Help with silencers data

(1/1)

LMMF:
Hello, to you all.

New in the forum, I´m a Forensic Sciences PhD Student from Portugal, with a Law degree and 10 years experience in sport shooting (IPSC, also R.O. with IROA Level I and II Seminars)

Did the Forensic Ballistic Investigation course in Cranfield University, U.K. in 2011.

I´m doing some research in GSR´s and I would like to work in my thesis with silencers, can anyone give me some "lights", please?

I´ve read some articles stating that it was not possible to find GSR´s in the victim clothes when shooting a 9x19mm pistol with a silencer at close range.

I find it hard to believe, because I could identify and quantify GSR´s in a t-shirt that was strike by 3 shots fired from a suppressed Walther P22 using ICP-MS.

Any help, please?!

Thank you for your time.

Best regards

afss:
1. Ofcourse you can find GSR on the target, because some of the gasses that pushes the bullet will also push out GSR.
2. If it a silencer that was allready used before, you might find GSR from previous shots! These residues were left in the silencer and the new shot pushed them out.
3. It is a good subject fo r research :-)
