Analysis

For the D20S88 Locus, we can make the following conclusions:

Blood Spot 1 excludes all but Suspect 1. Suspect 1 matches the bands exactly.
Blood Spot 2 excludes only Suspect 2. The victim and Suspects 1 & 3 are consistent with this mixture of blood.
The Vaginal Swab excludes Suspect 2. The victim and Suspects 1 & 3 are consistent with this sample. Notice that there are two "unaccounted" bands. These bands may come from another individual -- either another rapist or someone else who has recently has sex with the victim (a consensual partner).
