Evidence: Forensic Analysis of chemistry, blood, DNA, and hair
 

YOKNAPATAWPHA COUNTY SHERIFF'S DEPARTMENT

Investigating Officer(s): Det. S. Murphy. Det. T. Armstrong

Incident No.: 000524-27A-2001

Case Description: Melissa Hammond Homicide

The following report on forensic analysis results was received from the State Crime Lab on March 20, 2001.

Chemistry

000524-15 through 000524-18: Four (4) fingernail pieces, broken, dark red or maroon on one face, natural color on opposite face

Chemical, as well as ridge analysis of the fingernail polish enamel on the fingernails recovered at the crime scene (000524-15 through 000524-18) is consistent with fingernail #3 found from vacuum C of the Farrell Motors car dealership.

Serology

00524-15 through 000524-18: Of the four fingernail pieces, sufficient DNA was available under 00524-15 and 00524-16 (right forefinger and middle finger). Tissue underneath the two fingernails was analyzed using both DQ Alpha and Polymarker analysis. The DQ Alpha test monitors for the presence of six different alleles at the DQ Alpha locus: 1.1, 1.2, 1.3, 2, 3, or 4. The tissue samples removed from underneath the victim's fingernails were further amplified so that the Polymarker analysis could be performed. The Polymarker test analyzes five different loci (LDLR, GYPA, HBGG, DYS8 and GC) that have 2 to 3 allelic possibilities. Because of the nature of the sample, contamination or mixtures of profiles can occur. Therefore, the Polymarker test was used to further characterize the profiles in the skin tissue. Because DNA from one single individual should only show either a homozygous (two of the same alleles) or heterozygous (two different alleles) genotype, observation of three or more alleles in a sample indicates a mixture. As well, in an unknown sample, the presence of only two alleles does not ensure a single individual as it can also indicate a mixture of two homogygous genotypes. But by analyzing the genotypes at six different loci, more information can be gained in mixed samples.

DQ Alpha Analysis

A=Melissa Hammond (1.1, 1.1)
B=Lydia Hammond (1.1, 4)
C=Steve Kirby (2, 3)
D= JP Wallace (1.3, 2)
E=Roger Hammond (2, 4)
F=Kevin Travers (3, 4)
G=Skin Sample #1 (alleles represented = 1.1, 1.3, 2, 4 and possibly 1.2; mixture of 2+ individuals)
H=Skin sample #2 (alleles represented = 1.1, 2, 3, 4, possibly 1.2; mixture of 2+ individuals)
"C" on each test strip = control

From the results of the DQ Alpha analysis, only Steve Kirby and Kevin Travers are eliminated as a donor of the skin under skin sample #1 and only JP Wallace is eliminated as a donor of the skin from skin sample #2.

Polymarker Analysis

From the results of the Polymarker analysis, Kevin Travers (at both the GYPA and HBGG locus) is eliminated as a donor of skin sample #1. In sample #2, Kevin Travers (at locus GYPA and DYS8) is eliminated. As well, Steve Kirby (at loci DYS8 and GC) is eliminated. Taking both tests together (DQ Alpha and Polymarker), Kevin Travers and Steve Kirby can be eliminated as being the donor of both tissue samples. JP Wallace can be eliminated as the donor from only sample #2.
