Note: Some findings have been condensed and/or simplified for inclusion in this report.

Items obtained from the search of the residence and vehicle of Weldon Foyle were examined using an alternate light source for the presence of human biological evidence. The items analyzed included:

    • Results: Found to contain possible biological material in the interior of the bag. The stain was negative for the presence of blood.
