Sequential Processing

[JJ]

I'm looking for the most current sequential processing procedures. Currently I'm studying the sequential processing chart from Armor Forensics. Is this chart outdated Looking to use the info for a job interview. Any help very much appreciated.

Hi JJ

I originally wrote those Armor Forensics sequential processing charts when I worked for Lightning Powder Company in 1997/1998. I don't know that they have been updated since them. Basically, I started with the Home Office Manual of Fingerprint Development Techniques. In that big binder, the processing charts are not straight line flowcharts and they include many techniques not available to the average US fingerprint operation. So I took the Home Office charts, simplified them, and made them straight line charts. So, those old charts I did for Lightning are ten years old, which makes them out of date and incomplete. But I still think for most small to medium sized police departments, they offer a good, solid reference for latent print development techniques.

So, if your job interview is with some agency that fits that description, those charts will do you well. If you are looking at a mores sophisticated laboratory with more demanding philosophy of sequential processing, I would suggest you get a copy of the Home Office Manual.

Hi JJ,

I agree with Pat that the Home Office Manual is very helpful.

May I also suggest to check out the Chesapeake Bay Division's web site and look over its Selection & Sequencing of Latent Fingerprint Processing Techniques.

Go to the following URL: http://www.cbdiai.org/

Then click on the "crab icon" that is by "CHEMICAL REAGENTS."

It's an interactive chart that many have found to be a helpful resource.

Best Wishes,

Bill
