being examined. 5 scene exhibits were also examined.
a- A positive presumptive test for blood was found on an article of clothing
from Alexandra and the nDNA profile matched that of the known sample
(pubic hair) from Alexandra. No male DNA typing profile was detected in
this area of her clothing.
b- Human DNA of insufficient quantity for nDNA analysis was detected on a
total of 7 different exhibits in different areas.
c-No DNA profiles and no DNA was detected on other exhibits.
d- Human body hair unsuitable for nDNA analysis was identified on an
e- No semen, no blood and no hair was found on other exhibits.

compared. No human DNA and no semen was detected. Additional hairs were

compared. Human DNA of insufficient quantity for nDNA analysis was detected.
No blood and no hair was identified.
