Quadrant I (not washed): All surfaces had bright luminescent
handprints. Quadrant II (washed with warm tap water): A lumines-
cent pattern of parts of the handprint was detected on the bare
wood, varnished wood and cement. All other surfaces had large
bright luminescent areas, but no visible patterns. Quadrant III
(washed with soap and warm tap water): All surfaces had large
bright luminescent areas, but no visible patterns. To determine if
this luminescence was due to a substance in the soap, an area of tile
without any blood present was washed in the same manner and
treated with luminol. No luminescent areas were present, indicat-
ing the soap was not interferring with the test. Quadrant IV:
(washed with bleach): A very faint handprint was visible on the
bare wood, varnished wood and horizontal sheetrock. Areas of
faint luminescence were visible on the vertical sheetrock, tile and
cement. Only the edges of the washed area on the carpet showed
any luminescence.
