The following images are not high-resolution images.  These images are meant to display elements of analysis only, and should not be used for comparison purposes.  Use the following analysis concepts, but do so on a photograph which is as close to the original evidence as possible.  For more details on where to obtain such a photograph, you may e-mail kaseywertheim@aol.com.

Latent print only

Deposition Distortion (Substrate distortion circled)
Straight edges are not indicative of a double touch.

One might expect the ridges to smear and fan out if the tip of this finger
had rotated during deposition.  That doesn't appear to be the case.
Further, one would expect circular slippage, which is not found.

Pressure Distortion, based on ridge thickness and color shifts
This combined with Deposition Distortion indicates a core to tip motion
with no twist, and a heavy deposition pressure right before release.

Clarity levels (to set tolerance going in to the comparison)

Ridge Analysis (heaviest parts of ridge contact / matrix deposition)

Over-lay on the print with areas of minutia based on tolerance.
(higher tolerance = bigger red area, low tolerance = smaller red area)

Comparison between minutia in known print

Dots show location of minutia points marked on recent enlargements
Notice two dots around one characteristic in the latent (right top of group)

One obvious difference

Some claim a 68 degree rotation and shift to the position shown above.
As shown, the actual rotation is only about 6 degrees.

But the print would have had to have shifted almost 8 ridges in order to make this fit.

There is no evidence of this large of a shift, either in the ridge flow or the edge of the print.
