FIG 024, submitted by Charlie Parker

This week I jumped back to distortion/interesting and away from scars and disruptions. The FIG this week is from a trigger of a firearm (pistol 9mm). Now I have only seen 4 others from triggers. Two from agencies I have worked in the past, one from Phoenix and one from Washington State. It is not something you see very often. I am sure there are some people that see them once a week but for me, they are a rare occurrence.

1st download and open the latent print (link at the bottom) and look at it to determine orientation. Now it was processed with CA Fuming and then dye stained and captured with a Canon digital camera.

2nd Open the inked print marked FIG24AIP. I apologize for the inked print but out of four sets of cards on this subject this is the only one where the detail above the core was not smudged and since it is a live scan, the thumb cut into the right side of the inked print. We are working on getting another set.

3rd Open the 1-1. The latent has been color corrected and converted with PS-CS. Some minutiae have been marked. We could get additional minutiae by going down and to the right on a different card. I apologize for the orientation, but I threw this one together real fast and I am going back in to rescan it with the correct orientation.

I think it is interesting (besides being from a trigger) by the transition area from the movement smear at the bottom left of the latent and then to the clear ridge structure. The smear area to the bottom left did give us a little problem with orientation in the beginning, but the examiner stuck with it and resolved the distortion problem. When doing the Analysis always look for transitions. Also the preverbal three going in and two coming out at the dark area to the top right center.
