low levels of amplified DNA.
