his technique is called yi 0.5 Rough Lift.” It is very difficult to lift latent prints from
grainy surfaces such as the dash board or steering wheels of cars, oxidized exterior air
conditioners, metal doors, and many other surfaces. Using regular lifting tape will not
sufficiently recover a latent print from the lower regions of a textured surface.
Therefore, the following technique is an excellent way of recovering those difficult prints from
textured surfaces.
This technique is to be employed after photographing the print in a field situation where this
method is being used to produce an item of evidence; it is not necessary to photograph the print
during this lab

First, cut several six-inch squares from your textured plastic tablecloth. Second, break open your
old toner cartridge to recover the remaining bit of toner in the cartridge. Place the toner into
your old coffee cup, and set it aside.
Next, take one of you squares that you cut from the rough plastic tablecloth, and place an oily
(rub your forehead for adequate oil) thumb print in the middle of the table cloth square.
Then, take your small paint or make-up brush and dip it into the toner in the bottom of your
coffee cup. Make sure that all excess powder is off of the brush by lightly tapping the brush with
your finger. Too much powder will cause a problem in developing your latent print.
Then, place your square of tablecloth on a flat solid surface, and brush lightly over your known
fingerprint going in a circular motion. Continue working on the print until it is developed well
enough to see clearly. This may take several attempts; this is why you cut several squares from
the tablecloth.
Lab Directions: Part 3
Once the latent print is developed to your satisfaction, place a drop of Elmeryi 0.5 s Blue Gel
Glue, about the size of a dime, directly under your developed latent fingerprint; it should be
just touching the edge of your print. Using the plastic drinking straw, placed just under the drop
of glue, blow through the straw onto the drop of glue (Caution: be sure to exhale and not inhale)
and spread the glue over the developed latent print. Completely cover the print so that a bit of
glue extends just over the edges of the fingerprint. More or less glue can be used to accomplish
additional tests on lifting your print in subsequent attempts at this technique; the amount will
depend on your liking. Allow the glue to dry completely over the print. In the field, you can use
incandescent lighting to accelerate the process. Once the glue has dried over the fingerprint,
take your sharp-pointed knife tip and lightly cut or score around the edges of your fingerprint;
thus making it easier to lift. Care should be taken not to damage the fingerprint; just a very
light scoring is all that is needed. Next, place wide Scotch tape over the glue-covered
fingerprint. You may wish to lightly rub the tape down on the surface of the glue. Do not stick
your tape firmly down as if you expect it to stick to the tablecloth.
Lab Directions: Part 4:
Then, pull back on the Scotch tape from one end back over to top of the glued fingerprint. This
should pull the dried glue off of the surface of the tablecloth with the latent print and glue
attached to the tape. Carefully re-tape your latent print and drop of glue onto a piece of white
paper to preserve the print and enter it into evidence.
Repeat this methodology several times until you become proficient at recovering a latent print
from a rough textured surface. Post your synopsis on the Lab 2 Discussion Board so that others may
read and comment on three of your classmates’ lab findings postings.Click Here For Details on How to Complete this Paper……
