Recap #cclivechat Dec 16, 2011

Our chat today was with Gary Howard a.k.a. TriniCSI on Twitter and we discussed the chemical treatment of fingerprints. And despite mind-boggling technical difficulties we got an excellent conversation going.

We touched on the three types of fingerprints that can be found at a crime scene, blood transfers, latent and patent prints, and the different terminology for plastic prints. Gary also explained how to lift prints from vinyl gloves, remote transmission, the use of amido black and how it only responds to protein in blood and not just to protein. We briefly touched on gummy fingers and life in the sun.

The hour flew by but Gary is willing to answer any questions you have so if you do, post them below in the comment section and I’ll alert Gary that “he’s got mail!”

This was our last chat for 2011, themed or free style. We start 2012 on January 6 with a normal chat and on Jan 13, our guest is our very own Richard Case who will talk some more about fingerprints!

The verbatim chat is below.

Cheers, Vidster

TrickyCase@TriniCSI Still not a problem to me... and I have logged online and using tweetdeck #cclivechatFri, 16 Dec 2011 17:12:07 +0000
Vidocq_CC@TriniCSI Latent prints respond to leucocrystal violet due to the hemoglobin, correct? #cclivechatFri, 16 Dec 2011 17:12:56 +0000
TrickyCase@TriniCSI What was the 3rd.. visible... latent... ? #cclivechatFri, 16 Dec 2011 17:13:42 +0000
Vidocq_CC@TrickyCase plastic prints, visible prints, and true latent or invisible prints #cclivechatFri, 16 Dec 2011 17:14:43 +0000
TrickyCase@TriniCSI @Vidocq_CC what are patent prints when they're at home :s #cclivechatFri, 16 Dec 2011 17:16:05 +0000
Vidocq_CCThis is horrible, @triniCSI's tweets do not show up in my normal stream and not here in Tweetchat either. #cclivechatFri, 16 Dec 2011 17:16:06 +0000
LilacLounge@TriniCSI Gary, how would prints in blood be classified? #cclivechatFri, 16 Dec 2011 17:16:15 +0000
1jaclynwatson@Vidocq_CC @trinicsi mine either #cclivechat I'm just checking on my TL as I follow you all!Fri, 16 Dec 2011 17:17:22 +0000
LilacLounge@Vidocq_CC @triniCSI It's odd. I can't see Gary's tweets at all unless I look at the conversation from someone's reply #cclivechatFri, 16 Dec 2011 17:17:35 +0000
TrickyCaseI can see all... my computer has mystical twitter powers #cclivechatFri, 16 Dec 2011 17:17:44 +0000
Vidocq_CCRT @TriniCSI: Blood transfer patterns - when you have blood on you and then touch a third party/surface is called a pattern #cclivechatFri, 16 Dec 2011 17:18:25 +0000
Vidocq_CCRT @TriniCSI: latent prints are any not visable to the eye but through chemicals we can enhance them #cclivechatFri, 16 Dec 2011 17:18:39 +0000
LilacLounge@TrickyCase @TriniCSI @Vidocq_CC Are they prints on a shiny shoe? ;-) #cclivechatFri, 16 Dec 2011 17:18:47 +0000

TrickyCaseRT @TriniCSI: Only "patent" shoes Sue ;) #cclivechatFri, 16 Dec 2011 17:19:52 +0000
Vidocq_CC@trinicsi Has there ever been a case where a reaction on a latent print was caused by anything else but hemoglobin? #cclivechatFri, 16 Dec 2011 17:20:14 +0000
TrickyCaseI could retweet all of Garys tweets... but I predict a massive reduction in followers #cclivechatFri, 16 Dec 2011 17:20:45 +0000
Vidocq_CCAnother Q for @triniCSI: How often do you find a patent handprint with latent fingerprints? #cclivechatFri, 16 Dec 2011 17:21:14 +0000
Vidocq_CC@TrickyCase Pls do retweet because I cannot see them. I have never been unfollowed due to RT in this chat #cclivechatFri, 16 Dec 2011 17:21:45 +0000
TrickyCase@Vidocq_CC I know you wouldn't but some non-#cclivechat followers might :sFri, 16 Dec 2011 17:23:05 +0000
TrickyCaseRT @TriniCSI: @Vidocq_CC #cclivechat latent prints are not normally visible we use different chemicals to see them, depending on the surface they are onFri, 16 Dec 2011 17:23:18 +0000
Vidocq_CC@triniCSI Amido Black reacts with protein OR with protein found in blood? #cclivechatFri, 16 Dec 2011 17:23:31 +0000
Vidocq_CCCan anyone pls RT @triniCSI's tweets as I cannot see them? #cclivechatFri, 16 Dec 2011 17:23:57 +0000

LilacLounge@TriniCSI what are plastic prints? (I might have missed a tweet) #cclivechatFri, 16 Dec 2011 17:26:36 +0000
TrickyCaseRT @TriniCSI: Amido Black reacts with protein OR with protein found in blood? Protein in blood #cclivechatFri, 16 Dec 2011 17:26:52 +0000
Vidocq_CCHow do you make fingerprints on vinyl gloves visible? #cclivechatFri, 16 Dec 2011 17:28:46 +0000
TrickyCase@TriniCSI Do you refer to it as a plastic print? Sounds like an Americanism #cclivechat no offence to AmericansFri, 16 Dec 2011 17:28:51 +0000
Vidocq_CCRT @TriniCSI: plastic is a friction impression left in a material that retains the shape of the ridge detail - putty, clay etc #cclivechatFri, 16 Dec 2011 17:29:15 +0000
LilacLounge@TriniCSI Brilliant! Thanks. I'm following Gary on his profile page in a new tab. Clumsy but it works... #cclivechatFri, 16 Dec 2011 17:29:28 +0000
Vidocq_CC@TriniCSI No, sorry Gary. I have no clue why this is happening! #cclivechatFri, 16 Dec 2011 17:29:36 +0000
Vidocq_CCRT @TriniCSI: How do you make fingerprints on vinyl gloves visible? superglue is the best #cclivechatFri, 16 Dec 2011 17:30:15 +0000
Vidocq_CCCan you explain how you use the superglue to make prints on vinyl gloves visible? #cclivechatFri, 16 Dec 2011 17:30:45 +0000
LilacLounge@TriniCSI This has never happened before. I hope you will join us again for #cclivechat regardless of today's glitch :)Fri, 16 Dec 2011 17:30:51 +0000
Vidocq_CC@TrickyCase What would you call those prints, Richard? They do say plastic here. #cclivechatFri, 16 Dec 2011 17:31:25 +0000
TrickyCase@TriniCSI you live and learn :) #cclivechatFri, 16 Dec 2011 17:31:43 +0000
Vidocq_CC@LilacLounge I hope so, I'm embarasssed because he took the time and with the time difference .... #cclivechatFri, 16 Dec 2011 17:31:56 +0000

TrickyCase@Vidocq_CC I refer to them as 3d impressions.. thats what the training notes say in relation to footwear in a soft substrate #cclivechatFri, 16 Dec 2011 17:33:42 +0000
Vidocq_CCRT @TriniCSI: how to use superglue 4 prints on vinyl gloves visible? glue is applied through process which sticks to sweat left from ridges #cclivechatFri, 16 Dec 2011 17:33:48 +0000
Vidocq_CCDo you prefer superglue over gellifters? http://t.co/bm3DlRws #cclivechatFri, 16 Dec 2011 17:34:09 +0000
Vidocq_CC@TrickyCase Good to know, maybe something to repeat in your chat Jan 13, 2012 #cclivechatFri, 16 Dec 2011 17:34:38 +0000

Vidocq_CCRT @TriniCSI: sweat left from ridges is then visualised either with dye or light source to capture image of ridges #cclivechatFri, 16 Dec 2011 17:36:20 +0000
Vidocq_CC@JChaseNovelist Thanks for the RT! #cclivechatFri, 16 Dec 2011 17:36:48 +0000
TrickyCase@TriniCSI Gary.. have you ever divulged which force you work for? #cclivechatFri, 16 Dec 2011 17:37:12 +0000
TrickyCase@TriniCSI Cheers... I thought I was going mad #cclivechatFri, 16 Dec 2011 17:38:10 +0000
Vidocq_CCRT @TriniCSI: the problem with vinal gloves is the amount of sweat, causes layered prints #cclivechatFri, 16 Dec 2011 17:38:46 +0000
TrickyCase@TriniCSI Don't blame you.. I was just trying to think of some Q's, like do you use Remote Transmission #cclivechatFri, 16 Dec 2011 17:40:36 +0000
Vidocq_CCHow many times can you use Amido Black before it becomes unacceptable as evidence? #cclivechatFri, 16 Dec 2011 17:40:54 +0000
TrickyCaseRemote Transmission is the sending of marks digitally from the crime scene or CSI office #cclivechatFri, 16 Dec 2011 17:41:20 +0000
Vidocq_CCRT @TrickyCase: Remote Transmission is the sending of marks digitally from the crime scene or CSI office #cclivechatFri, 16 Dec 2011 17:41:57 +0000
Vidocq_CCRT @TriniCSI: @Vidocq_CC You can use any chemical process a number of times but when you have a good image you photo it, then stop #cclivechatFri, 16 Dec 2011 17:43:05 +0000
TrickyCase@TriniCSI I promote the use of RT... its good but has some issues... some forces do it and some are still looking into it #cclivechatFri, 16 Dec 2011 17:43:22 +0000
Vidocq_CCRT @TriniCSI: @Vidocq_CC Obviously, you want to capture the mark before you ruin it, which does happen #cclivechatFri, 16 Dec 2011 17:44:22 +0000
TrickyCase@TriniCSI If asked the majority will say they use Remote Transmission... but in truth most are still "playing" with it #cclivechatFri, 16 Dec 2011 17:44:26 +0000
LilacLounge@Vidocq_CC I'll have to duck out early. I have another commitment. Have a good weekend :) #cclivechatFri, 16 Dec 2011 17:44:28 +0000
Vidocq_CC@TriniCSI How many times using Amido Black will ruin a print? #cclivechatFri, 16 Dec 2011 17:44:59 +0000
