I remember for the shooting outside of CIA HQ in Langley the FBI Latent Section ID’ed their suspect off of recovered cartridge casings fired from an AK-47. Granted those casings are much bigger then standard casings so there is more surface area to leave a print, but it does get cycled and ejected.
My two cents is that if it is possible to recover a print from a casing you should try, especially if it is a homicide. That is pretty strong evidence to say the suspect’s print was found on the casing that contained the bullet that killed the victim.

RLT---I had another one but it does not count as it was post firing contamination (ID to the Investigator).

I guess you do have the record. I would pay a golden Presidential dollar for a copy of the image of the one around the primer. I could fake one, but nothing beats the real thing.

Peter Griffin from Quahog----I think I know you. Do you have three kids. A boy who is a little round with an earring in the left ear and a daughter who always wears a knit cap and a baby named Stewey who is trying to take over the world.

I think I met you in LA but you know me by my real name "Kasier Sosay". Charles Parker is just an alias that I took off some jazz player whose nickname was "The Bird".

Anyway good information on the CIA Shooting. I did not realize they had done that.

I am willing to bet there are a lot more out there that are not being made public. If people hold that information back then other agencies will have the tendency to drop that type of processing believing that it is not productive.

Share the information people. If we do not then we are driving nails into our coffin. (Special Thanks to John Nielson for that one).

I do remember meeting you Kasier. I believe it was at the “Great Characters of Film and Television” lecture at UCLA put on by Dr. Howser. Do you remember hitting the clubs with Inigo Montoya that Friday? Those were the days.

Charles Parker is a good alias; I should probably look into making one.

“Anonymity…it’s like a warm blanket.”

The intent of the original post was obviously just to obtain journal information, however, in light of everyone's responses, I think a new study may be in order...
I will be working on a few ideas as to how to best go about this and cover information that has not yet been covered, but if anyone has any ideas for published studies/information they wish we had available, please feel free to let me know!
I would prefer to assist the field as a whole rather than just my agency and our needs (and my own curiosity).



Thanks again for everyone's help, and please, keep it comin'!

I ran across this article while looking for something else. Although the title just says brass in the article, although the article also shows a cartridge (live round) and a casing (spent). The title is:

Developing Prints on Brass
By Chief Inspector Zvi Lieber
Identification Branch
Israel Police Force
Tel-Aviv, Israel

Published in the "Fingerprint and Identification Magazine" Vol. 41, No. 4, October 1959.

The article discusses the use of copper carbonate (CuCO3) and ammonium hydroxide (NH4OH).

I suspect this is pretty close to being like Gun Blue or Gun Black as they only discuss it's use on brass.
