DNA Test Results
Initially the importance of blood on the cat was discounted. Fortunately,
it was discovered that the Veterinarian had retained blood-stained cat hair
samples. These samples were tested.
A DNA test was performed by the Mississippi Paternity Testing Laboratory
using RFLP (Restriction Fragment Length Polymorphism) mapping, a technique
pioneered by the Metro-Dade Police Department Lab in crime scene evidence
analysis. Samples from Giblin, the victim and the cat were compared against
the blood-stained cat hair.
The blood samples retrieved from the cat hair do not match any of the
participants in the case. The blood came from a third party. However,
there is an unusual match, marked A, on the diagram. Gender specific
banding, marked B, indicates the sample was from a male.
